How we worked it out

L-Citrulline

  • In the pack: 18 × 4 g = 72 g
  • £13.49 ÷ 72 g × 3 g = 56.2p per 3 g citrulline malate
  • A week 56.2p × 7 = £3.93 · a month × 30 = £16.86 · a year × 365 = £205.16
  • Amount per serving: estimated from the compound weight using our conversion factor.

Beta-alanine

  • In the pack: 18 × 1.8 g = 32.4 g
  • £13.49 ÷ 32.4 g × 3.2 g = £1.33 per 3.2 g
  • A week £1.33 × 7 = £9.33 · a month × 30 = £39.97 · a year × 365 = £486.31
  • Amount per serving: stated on the label.

Caffeine

  • In the pack: 18 × 147 mg = 2.65 g
  • £13.49 ÷ 2.65 g × 200 mg = £1.02 per 200 mg

  • Amount per serving: stated on the label.
