Unbiased Muscle Sport Clean Whey Review

This Muscle Sport Clean Whey Review is a special request from a YouTube subscriber. They wanted me to do a deep-dive on the protein options offered by MuscleSport. However, after examining Muscle Sport Clean Whey, save your money. Keep reading to find my cheat sheet for this Muscle Clean Whey Review. 

🔑 Muscle Sport Clean Whey Review, TL;DR

If you don’t want to read my full Muscle Sport Clean Whey Naturals Review, here’s your quick cheat sheet.

No Testing, No Proof – Zero Transparency on Quality
Muscle Sport Grass Fed Whey Protein Naturals offers no third-party testing, no Certificate of Analysis, and no amino acid profile. Every request for basic quality documentation—leucine content, country of origin, grass-fed certification—was ignored.

Grass-Fed Claim Without Grass-Fed Certification
The label claims “grass-fed whey,” but there’s no third-party verification or authenticity to the claim of “grass-fed whey.”

Premium Price, No Accountability
At $59.99 for 30 servings, this protein is priced like a premium product. But with no way to verify quality or sourcing, it feels more like label-driven hype than a clean-label protein with proof behind it.

Who Should Use This Protein Powder?

• Buyers who want a stevia-sweetened chocolate protein that mixes well
• Shoppers who prioritize taste over transparency and are okay with unverified label claims

Final Grade: 20.5/50 – 41% – Fails to Deliver
Muscle Sport Clean Whey Naturals looks clean, but the lack of transparency and customer support makes this one hard to recommend. Better options exist.

Thinking about buying Muscle Sport Protein? You’ll want to read this full review before you do—and here’s why:

No product information about testing standards, third-party certifications, or protein quality is available. While the website lists a California Prop 65 Warning, the container does not—something you should never see associated with a grass-fed whey protein. And let’s be clear: this protein is not certified grass-fed.

I’ve contacted the company multiple times for basic product information. There is no amino acid profile, sourcing verification, or silence.

Buyer beware—this isn’t transparency.

🔑 Is MuscleSport Clean Whey Amino Spiked? TL;DR

Yes, MuscleSport Clean Whey is amino-spiked. Muscle Sport International has ignored every request I’ve made for basic product information—silence. When a company avoids simple questions about quality and transparency, that’s a big-time red flag.

⚛️ Is MuscleSport Clean Whey Amino Spiked?

If you’re looking for an amino acid profile for MuscleSport Clean Whey, don’t bother checking the label or the website—it’s not there. I contacted Muscle Sport multiple times and couldn’t get a single answer. Not one representative had product knowledge. There was no support. There was no transparency.

💪 After Training Shake: Is One Serving of MuscleSport Grass Fed Whey Enough to Stimulate Muscle Protein Synthesis?

Research shows you need around 25 grams of protein and 2.5 to 3.0 grams of leucine post-workout to trigger muscle protein synthesis. MuscleSport Grass Fed Whey gives you 25 grams—but what about the leucine?

I’ve requested the amino acid profile from Muscle Sport International multiple times. I haven’t received a response, and there is no profile or transparency.

So, should you use MuscleSport Grass Fed Whey post-workout?

Based on the information we have, I wouldn’t. Without leucine data or third-party testing, MuscleSport Grass Fed Whey looks like little more than expensive empty calories. You’re better off with a protein powder that shows you what you’re getting.

Amino Spiking: 0 out of 10.
I’ve contacted MuscleSport Clean Whey multiple times to request product transparency. The only response I ever received was from someone in their marketing department, and it wasn’t reassuring. Their exact words? “These aren’t the types of questions customers usually ask.”

That response tells you everything. Is Muscle Sport International focused on helping you achieve your fitness goals or just selling a label without nutritional proof?

🔑 Is MuscleSport Third Party Tested? TL;DR

No. Clean Whey Protein Muscle Sport is not third-party tested—at least, there’s zero proof that it is. There is no cGMP label, testing data, or response from the company after multiple requests. I only found a phone number on the container to report adverse events. That’s not transparency—that’s damage control.

📜 Is MuscleSport Third Party Tested?

🐄 Is Muscle Sport Clean Whey Protein Grass Fed?

Normally, I’d point to my commonly cited AGN Roots article, where grass-fed whey’s amino acid profile and BCAA content are fully disclosed and verified. But with Muscle Sport Clean Whey Protein, there’s nothing to verify. The amino acid profile is not on the website or in the container, and after multiple requests, Muscle Sport International has not responded.

