On the bench
// 5 whey proteins + 2 non-whey (1 vegan blend, 1 soy/milk blend). One sealed batch each, June–July 2026.
What the labs found
Every batch was authentic - no amino spiking, no collagen cutting, and all heavy metals within UK/EU limits. The industry's dirtiest tricks weren't in these tubs.
Measured protein ranged from meeting the claim… to landing ~14% under it. Three of the seven fell 10%+ short of the number printed on the tub.
The #1 quality whey is not the cheapest - and the best value per gram of real, measured protein isn't the brand most people would guess.
Whey delivered roughly 2–3× the leucine per serving of the plant options - the amino acid most tied to muscle-protein synthesis.
Prices swing month to month - some tubs vary by nearly £20/kg across the year. The report includes "good buy below" price thresholds.
