With tiramisu, cinnamon danish and blueberry cheesecake among its 40-plus flavours, I could have my cake and drink it with Myprotein Impact Whey Powder.
Men’s Fitness verdict
Myprotein’s powder is the cheapest on test per serving. It’s low in calories, fats and sugars, and although it doesn’t mix too well, it’s available in a dizzying array of flavors and sizes.- Low in calories
- Good amount of BCCAs
- Great value
- A bit too sweet
- Need to re-shake while drinking
- Pouch is tricky to reseal
Also known for its range of workout clothing, it’s easy to forget Myprotein literary made its name making the best protein powders and bars. Its Impact Whey Powder shake is 80% protein concentrate. Each 25g serving will therefore give you 20g of protein to feed your muscle development. The shake also contains 4.5g branch chain amino acids (BCAAs), including 2.5g leucine.
Why you can trust Men’s Fitness
Men’s Fitness has had its finger on the pulse of the healthy lifestyle scene since 2001. That means we’ve got more than two decades of experience in the industry and have built up connections with top professionals. As such, we only offer insight and advice from those who know best – and who have the credentials to prove it. In this case, we’ve teamed up with pro nutritionist Rob Hobson, who conducted the testing, and performance coach Matt Lovell, for some insight into key ingredients. Find out more about how we test.
Myprotein Impact Whey Powder in use
This powder is low in fat and sugar and uses sucralose and acesulfane K to sweeten. I found the shake to be a little too sweet, but there are a number of flavors that are sweetened with stevia, which should dial the sweetness back.
It’s worth noting that its minimal ingredient list does contain soy and artificial flavours, which may not appeal to people looking for something less synthetic.
A serving of the Myprotein shake contains 103 calories when mixed with water, which is the second lowest on test. There’s just 1.9g of fats and 1g of sugars per serving too. I liked that the product mixes fairly well, but it isn’t completely smooth, and I had to shake it a few times while drinking it to stop some sediment from settling.
Sizes and availability
The resealable pouches are available in five sizes, from 250g to 5kg. The 1kg pouch works out at £1 a serving, which is decent value, with the 5kg pouch better still. You can only get the Impact Whey Protein powder from myprotein.com and you’ll need to pay postage under £45 but delivery is fairly quick.
The packaging is fiddly to re-seal, which I found a bit irritating, so you might want to decant the mixture into a sealable container. The only other issue you might have is choosing which flavor to try. There are more than 40 to choose from, including unusual and exotic flavours ranging from speculoos and jelly bean (buttered popcorn) to peach tea, mango and tiramisu.

How we test the best protein powders
Registered nutritionist (AFN) and sports nutritionist (SENr) Rob Hobson only tested chocolate-flavoured powders to provide consistency in his reviews. He judged them on their taste, texture, solubility and nutritional effectiveness, as well as cost per serving and availability. He also took into account the variety of flavours and any recyclable packaging.