What can we say about Muscle Sport Clean Whey Protein and its claim to offer “grass-fed whey?” Muscle Sport Naturals isn’t verified, and we can’t verify the protein quality. It’s just a label offering advertising jargon to make a quick buck. 

⚠️ Clean Whey Protein Powder: Whey Protein Heavy Metals

As with all proteins I review, I contacted Clean Whey Protein Powder, requesting third-party testing for heavy metals. The company never responded. That silence is telling.

The product description page for Clean Whey Protein Powder includes a California Prop 65 warning indicating the presence of chemicals above the state’s safety limits. No Prop 65 warning is found on the container for comparison’s sake. For context, Prop 65 requires manufacturers to disclose whether their products contain substances linked to cancer or reproductive harm.

A protein marketed as “natural” and “grass-fed” should never include a warning like this. It undermines the clean-label image and raises legitimate concerns about sourcing and safety.

🌱 Grass Fed Whey Protein Reviews

Not every product labeled “grass-fed” deserves the title—and this Clean Whey Protein Review makes that clear. Muscle Sport Naturals promotes itself as a grass-fed whey isolate, but there’s no third-party testing, no amino acid profile, and no verified sourcing to prove the claim.

If this Clean Whey Protein Review has you questioning label claims, check out my Truly Grass-Fed Protein Guide—a full breakdown of certified brands with real traceability. My New Zealand Protein Powder Guide covers your best options for New Zealand-based products that meet strict dairy standards.

USDA Organic remains the strongest option for verified USA-based whey. If Clean Whey Protein Review has raised flags for you, my USDA Organic Whey Protein Guide and Grass-Fed Whey Protein Guide cover which brands deliver on their grass-fed claims—and which ones fall short.

🔑 Protein Powder Comparison? TL;DR

Trying to figure out how Whey Clean Muscle Protein stacks up? Here’s your fast-track summary.

1. AGN Roots: The gold standard in quality. Third-party tested, certified grass-fed, and a full amino profile. Far more transparent than Whey Clean Muscle Protein.
2. ON Gold Standard: The best value pick. It’s under $1.10/serving, includes a verified amino acid profile, and remains the go-to budget protein. Outperforms Whey Clean Muscle Protein in trust and track record.
3. BSN Syntha-6 Isolate: Great flavor, great mixability. While it uses a proprietary blend, it’s still more transparent than Whey Clean Muscle Protein and better as a milkshake-style post-workout.
4. Muscle Sport Clean Whey Naturals: Fewer ingredients, no artificial sweeteners, and a lower price per serving than Lean Whey. Still lacks testing, but if you choose inside the brand, this beats Whey Clean Muscle Protein.
5. Muscle Sport Lean Whey: Flashy label with underdosed extras. Fewer servings and a higher price tag make this the least favorable pick compared to Whey Clean Muscle Protein.
   

The bottom line is that Whey Clean Muscle Protein tries to market as “clean,” but better options exist at every price point unless there’s proof of sourcing or third-party testing.

📊 Protein Powder Comparison

🆚 Whey Protein Powder Comparison: ON Gold Standard Whey vs Muscle Sport Protein

Which is better? In ON Gold Standard Whey vs Muscle Sport Protein, you must examine transparency, sourcing credibility, and price. Both products market as post-workout shakes, but only one is backed by great customer service and information. It’s not MuscleSport!

Muscle Sport Whey Protein uses a grass-fed whey isolate and claims no artificial dyes or sweeteners. But that’s where the transparency ends. I repeatedly contacted MuscleSport requesting a third-party lab test, amino acid profile, or sourcing documentation. Nothing was provided—only what’s listed on the label.

In contrast, ON Gold Standard Whey combines whey isolate, concentrate, and hydrolysate. While it includes artificial sweeteners, it also publishes a full amino acid profile and has a long-standing reputation for consistency and value. It’s one of the few blended proteins still sharing sourcing practices and has never raised red flags for amino spiking.

Muscle Sport Whey Protein claims to be a clean-label product, but the lack of testing or customer support makes that claim hard to trust—especially at $2.00 per serving. Meanwhile, ON Gold Standard Whey is a go-to protein under $1.10 per scoop, with a verified profile and global availability.

