How the numbers stack up against the price

Warrior Whey and Mutant Whey are two budget whey concentrates popular with UK gym-goers, but their protein content tells very different stories. Warrior Whey delivers 71g of protein per 100g of powder - a strong number that puts it alongside established value leaders like Myprotein Impact Whey and Bulk Pure Whey. Mutant Whey manages just 59g per 100g, meaning roughly 40% of the powder you consume is filler rather than protein. Both products target the same budget-conscious buyer, but the gap in protein density is one of the largest we have seen in a head-to-head whey concentrate comparison.

Out of 5

Mutant Whey2.6

Warrior Whey wins this one decisively.

The 12g-per-100g protein advantage translates to meaningfully more protein per scoop, per tub, and per pound spent. Even if Mutant Whey appears cheaper on the sticker price, the lower protein concentration means you need to use more powder per serving to hit the same protein target, so the tub runs out faster and the real cost per gram of protein is higher. Warrior Whey also benefits from direct UK availability via teamwarrior.com and a wider flavour range. For UK buyers after a budget whey concentrate, Warrior Whey is the clear choice on the numbers.
