Plain talk on peptides.

Honest, judgement-free information about peptides — what they do, how they’re taken, what to expect, and what the actual risks are. People are going to use them either way. We’d rather they have the facts.

What this site is

A plain-English guide to every peptide on the market.

Peptides are short chains of amino acids. Some are well-understood, approved medicines. Many are research compounds with growing community use but very little official information — and even less honest information.

Just Peptides exists because people are already buying and using these compounds. There’s no shortage of marketing. There’s very little harm-reduction information that isn’t either dismissive (“don’t do it”) or selling something. So we wrote our own.

We are inspired by the UK government’s Talk To Frank site — a frank, accurate, non-judgemental drug information service. We’re trying to do the same thing for peptides.

We’re not your doctor.

This is information, not medical advice. If you are taking a peptide for a health condition, do it under medical supervision. If you can’t or won’t, at least know the facts.

Dosage. How to take it. How to store, reconstitute and check it. What to expect and over what timeframe. Side effects, risks, potential gains. One page per peptide.
