Is Myprotein a good brand?

Myprotein is the default choice when value per gram is what matters most. Impact Whey is the UK price benchmark, and Impact Whey Elite is the Informed Sport batch-tested variant for competing athletes. The range is the broadest in the country: whey concentrate, isolate, vegan, casein, mass gainer, pre-workout, all from one checkout. WheyWise tracks 23 Myprotein products across 7 categories. The cheapest right now is £0.41 per 25g of protein on Impact Soy Protein 5kg, ranging up to £2.20. Check live discount status before reordering: paying RRP on Myprotein is almost always avoidable.

Frequently Asked Questions

How much does Myprotein cost per 25g of protein?

Myprotein currently ranges from £0.41 to £2.20 per 25g of protein across the products we track. The cheapest right now is Impact Soy Protein 5kg. Prices drop significantly during Myprotein's regular flash sales, which run every few weeks.

Is Myprotein Informed Sport certified?

Myprotein's Impact Whey Elite range is Informed Sport batch-tested and intended for athletes subject to drug testing. Standard Impact Whey is not automatically certified. Check the specific product listing for current certification status before buying.

Is Myprotein cheaper than Bulk?

It depends on timing. Myprotein relies on frequent discount cycles, so headline prices drop sharply during sales. Bulk's standard pricing is often competitive without needing a code, and the subscription model adds a steady discount. Compare live prices in the table above.

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.
