THE Pre Workout Gel, Tropical, 12 sachets

£12.99 for 12 sachets at Myprotein. 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 100 mg£98.41One 100 mg dose is our comparison unit for thiamine (vitamin B1). It is not a recommendation.
A day£98.41
A week£688.86
A month£2952.27
A year£35919.32

At one 100 mg dose a day, this pack lasts under a day. A month is 30 days, so twelve of them is not quite a year.
