- Concentrate, not isolate

The cleanest gym-bag whey at a fair price. Stevia instead of sucralose; flavor lands in the middle.
Pros
- NSF Certified for Sport
- Grass-fed + organic
- Stevia-sweetened
Cons
- Slight stevia aftertaste
- Some clumping in cold water
3.Taste: Optimum Nutrition Still Wins Blind
Each powder mixed in 8 oz of cold water with a standard BlenderBottle. Three tasters scored chocolate and vanilla blind from 1–10. Chocolate averages: ON 9.4, Momentous 8.9, Garden 7.2, Thorne 7.5. Vanilla averages: ON 9.0, Momentous 8.5, Thorne 7.5, Garden 6.8. Optimum Nutrition's flavor is engineered with artificial sweeteners — and it shows.
"Momentous mixes perfectly and doesn't taste like chalk or chemicals. Worth every extra cent if you're serious about what you put in your body."
4.Ingredient Quality: NSF Certified For Sport Is The Bar
NSF Certified for Sport is the strictest third-party purity certification — it tests for 280+ banned substances and confirms what's on the label is in the tub. Three of our four finalists hold it (Momentous, Thorne, Garden of Life). Optimum Nutrition holds Informed Choice, a lesser-but-real certification. All four are real protein; only Momentous and Thorne are also free of artificial sweeteners.
5.Mixability: ON & Momentous Are Spotless
Each powder shaken 30 seconds in cold water, photographed against backlight. Optimum Nutrition: zero clumps. Momentous: zero clumps. Thorne: minor surface foam. Garden of Life: 4–6 visible micro-clumps and required a second shake.
6.Price: Cost Per 20g Of Protein
Cost per 20g of protein: Optimum Nutrition $0.87, Garden of Life $1.67, Thorne $2.14, Momentous $2.50. Momentous costs nearly 3x ON per gram — the premium buys ingredient quality, not extra protein.
7.The Winner: Momentous Whey Protein
After 30+ hours across 12 protein powders, Momentous Whey Protein wins on ingredient quality, third-party testing, and clean-label integrity — the metrics that matter if you're using protein daily for years. Optimum Nutrition is the right pick if taste and price are your only criteria; Thorne for clinical-grade purity at lower cost.
"I tested 12 powders. Momentous is what I scoop every morning. Worth the premium for the label alone."