The Bottom Line

ON Gold Standard Whey vs Muscle Sport Protein boils to established quality, transparency, and reputation. Optimum Nutrition is, without a doubt, the safer choice. Muscle Sport Whey Protein looks clean on the surface, but without verification, buyer beware. But if you want something that tastes better than Optimum Nutrition, Muscle Sport Naturals is a home run!

🆚 Whey Protein Powder Comparison: BSN Syntha 6 Isolate vs Muscle Sport Protein

When comparing BSN Syntha 6 Isolate vs Muscle Sport Protein, the biggest red flag is the same: no amino acid profile. But how that red flag is handled tells you everything.

BSN Syntha 6 Isolate uses a mix of isolate and milk protein isolate under the proprietary “ISOLAST” label. That’s already a problem. Add in the fact there’s no leucine disclosure and zero third-party testing, and it’s no surprise I flagged it as potentially amino spiked. That said, the Strawberry Milkshake flavor is excellent. Mixability is top-tier. And the 2g of fiber gives it light meal replacement potential.

Muscle Sport Protein Powder, specifically the Clean Whey Naturals line, uses grass-fed whey isolate and avoids artificial dyes and sweeteners. It leans into the “clean label” trend with natural flavoring and stevia. However, I contacted MuscleSport multiple times, and there was no response beyond what’s on the label. There is no amino acid profile, third-party testing, or proof that the whey is grass-fed. For $2.00 per serving, that’s not acceptable.

Both proteins chase the taste-first crowd. However, Muscle Sport Protein Powder hides behind the word “clean,” while BSN Syntha 6 Isolate openly uses a proprietary blend and still offers some level of transparency.

The Bottom Line

If you’re debating BSN Syntha 6 Isolate vs Muscle Sport Protein, BSN wins on flavor, label clarity, and price per serving. But if you want third-party tested, verified grass-fed protein, skip both and read my Nutrabio Grass Fed Isolate review and Syntha-6 Isolate review, or check out BSN Syntha 6 Isolate on Amazon.

🆚 Whey Protein Powder Comparison: AGN Roots vs Muscle Sport Protein

The difference between AGN Roots vs Muscle Sport Protein is between night and day. Both advertise as grass-fed whey protein powders, but only one backs it up with third-party testing and certification.

Grass-Fed Claims and Transparency
AGN Roots is certified Truly Grass-Fed, Informed Sport, Animal Welfare Approved, and Informed Protein. That means zero amino spiking, verified leucine content (3.05g per 25g), and year-round pasture grazing in Ireland. In contrast, Clean Whey Protein by Muscle Sport is a marketing-heavy product. While it says “Grass Fed” on the label, there are no sourcing disclosures or verifiable third-party certifications. After multiple requests to Muscle Sport, I received no amino profile, sourcing details, or further transparency beyond the label.

Ingredients and Additives
AGN Roots uses Truly Grass-fed whey isolate and non-GMO sunflower lecithin. Clean Whey Protein uses isolate and natural flavorings like cocoa powder and stevia—no artificial dyes or sweeteners. However, it still includes gums for texture.

The Bottom Line

If transparency and certified quality matter to you, AGN Roots Grass Fed Whey Protein is the superior choice. It’s verified, clean, and delivers elite BCAA content.

Clean Whey Protein may appeal to buyers who want a natural flavor without artificial sweeteners, but its lack of sourcing transparency and third-party testing hinders its appeal.

Buy AGN Roots Grass Fed Whey on Amazon if you want peace of mind in every scoop

🆚 Whey Protein Powder Comparison: Muscle Sport Lean Whey vs Muscle Sport Clean Whey Naturals

When comparing Muscle Sport Lean Whey vs Muscle Sport Clean Whey Naturals, the choice comes down to how much marketing fluff you’re willing to accept. Both are marketed as premium proteins, but neither provides third-party testing or an amino acid profile.

Muscle Sport Lean Whey uses a blend of isolate and hydrolyzed whey and adds CLA, MCTs, and L-carnitine—none clinically dosed. The flashy ingredients make it feel unique, but the 25g protein label can’t be verified without an amino acid profile. Plus, at $2.02 per serving, it’s all label marketing without the premium-price third-party verification.

Clean Whey Naturals removes artificial dyes, sweeteners, and other additives. It claims to be a grass-fed whey protein isolate, offering a simpler and more ingredient-conscious formula for fitness-goers who avoid artificial ingredients. However, Muscle Sport did not provide answers when asked to verify grass-fed sourcing, which is a problem.

