  • A week £1.66 × 7 = £11.63 · a month × 30 = £49.85 · a year × 365 = £606.56
  • Amount per serving: stated on the label.

BCAA

  • Servings: 908 ÷ 35 per serving = 25.9
  • In the pack: 25.9 × 4.8 g = 124.5 g
  • £36.99 ÷ 124.5 g × 5 g = £1.49 per 5 g
  • A week £1.49 × 7 = £10.40 · a month × 30 = £44.56 · a year × 365 = £542.11
