How we worked it out

Protein powder

  • Servings: 1065 ÷ 42.5 per serving = 25.1
  • In the pack: 25.1 × 10.8 g = 270.6 g
  • £39.99 ÷ 270.6 g × 25 g = £3.69 per 25 g protein
  • A week £3.69 × 7 = £25.86 · a month × 30 = £110.82 · a year × 365 = £1348.34
  • Amount per serving: stated on the label.

BCAA

  • Servings: 1065 ÷ 42.5 per serving = 25.1
  • In the pack: 25.1 × 2.5 g = 62.6 g
  • £39.99 ÷ 62.6 g × 5 g = £3.19 per 5 g
  • A week £3.19 × 7 = £22.34 · a month × 30 = £95.75 · a year × 365 = £1164.97
  • Amount per serving: stated on the label.

HMB

  • Servings: 1065 ÷ 42.5 per serving = 25.1
  • In the pack: 25.1 × 800 mg = 20 g
  • £39.99 ÷ 20 g × 3 g = £5.98 per 3 g calcium HMB
  • A week £5.98 × 7 = £41.89 · a month × 30 = £179.53 · a year × 365 = £2184.31
  • Amount per serving: estimated from the compound weight using our conversion factor.

L-Glutamine

  • Servings: 1065 ÷ 42.5 per serving = 25.1
  • In the pack: 25.1 × 800 mg = 20 g
  • £39.99 ÷ 20 g × 5 g = £9.97 per 5 g
  • A week £9.97 × 7 = £69.82 · a month × 30 = £299.22 · a year × 365 = £3640.52
  • Amount per serving: stated on the label.
