Impact Whey Protein Powder, Banana
£107.49 for 120 servings at Myprotein. That works out at £1.12 per 25 g protein, which ranks it 15th of the 94 whey protein blend products we price across 5 UK retailers.
At one 25 g dose a day, this pack lasts 3 months. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- In the pack: 120 × 20 g = 2,400 g
- £107.49 ÷ 2,400 g × 25 g = £1.12 per 25 g protein
- A week £1.12 × 7 = £7.84 · a month × 30 = £33.59 · a year × 365 = £408.69
- Amount per serving: stated on the label.
