Impact Diet Whey 1kg Chocolate
£30.49 for 1 kg at Myprotein. That works out at £1.27 per 25 g protein, which ranks it 147th of the 160 whey protein concentrate products we price across 8 UK retailers.
At one 25 g dose a day, this pack lasts 24 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 1000 ÷ 60 per serving = 16.7
- In the pack: 16.7 × 36 g = 600 g
- £30.49 ÷ 600 g × 25 g = £1.27 per 25 g protein
- A week £1.27 × 7 = £8.89 · a month × 30 = £38.11 · a year × 365 = £463.70
- Amount per serving: stated on the label.