Muscle Sport Lean Whey and Clean Whey Naturals are in the same buyer-beware category: they are premium products with no proof of quality. One offers extras to justify the cost, while the other uses clean-label marketing to do the same.

Clean Whey Naturals may be better if you prefer fewer ingredients and want to avoid artificial flavors. But make no mistake—neither product brings the level of transparency expected at this price.

Bottom Line

Whether you choose Muscle Sport Lean Whey or Clean Whey Naturals, the real question is this—are you buying quality or just the idea of it? It’s hard to call either a smart buy without testing or transparency. If forced to choose, Clean Whey Naturals edges ahead, but both are one follow-up email away from buyer’s remorse.

🥤 Mixing Directions for Clean Whey Naturals

The directions for MuscleSport Grass Fed Whey are pretty standard:
Take one scoop of MuscleSport Clean Whey, mix it with 8–10 oz of cold water (or your beverage), shake, and adjust for taste or consistency.

But let’s get to the real question—how does Clean Whey Naturals mix in a shaker?

It works surprisingly well. There are no clumps or gritty residues. Even if you plan to use it as a post-workout shake—which I wouldn’t recommend—it still delivers a smooth, thin texture with minimal effort.

⚖️ Does One Scoop of Clean Whey Naturals Equal One Serving?

One scoop of Clean Whey Naturals is 5 grams more than one serving. So go light with the scoop.

👌 Does Musclesport Grass Fed Whey Taste Good?

When you see a picture of what you’re expected to taste, it usually underdelivers. But in this case, MuscleSport Grass Fed Whey advertises chocolate ice cream with chocolate shavings—and the flavor gets pretty close.

As expected with any protein powder labeled “naturally flavored” and “no artificial sweeteners,” stevia is the default sweetener. And yes, you can taste it. The flavor leans more toward stevia-sweetened chocolate ice cream than anything rich or indulgent you’d get from a carton. Still, I’d argue the premium price tag reflects the overall flavor experience you’re getting from MuscleSport Grass Fed Whey.

Is it the best naturally flavored chocolate shake I’ve ever had? No. But on taste alone, it earns a solid 8 out of 10.

One last thing—the chocolate shavings are a nice touch. Just know they settle at the bottom of your shaker every time.

Mixability: 9.5 out of 10.

You’ll have no issues mixing MuscleSport Grass Fed Whey—it’s nearly flawless. Smooth consistency, no clumps, no effort. As for the flavor, it delivers exactly what you’d expect from a naturally flavored, stevia-sweetened protein. The stevia is noticeable, but it doesn’t overstay its welcome. It sneaks in, does its job, and doesn’t ruin the finish.

🔑 Muscle Sport Naturals Ingredients, TL;DR

Muscle Sport Naturals Protein Powder is advertised as a clean-label, grass-fed protein with “no artificial dyes or sweeteners.” While this always sounds great on a label, I’ve identified some major issues in its execution. The brand’s claims Are Not Transparent, and the powder does not have an amino acid profile, third-party lab results, or verified grass-fed sourcing.

Muscle Sport USA has not responded to multiple requests for ingredient origins. The company’s official response is to question why customers want that information.

Here’s the truth: Muscle Sport Naturals Protein Powder may taste good and offer decent mixability, but its “grass-fed” and “natural” label claims are unverifiable. Muscle Sport USA withholds sourcing info, leaving buyers with only front-of-label marketing.

Bottom Line:
If you’re looking for actual transparency or leucine data to track your intake, Muscle Sport Naturals Protein Powder doesn’t deliver. Without proof, it’s just another premium-priced powder riding on buzzwords.

📋 Muscle Sport Naturals Ingredients

Muscle Sport Naturals Protein claims to be a clean-label protein for health-conscious buyers who want something grass-fed, naturally sweetened, and easier on the stomach. But once you take a closer look at the ingredients, the gaps in transparency become more noticeable.

According to MuscleSport, Muscle Sport Naturals Protein is formulated with grass-fed whey isolate and natural inclusions for taste. However, the company hasn’t provided an amino acid content. You’re left trusting the front label—not the data behind it.

