How we worked it out

L-Citrulline

  • In the pack: 40 × 3 g = 120 g
  • £19.99 ÷ 120 g × 3 g = 50p per 3 g citrulline malate
  • A week 50p × 7 = £3.50 · a month × 30 = £14.99 · a year × 365 = £182.41
  • Amount per serving: estimated from the compound weight using our conversion factor.

Beta-alanine

  • In the pack: 40 × 1.6 g = 64 g
  • £19.99 ÷ 64 g × 3.2 g = 99.9p per 3.2 g
  • A week 99.9p × 7 = £7.00 · a month × 30 = £29.98 · a year × 365 = £364.82
  • Amount per serving: stated on the label.

Betaine (TMG)

  • In the pack: 40 × 1 g = 40 g
  • £19.99 ÷ 40 g × 2.5 g = £1.25 per 2.5 g
  • A week £1.25 × 7 = £8.75 · a month × 30 = £37.48 · a year × 365 = £456.02
  • Amount per serving: stated on the label.

Caffeine

  • In the pack: 40 × 150.5 mg = 6.02 g
  • £19.99 ÷ 6.02 g × 200 mg = 66.4p per 200 mg
  • A week 66.4p × 7 = £4.65 · a month × 30 = £19.92 · a year × 365 = £242.40
  • Amount per serving: stated on the label.

L-Arginine

  • In the pack: 40 × 1.5 g = 60 g
  • £19.99 ÷ 60 g × 3 g = 99.9p per 3 g
  • A week 99.9p × 7 = £7.00 · a month × 30 = £29.98 · a year × 365 = £364.82
  • Amount per serving: stated on the label.

L-Tyrosine

  • In the pack: 40 × 1 g = 40 g
  • £19.99 ÷ 40 g × 500 mg = 25p per 500 mg
  • A week 25p × 7 = £1.75 · a month × 30 = £7.50 · a year × 365 = £91.20
  • Amount per serving: stated on the label.
