£51.13 for 906 g at Healf. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.

What it really costs, per 25 g protein£2.03One 25 g dose is our comparison unit for protein powder. It is not a recommendation.
A day£2.03
A week£14.20
A month£60.87
A year£740.57

At one 25 g dose a day, this pack lasts 25 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

  • Servings: 906 ÷ 30.2 per serving = 30
  • In the pack: 30 × 21 g = 630 g
  • £51.13 ÷ 630 g × 25 g = £2.03 per 25 g protein
  • A week £2.03 × 7 = £14.20 · a month × 30 = £60.87 · a year × 365 = £740.57
  • Amount per serving: stated on the label.

The standard dose is a comparison unit, not a recommendation. Always confirm the price on the retailer's site. How we compare everything.
