Are peptides legal? It depends on the compound and the country.
A peptide is not legal or illegal as a class. For each one there are three separate questions: is it an approved medicine, can you obtain it lawfully, and is it allowed in sport. This page answers all three for ten common peptides, names the regulator behind every answer, and tracks what the FDA and DEA publish as it happens.
Which country are you asking about?
We list a country only once we have checked every compound against that country's own drug database, so nothing here is a shrug. The United Kingdom and Australia are not yet listed because their registers cannot be read automatically, and we would rather ship two countries we have verified than five we have not.
United States
Select any compound to open the regulator's own record behind it.
An approval does not cross the border with you.
Each regulator decides on its own. Bremelanotide is the clearest case here: an approved medicine in the United States, and no listing at all in Canada's drug database. European rows appear only where we have checked the EMA record.
| Compound | United States | Canada | European Union |
|---|---|---|---|
| Semaglutide | Approved | Approved | Approved |
| Tirzepatide | Approved | Approved | Approved |
| Tesamorelin | Approved | Approved | not checked |
| PT-141 (bremelanotide) | Approved | Not approved | not checked |
| Retatrutide | Not approved | Not approved | not checked |
| BPC-157 | Not approved | Not approved | not checked |
| TB-500 | Not approved | Not approved | not checked |
| Ipamorelin / CJC-1295 | Not approved | Not approved | not checked |
| MOTS-c | Not approved | Not approved | not checked |
| GHK-Cu | Not approved | Not approved | not checked |
Does the answer change from state to state?
Not for approval. Whether a peptide is an approved medicine is decided federally, so that answer is the same in all fifty states. What does change between states is who may prescribe or compound it and under what supervision, which is a question about medical practice rather than about the compound. Pick a compound, then hover any state to see the answer that applies there.
An approved prescription medicine. Compounded copies are a separate question, and that rulemaking is live. Approval is federal, so this is identical in every state. Only prescribing and compounding oversight differ, and those sit with each state's own boards.
What regulators published about peptides.
Rules, proposed rules and notices, straight from the federal record and fetched when this page loads. Open a compound above to narrow it. This is the primary material, not somebody's summary of it, and it is where a change in status shows up first.
Questions people actually ask.
Some are and most are not. Four of the ten compounds on this page are approved prescription medicines, including semaglutide and tirzepatide. The other six have no approved human medicine at all, which means there is no legal route to obtain them for human use, whatever a seller's label says.
This is information, not legal advice.
We are not your lawyers and we do not know your situation. Regulatory status moves, sometimes in a single notice, and a page checked on 2026-07-30 can be out of date by the time you read it. Every status here names the regulator it came from so you can check it at the source, which is the only answer that counts. For anything with a consequence, ask a qualified lawyer or a clinician in your own country.
