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 27 Myprotein products across 7 categories. The cheapest right now is £0.34 per 25g of protein on Impact Pea Protein 2.88kg, ranging up to £2.66. Check the 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 £0.34 to £2.66 per 25g of protein across the products we track. The cheapest right now is Impact Pea Protein 2.88kg. 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 the prices in the table above.

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 density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Every price carries its date
Prices come from the retailer's own listing, never an RRP, and each one is shown with the day it was last checked so you can judge how current it is.
04
No sponsored placements
Rank order is cost per 25g of protein. Some outbound links earn commission; none of them buy a position in the table.
