We don't make any of this. We just tell you the truth about it.

Price per 100 g on every product, so 40 brands can be compared on one axis. Certification that links to the certifier's own register, not a badge we drew. Stock numbers that are the real ones.

Free delivery over £45. Order by 4pm and it goes today. 60 days to send it back, opened or not.

What a shop can honestly tell you

What it costs per 100 g
On every card and every bulk tier, so a 500 g tub and a 2.5 kg bag from different brands can be compared without arithmetic.
Who tested the batch
Informed Sport and NSF certification, linked to the certifier's database so you check it somewhere that isn't this website.
Whether it is actually here
A real number from the warehouse, and a date when it is not.

A curated shop, not medical advice. Nothing here is a recommendation to take anything.

Tested and certified

10 of the products on this page carry third-party batch certification. Every certificate number links to the testing body's own register.

Sixty days to send it back, opened or not

A pre-workout takes a fortnight to judge. Every other UK supplement shop gives you 14 to 30 days and only takes it back sealed, which makes the policy unusable for the thing returns exist for. Start it in your account and we email a prepaid label. This sits on top of the 14-day right the Consumer Contracts Regulations already give you.
