What it is

Not a peptide at all, strictly speaking. It is a coenzyme — a helper molecule cells use constantly.

Turns up in cell-energy research, and is usually sold alongside peptides.

Worth knowing it is a different kind of molecule from everything else on this list.

Advertising disclosure We earn a commission if you buy through these links, at no extra cost to you. It does not change a tier, a vote or a row on any scorecard. Tiers come from a recorded committee vote; scorecard rows come from what a seller publishes and what we could check.

Sold for laboratory research only. Not approved for people to take. Listing a seller is not a recommendation to buy or to use anything.

This sheet describes, it does not recommend. Nothing on it says this compound does anything for anyone. It is not approved for people to take. Talk to a doctor about your health.
