Methodology

How we rank every bag.

Independent, transparent, and updated weekly. Here's what goes into each score.

01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein quality, not just %
Protein %, leucine and digestibility feed the Performance score. A 90% isolate and a 90% vegan blend are not the same.
03
Clean-label audit
Ingredient count, artificial sweeteners, added sugars, third-party certifications. 0 to 100 score.
04
Social and review signals
Weekly purchase volume and weighted review scores surface what people actually re-buy, not just what ranks on search.
