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.
- Heart and Soil vs Promix — Which Protein Powder Is Better?
Heart and Soil vs Promix compares two grass-fed whey proteins that look similar on the label but differ in execution. This breakdown cuts through marketing to examine protein integrity, testing transparency, amino acid credibility, pricing, and daily-use risk so you can decide which brand actually earns your trust. - PEScience vs Syntha-6 Protein: Protein Supplement or Meal Replacement?
PEScience vs Syntha-6 Protein isn’t a battle of taste—it’s a clash of purpose. Syntha-6 behaves like real food, delivering calories, fiber, and fullness. PEScience drinks lighter, fits better into muscle-focused routines, and prioritizes flavor over satiety. Same price tier, very different jobs. - Optimum Nutrition Gold Standard Review: Same Protein, Different Formula?

Swolverine vs Momentous compares two premium whey isolates marketed to athletes. Swolverine delivers more protein per scoop and elite mixability but lacks amino disclosure and clear verification. Momentous provides lower protein density, yet offers disclosed leucine data, NSF Certified for Sport screening, and greater transparency—making it the safer, lower-regret purchase for most buyers. - Swolverine vs Transparent Labs — Which Protein Delivers Real Value?
Swolverine vs Transparent Labs comes down to proof. One offers smooth texture and a minimalist label, the other delivers verified amino data, stronger testing, and better value per scoop. If you care more about documented protein quality than branding polish, Transparent Labs is the clear choice.

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.