Here’s a breakdown of the Muscle Sport Naturals Protein Chocolate Ice Cream ingredients and what each one does:

Muscle Sport Clean Whey Ingredients: Chocolate Ice Cream
Ingredients	Purpose
Grass Fed Whey Protein Isolate	Primary protein source – “Grass Fed” claim not independently verified
Alkalized Cocoa Powder	Flavoring
Dark Chocolate Shavings (with Cocoa Mass, Cocoa Butter, Butter Oil, Soya Lecithins, Vanilla Extract)	Flavoring and emulsifiers
Natural Flavor	Vague FDA labeling that allows supplement companies to add more minerals
Gum Blend (Gum Acacia, Guar Gum, Xanthan Gum)	Thickening and stabilizing ingredients
Stevia Leaf Extract	Natural, zero-calorie sweeteners

Muscle Sport Naturals Protein is marketed as a grass-fed, clean-ingredient alternative to their Lean Whey formula. But without a published amino profile or independent verification of those grass-fed claims, it’s hard to confirm whether this product is premium—or just marketed that way.

That doesn’t mean Muscle Sport Naturals Protein is a bad choice. It mixes well, tastes decent, and avoids artificial sweeteners. But if ingredient transparency matters, especially for those tracking leucine intake or verifying grass-fed sourcing, you’ll want to keep asking questions.

🫘 What Is Soya Lecithins?

If you’ve reviewed protein powders as long as I have, you’ve probably seen sunflower lecithin or soy lecithin appear as emulsifiers. But What Is Soya Lecithins doing in a premium protein powder like Muscle Sport Naturals? I’ve reviewed over 100+ protein powders, and I can confidently say this isn’t normal.

What is soya Lecithin, exactly? It’s a soy-derived emulsifier that keeps ingredients like cocoa butter and whey protein from separating. In this case, it’s hidden inside the dark chocolate shavings listed in the Chocolate Ice Cream flavor. But here’s the issue: most brands in this price tier avoid soy-based additives due to allergen concerns and clean-label marketing standards—not MuscleSport.

So, What Is Soya Lecithins doing here? It’s a cost-effective workaround. It allows the chocolate shavings to hold their form, but it also raises an eyebrow when the product is marketed as “natural,” “grass-fed,” and “clean.” If your goal is a truly clean-label protein, this is a red flag hiding in the ingredient deck.

🫘 Are Soya Lecithins Bad For You?

If you’re asking, “Are soya lecithins bad for you?” you need to know: Soya lecithin is a soy-derived emulsifier used to blend ingredients and improve texture. But when paying premium prices for a so-called clean protein—why is a soy-based GMO ingredient used as an emulsifier?

According to MedicineNet’s breakdown of soy lecithin, the ingredient is generally considered safe for most people, even those with mild soy allergies. It may offer benefits like improved digestion, cholesterol support, and cell membrane function—but those benefits aren’t why it’s in your protein tub. It’s there for processing, not performance.

So, “Are Soya Lecithins Bad For You?” No, not inherently. But in a protein powder that markets itself as “clean,” it’s an ingredient that deserves scrutiny, especially when it’s coming from a company that won’t verify grass-fed sourcing, amino acid profiles, or third-party testing.

🫘 Soya Lecithins Allergy

Soya lecithins aren’t standard in most protein powders, so they raise eyebrows when they appear in MuscleSport Clean Whey’s Chocolate Shavings. This isn’t about fear-mongering. It’s about facts. If you have a soya lecithins allergy, even trace amounts can cause anything from skin irritation and nausea to severe reactions like anaphylaxis.

Here’s the problem: there’s no allergen disclosure on the Clean Whey label. No heads-up. No transparency. And if you’re dealing with a soya lecithins allergy, that silence is dangerous.

Want to understand how serious soy allergies can be? This article from Allergy & Asthma Specialists of North Florida breaks down the symptoms, risks, and hidden soy sources you must watch for—including lecithins.

🫘 Is Soya GMO-free?

Let’s cut through the marketing fluff. If you’re wondering, “Is Soya GMO-free?” The answer is rarely, especially in the U.S. According to the FDA’s official breakdown of GMO crops, 94% of all soybeans planted in the United States are genetically modified. That makes “GMO soy” the default unless proven otherwise.

So when MuscleSport Clean Whey includes soya lecithins in its formula—and doesn’t clarify whether they’re non-GMO, organic, or identity preserved—you already know the answer to Is Soya GMO-free? in this case. It’s not.

And here’s the final nail in the label: if a brand refuses to confirm sourcing, skips third-party testing, and stays silent when asked basic questions… do you think the soya lecithins in their “clean-label” protein are the rare 6%? I highly doubt it.

