Insanity®, Cherry bomb, 250 g

£34.99 for 250 g at Bio-Synergy. It carries more than one active ingredient, so it is not ranked against single-ingredient products. Each price below counts one ingredient only.

What it really costs, per 5 g£3.50One 5 g dose is our comparison unit for creatine. It is not a recommendation.
A day£3.50
A week£24.49
A month£104.97

At one 5 g dose a day, this pack lasts 10 days. A month is 30 days, so twelve of them is not quite a year.

How we worked it out

Creatine

  • In the pack: 50 × 1 g = 50 g
  • £34.99 ÷ 50 g × 5 g = £3.50 per 5 g
  • A week £3.50 × 7 = £24.49 · a month × 30 = £104.97 · a year × 365 = £1277.14
  • Amount per serving: stated on the label.

Beta-alanine

  • In the pack: 50 × 500 mg = 25 g
  • £34.99 ÷ 25 g × 3.2 g = £4.48 per 3.2 g
  • A week £4.48 × 7 = £31.35 · a month × 30 = £134.36 · a year × 365 = £1634.73
  • Amount per serving: stated on the label.

Caffeine

  • In the pack: 50 × 200 mg = 10 g
  • £34.99 ÷ 10 g × 200 mg = 70p per 200 mg
  • A week 70p × 7 = £4.90 · a month × 30 = £20.99 · a year × 365 = £255.43
  • Amount per serving: stated on the label.

L-Arginine

  • In the pack: 50 × 500 mg = 25 g
  • £34.99 ÷ 25 g × 3 g = £4.20 per 3 g
  • A week £4.20 × 7 = £29.39 · a month × 30 = £125.96 · a year × 365 = £1532.56
  • Amount per serving: stated on the label.
