Is The Bulk Protein Company a good brand?
The Bulk Protein Company sells mainly in large tubs aimed at people trying to gain weight, so several products here are deliberately carbohydrate-heavy. Read the protein per 100g column before comparing: a mass gainer at 22g protein per 100g is doing a different job from a whey at 80g, and it will look expensive per 25g of protein even when the tub is cheap. WheyWise tracks 2 of their products across 1 product types. The cheapest works out to £0.23 per 25g of protein on Vegan Gainz 4kg, with the range spanning £0.23 to £0.93 across 1 UK retailers.

Frequently Asked Questions
How much does The Bulk Protein Company protein cost in the UK?
Their protein currently ranges from £0.23 to £0.93 per 25g of protein across the UK retailers we track. The cheapest right now is Vegan Gainz 4kg.
Is Serious Gainz a protein powder or a weight gainer?
It is a weight gainer, which means most of the powder is carbohydrate rather than protein. That is the point of the product, but it does mean cost per 25g of protein is the wrong yardstick if what you want is calories. The table above shows both the protein density and the price so you can judge it on the right basis.

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.