Is Soya GMO-free? Not unless the label says so—and MuscleSport’s doesn’t

🌍 Does Muscle Sport International Use Imported Protein?

Regarding transparency, Muscle Sport International doesn’t exactly roll out the welcome mat. I always ask the same question with every protein powder review: Can you provide an ingredient origin list? Muscle Sport International has ducked that question four times.

The only person I’ve managed to speak with? Someone in the marketing department. And their response was wildly surprising:

“These are not the typical questions that a customer would ask so may I ask why you would need such information?”

That’s not a red flag—it’s a bright red neon billboard.

Muscle Sport International promotes its protein as “grass-fed,” “clean,” and “premium” but refuses to provide basic sourcing transparency. There is no Certificate of Analysis, no amino acid profile, and no confirmation of where their whey comes from.

So, we are left with a pretty label and a high price tag. Based on industry patterns and labeling language, Muscle Sport International likely sources its whey from low-cost international distributors—potentially the same suppliers used by brands flagged for low purity or amino spiking.

Their grass-fed claims hold no water until Muscle Sport International provides verified sourcing or third-party lab documentation.

Ingredients List: 5.5 out of 10.
Muscle Sport USA advertises its Naturals Protein as “naturally flavored” with “no artificial dyes or sweeteners.” That’s not the problem. The issue with Muscle Sport USA is the complete lack of transparency behind those claims.

There is no amino acid profile, sourcing information, or third-party verification to back up anything on the label.

Yes, the Naturals formula looks clean on paper. But without proof, we’re left with one hard truth about Muscle Sport USA Naturals Protein: the ingredients are likely internationally sourced—and nothing about them is verified.

🔑 Nutrition Facts Muscle Sport Naturals Protein Powder, TL;DR

If you’re just looking at numbers, Strawberry and Vanilla Bean Ice Cream come out on top with an 86% protein percentage per scoop. Chocolate Ice Cream trails slightly at 80%. But numbers alone don’t tell the full story with Muscle Sports Protein Naturals.

There’s no amino acid profile. No leucine disclosure. No third-party testing. That makes Muscle Sports Protein Naturals a label-heavy product with no verified proof behind its protein claims. Buyer beware. What looks like a premium clean-label whey isolate might be marketing with no verified information on claims.

🥗 Nutrition Facts Muscle Sport Naturals Protein Powder

Here’s the full label breakdown for Chocolate Ice Cream, the flagship flavor of Muscle Sports Protein Naturals. While the macronutrient profile looks clean on paper—low sugar, moderate fiber, and 25g of protein—the issue isn’t the label. It’s the information that’s missing behind it.

Muscle Sports Protein Naturals has not released a leucine count, BCAA breakdown, or confirmed amino acid profile. I’ve requested it. Multiple times. No response. The result? A nutrition panel that looks premium but doesn’t offer premium verification.

🍗 Protein Percentage per Serving in Muscle Sport Nutrition Naturals

When evaluating Muscle Sport Nutrition Naturals, protein percentage tells you much about what you’re paying for. Based on the label, each Muscle Sport Protein lineup flavor claims 25 grams of protein—but scoop sizes vary.

Here’s how that breaks down:

Muscle Sport Protein Flavors	Protein per Serving	Scoop Size	Protein Percentage
Chocolate Ice Cream	25g	31.5	80%
Strawberry Ice Cream	25g	29g	86%
Vanilla  Bean Ice Cream	25	29	86%
Average Protein Percent Across All Flavors: 84%

The average protein percentage across all Muscle Sport Nutrition Naturals flavors is 84%. That’s solid—but without an amino acid profile or third-party testing, we can’t confirm if that protein is fully bioavailable or spiked with fillers. Muscle Sport Nutrition Naturals might look good on paper with an 84% protein average, but label math isn’t the same as verified quality. Without testing, you’re just trusting the scoop.

Nutrition Facts: 6.5 out of 10.
Muscle Sport Nutrition Naturals claims 25 grams of protein per scoop—but without an amino acid profile, we can’t verify that number. The listed 25 grams is likely inflated.

I’ve reached out to Muscle Sport Nutrition Naturals multiple times. No response. On paper, the label checks out. But when a brand refuses to share basic protein quality data, that’s a red flag. Transparency matters—and this review calls it out.

📋 Muscle Sport Grass Fed Whey Protein FAQ

Is MuscleSport Grass Fed Protein third-party tested?

