Is Mutant a good brand?

Mutant is best known in the UK for its mass gainers, and the catalogue reflects that: Mutant Mass, Mass Dual Chamber and Mass Extreme 2500 sit alongside the straight protein options. On the protein side, Mutant Whey is the everyday blend, with Iso Surge and Hardcore Iso as the leaner isolates. If you are eating to gain weight, the gainers are the point of the brand; if you are not, ignore them, because they carry far more carbohydrate per scoop and will read as poor value on a cost-per-protein basis. WheyWise tracks 2 Mutant products across 1 types, from £1.34 per 25g of protein on Mass Dual Chamber 2.72kg up to £1.63, across 1 UK retailers.

Frequently Asked Questions

How much does Mutant protein cost in the UK?

Mutant currently ranges from £1.34 to £1.63 per 25g of protein across the UK retailers we track. The cheapest right now is Mass Dual Chamber 2.72kg.

Is Mutant Mass a protein powder?

No, it is a mass gainer. Most of each serving is carbohydrate, with protein making up a smaller share, because it is designed to add calories rather than protein alone. That is why gainers look expensive per 25g of protein in the table above. If protein is what you are buying, compare Mutant Whey, Iso Surge and Hardcore Iso instead.

What is the difference between Mutant Whey and Iso Surge?

Mutant Whey is a blend built around concentrate, so it costs less per tub but carries more carbohydrate and fat. Iso Surge is an isolate, filtered so more of each scoop is protein and less is lactose. Rank them on cost per 25g rather than tub price, since the isolate delivers more protein per scoop.

Methodology

How we rank every bag.

Independent and transparent, with every price shown alongside the date it was checked. 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.
