Myprotein Impact Whey Protein Powder | 22g Premium is one of 45 protein powder products on our shelf, compared on what buyers rated it, how many of them there were, and what it costs today. Here is how the maker describes it: Packed with 22g of high-quality whey protein per serving, Impact Whey Protein fuels muscle growth, maintenance, and recovery, helping you stay one step ahead of your goals. With Informed Choice certification, every scoop is independently tested for purity, giving athletes confidence in every sip. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.4 out of 5 across 8,000 ratings. How that compares with the rest of the shelf is below.
Taken from the wording on the listing itself and the price we track, not from a brand claim about value. How we rank →
The typical protein powder product on our shelf scores 4.4 out of 5, measured across 45 rated products. This one comes in at 4.4. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.
That score rests on 8,000 ratings. The median for this shelf is 474. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the middle third of a shelf running from £14.66 to £170, with the midpoint around £40.00. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