No. There’s no evidence of third-party testing or cGMP verification for Muscle Sport Grass Fed Whey protein. I contacted the company directly and received no testing documentation—just silence.

Does MuscleSport Grass Fed Protein provide an amino acid profile?

No. There’s no amino acid profile on the label or the website, so you can’t verify the leucine or protein content.

Is Muscle Sport Grass Fed Whey protein certified grass-fed?

There is no third-party certification to confirm the grass-fed claims, and the company did not provide a Certificate of Analysis. 

Is there a California Prop 65 Warning?

Yes. The website includes a California Prop 65 warning, but the container does not. This inconsistency is troubling—especially for a product marketed as “clean” and “natural.”

Can I return MuscleSport Grass Fed Protein if I don’t like it?

You can return it within 15 days, but opened containers only qualify for store credit—not a full refund. Return shipping is also your responsibility.

Is MuscleSport Grass Fed Protein Non-GMO?

There’s no indication that MuscleSport Grass Fed Whey protein is non-GMO. The brand does not specify whether its soya lecithins or whey sourcing are GMO-free. According to the FDA, 94% of soybeans in the U.S. are genetically modified—so unless it says otherwise, assume you’re getting a GMO ingredient. That includes the soy-based emulsifier hiding in the chocolate shavings.

If a brand doesn’t confirm it and answer follow-up questions, that’s a red flag. A clean label? Not without proof.

Why doesn’t MuscleSport Grass Fed Protein list a leucine amount?

Amino acid profiles—especially leucine—are critical for judging protein quality. Despite repeated requests, Muscle Sport International has not disclosed leucine content or published a full amino acid profile for MuscleSport Grass Fed Whey Protein.

Is MuscleSport Grass Fed Protein processed with heat or cold methods?

The label on Muscle Sport Clean Whey claims it uses “cross-flow cold infused ultra micro filtrated” whey isolate. While that sounds impressive, most of those terms are unregulated and used for marketing. Cross-flow microfiltration is a recognized cold-processing method, which suggests the protein wasn’t heat-treated. However, MuscleSport provides no third-party verification or documentation to confirm this.

So, while the label implies cold-processing, we still have no proof that MuscleSport Grass Fed Whey Protein is truly filtered without heat—or that its bioavailability is preserved beyond the marketing language.

Can I verify if MuscleSport Grass Fed Whey Protein is sourced from U.S. dairy?

There is no proof that MuscleSport Grass Fed Whey Protein uses U.S.-sourced dairy. The company has not disclosed the country of origin, and there’s no sourcing breakdown or verification label on the packaging.

🏁 Muscle Sport Clean Whey Review – Final Thoughts

When you strip away the label claims, Muscle Sport Clean Whey Naturals is a protein powder with more red flags than proof points. It talks a big game with “grass-fed” and “clean label” marketing—but never shows its cards. No amino acid profile. No third-party testing. No sourcing disclosure. And when asked to verify even basic details, the company goes quiet. That’s not clean—it’s calculated.

Here are three things you should know about Muscle Sport Grass Fed Whey Protein Naturals before buying:

1. No Testing — Muscle Sport Grass Fed Whey Protein Naturals has no third-party testing or verification. There’s no Certificate of Analysis (CoA), no purity data, and no independent lab documentation—just a label with unverified claims.
2. No Transparency — I contacted the company multiple times asking for an amino acid profile and country of origin. Every request was read and never received a response: just silence.
3. No Proof of Grass-Fed — The label says “grass-fed,” but there’s no certification, sourcing confirmation, or traceability to support it. Without verified documentation, you’re left trusting marketing over facts.

✅ Is Muscle Sport Protein Good?

If you’re asking, “Is Muscle Sport Protein good?”—the short answer is no, not unless your only priority is taste. The flavor does match the price point, and the mixability is nearly flawless. But when it comes to what matters—transparency, amino acid quality, and sourcing—this one flops hard.

There’s no amino acid profile, third-party testing, or zero proof behind the “grass-fed” claim. I reached out multiple times and was ignored. The only response? A dismissive message from marketing questioning why I even wanted this information.

So, who should buy Muscle Sport Protein?

If you want a protein shake that tastes like dessert and doesn’t care what’s in it—this is for you. But at $2.00 a scoop with zero verification, you might as well eat a candy bar or grab a protein bar off the shelf. At least you’ll know what you’re getting.
