At one 25 g dose a day, this pack lasts 9 days. A month is 30 days, so twelve of them is not quite a year.
How we worked it out
- Servings: 300 ÷ 31 per serving = 9.7
- In the pack: 9.7 × 24 g = 232.3 g
- £24.00 ÷ 232.3 g × 25 g = £2.58 per 25 g protein
- A week £2.58 × 7 = £18.08 · a month × 30 = £77.50 · a year × 365 = £942.92
