How we worked it out

L-Theanine

  • Servings: 600 ÷ 20 per serving = 30
  • In the pack: 30 × 250 mg = 7.5 g
  • £19.99 ÷ 7.5 g × 200 mg = 53.3p per 200 mg
  • A week 53.3p × 7 = £3.73 · a month × 30 = £15.99 · a year × 365 = £194.57
  • Amount per serving: stated on the label.

Beta-alanine

  • Servings: 600 ÷ 20 per serving = 30
  • In the pack: 30 × 3.5 g = 105 g
  • £19.99 ÷ 105 g × 3.2 g = 60.9p per 3.2 g
  • A week 60.9p × 7 = £4.26 · a month × 30 = £18.28 · a year × 365 = £222.36
  • Amount per serving: stated on the label.

Caffeine

  • Servings: 600 ÷ 20 per serving = 30
  • In the pack: 30 × 300 mg = 9 g

  • Amount per serving: stated on the label.

L-Arginine

  • Servings: 600 ÷ 20 per serving = 30
  • In the pack: 30 × 4 g = 120 g
  • £19.99 ÷ 120 g × 3 g = 50p per 3 g
  • A week 50p × 7 = £3.50 · a month × 30 = £14.99 · a year × 365 = £182.41
