Check out all of my unbiased protein reviews.
How We Review Protein Powders
At JKremmer Fitness, every protein powder gets the same audit: 1) Label type and FDA compliance, 2) percent protein per serving, 3) full amino acid profile or refusal to provide one, 4) third-part testing claims that can be verified, 5) heavy metals or Prop 65 exposure language, and 6) buyer value based on price per gram of actual protein and transparency. That’s how we keep these protein reviews unbiased and repeatable.
- Third-party testing
- Amino spiking detection
- Label compliance (Nutrition Facts vs Supplement Facts)
- Percent protein per serving
- Mixability
- Transparency
Latest Unbiased Protein Powder Review
Here’s my latest unbiased protein powder reviews that I’ve released.
- Is Rule 1 Protein Safe? A Clear Look at What You’re Actually Drinking
Is Rule 1 Protein Safe? Are Rule 1 proteins safe? Without third-party protein testing or complete disclosure of heavy metal… Read more: Is Rule 1 Protein Safe? A Clear Look at What You’re Actually Drinking - Rival Nutrition vs Optimum Nutrition: Which Whey Protein Actually Delivers What It Claims?
The Rival Nutrition vs Optimum Nutrition comparison comes down to one question: do you value flavor-first convenience or measurable protein transparency? Rival Naturally Flavored Whey delivers clean sweetness and fast mixability but hides its amino profile, leucine, and protein verification. Optimum Nutrition Gold Standard Whey offers a published amino map and clearer leucine data, even after its recent reformulation. Both work as daily shakes, but only one gives buyers something concrete to trust. - Is Rival Nutrition Good? The Truth No One Tells You About Their Whey Protein
Is Rival Nutrition Good? That depends on what you value. If you want a clean-tasting protein that mixes fast and avoids artificial sweeteners, Rival Nutrition delivers. But if you judge a whey by amino transparency, leucine disclosure, or third-party protein testing, the brand comes up short. The flavor is strong, the mixability is excellent, and the label is simple—but the missing amino data and lack of verification make Rival better for casual users than serious lifters. - Rival Nutrition Whey Review: Testing the Naturally Flavored Rival Whey Protein Powder
This review breaks down Rival Nutrition from the inside out—what the label promises, what the numbers actually show, and where the transparency falls short. You’ll see how Rival Nutrition markets a clean, naturally flavored whey while withholding the amino data and verification modern buyers expect. If you’re deciding whether Rival Nutrition deserves a spot in your daily routine, this review gives you the clarity the brand doesn’t. - Swolverine Whey Protein Isolate Review: Mixability, Flavor, and Protein Integrity Examined
This Swolverine Protein review pulls back the curtain on a label built on marketing, not proof. While Swolverine Protein claims 26g of “pure protein” from grass-fed whey, it provides no amino acid profile, no leucine data, and no current third-party testing to verify quality. With a Prop 65 warning now on the bag and near $3 per serving, Swolverine Protein sells polish—but skips the evidence serious athletes need to trust it.

FAQ: Protein Review Standards
An unbiased review starts with data, not sponsorships. Every product here is purchased out-of-pocket and scored against the same metrics–label accuracy, amino acid disclosure, third party testing, protein per serving, Prop 65 status, and value per gram. No free tubs, no “influencer discounts,” and no brand edits.
Because a label’s protein number doesn’t tell the whole story. The leucine yield determines real muscle protein synthesis potential, and missing or inflated amino tables often hint at amino spiking. If a brand refuses to provide the amino profile, it’s listed as a transparency failure, earning a 1 out of 10 score.
Yes — and many don’t Under FDA 21 CFR 101.36(b)(2)(i), any Supplement Facts panel that includes protein should also list a %DV unless the protein quality is untested. When brands skip that number, it signals either missing PDCAAS data or poor label compliance.
Absolutely! Informed Protein, Informed Choice, and Labdoor verification confirm that a brand’s claims match lab results and the product is screened for contaminants or it’s protein quality. Without those seals, “lab tested” is just marketing copy–anyone can print that.
