The short answer
For whey, Nutrimuscle. For creatine, Myprotein on promotion. Nutrimuscle’s native whey concentrate works out at 41.23 EUR per kilo of protein in the 4 kg tub, 24% less than Myprotein’s Impact Whey even when discounted. On creatine it is the other way round: 2.80 EUR per 100 g at Myprotein on promotion, against 9.99 EUR at Nutrimuscle. On customer ratings, Nutrimuscle scores higher (4.5 against 4.1), while Myprotein replies more often to negative reviews.
What our price checks found
| Product | Nutrimuscle | Myprotein | Cheaper |
|---|---|---|---|
| Whey, large size | 41.23 EUR per kilo of protein (Whey Native, 4 kg, 80%) | 54.01 EUR per kilo of protein (Impact Whey, 3.6 kg, 72%, on promotion) | Nutrimuscle, 24% less |
| Whey, small size | 47.44 EUR (1 kg) | 60.17 EUR on promotion, 92.58 EUR at the crossed-out price (900 g) | Nutrimuscle, 21% less |
| Creatine | 9.99 EUR per 100 g (Creapure, 350 g) | 2.80 EUR per 100 g (1 kg, on promotion); 5.00 EUR at the crossed-out price for the 500 g | Myprotein, 50 to 72% less |
One each, and the gaps matter. At 25 g of protein a day, whey costs 376 EUR a year from Nutrimuscle in the 4 kg tub against 493 EUR from Myprotein in the discounted 3.6 kg. At 3 g of creatine a day, it is 31 EUR a year from Myprotein on promotion against 109 EUR from Nutrimuscle.
Where Nutrimuscle wins
The whey, on both content and price. Its Whey Native contains 80% protein, against 72% for Myprotein’s vanilla Impact Whey, which also contains an emulsifier (soya and sunflower lecithin) and sucralose according to its ingredients list. More protein per gram, and a cheaper gram of protein: it is the best concentrate in our whey comparison.
A stable price. The Nutrimuscle prices we recorded are standard prices. Myprotein’s only make sense on promotion: without one, its 900 g Impact Whey goes up to 92.58 EUR per kilo of protein, almost double Nutrimuscle.
Where Myprotein wins
The creatine, during a promotion. At 2.80 EUR per 100 g in the 1 kg bag, it is the cheapest creatine in all our price checks, and even at the crossed-out price (5.00 EUR per 100 g in the 500 g size) it stays half the price of Nutrimuscle’s. One caveat: Nutrimuscle shows the Creapure label, which we did not find at Myprotein. If that label matters to you, check the product page.
The choice. Flavours, plant-based versions, sizes from 450 g to 3.6 kg: Myprotein’s range is far wider.
What customers say
| Indicator | Nutrimuscle | Myprotein |
|---|---|---|
| Average rating | 4.5 / 5 | 4.1 / 5 |
| Number of reviews | 29,695 | 32,818 |
| 5 stars | 77% | 65% |
| 1 star | 6% | 10% |
| Replies to negative reviews | 69%, within two weeks | 99% |
The two review volumes are comparable, which makes the comparison solid: Nutrimuscle is rated higher and has fewer one-star reviews, while Myprotein replies to almost all unhappy customers. For Myprotein, the criticisms mostly concern orders and prices, and the presence of sucralose and emulsifiers.
Which to choose, in practice
Buy your whey from Nutrimuscle, in the 4 kg tub if you use it every day: more protein per gram, cheaper, and no need to wait for a promotion.
Buy your creatine from Myprotein, during a promotion, in the 1 kg bag. If you are an athlete subject to drug testing or the Creapure label matters to you, look at our creatine comparison instead.

How we put this page together
We have not tested these products and we do not claim to. Prices were taken from the two brands’ official pages, on the dates shown under each table, then converted to a per-kilo-of-protein or per-100 g-of-creatine basis. Customer reviews come from Trustpilot: they measure the buying experience, not how well a supplement works. Prices change, Myprotein’s especially: check the current price before you buy.
