Whey Protein 360 600g Banana Smooth
£15.99 for 600 g at Protein Works. That works out at £1.00 per 25 g protein, which ranks it 33rd of the 160 whey protein concentrate products we price across 8 UK retailers.
At one 25 g dose a day, this pack lasts 16 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 600 ÷ 30 per serving = 20
- In the pack: 20 × 20 g = 400 g
- £15.99 ÷ 400 g × 25 g = 99.9p per 25 g protein
- A week 99.9p × 7 = £7.00 · a month × 30 = £29.98 · a year × 365 = £364.77
- Amount per serving: stated on the label.
