Impact Whey Isolate Milkshake, Unflavoured, 990 g
£43.99 for 990 g at Myprotein. That works out at £1.41 per 25 g protein, which ranks it 50th of the 94 whey protein blend products we price across 5 UK retailers.
At one 25 g dose a day, this pack lasts 31 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 990 ÷ 33 per serving = 30
- In the pack: 30 × 26 g = 780 g
- £43.99 ÷ 780 g × 25 g = £1.41 per 25 g protein
- A week £1.41 × 7 = £9.87 · a month × 30 = £42.30 · a year × 365 = £514.63
- Amount per serving: stated on the label.
