Short answer
It depends on the peptide and how it is sold. Approved peptide drugs (insulin, semaglutide, tirzepatide, Vyleesi, Egrifta and others) are legal with a prescription. Many popular peptides — BPC-157, TB-500, CJC-1295, ipamorelin and others — are not approved drugs; in 2023 the FDA put many of them in "Category 2" (bulk substances that may present significant safety risks) of its interim compounding policy. In April 2026 several, including BPC-157, TB-500 and CJC-1295, were moved off Category 2 because the nominations were withdrawn — not because FDA found them safe — and none was added to the list of substances pharmacies may compound from; four peptides remain in Category 2: ipamorelin acetate, GHRP-2 and GHRP-6 for outsourcing facilities (503B), and kisspeptin-10 for 503A pharmacies. See the FDA compounding safety-risk page. Vials sold "for research use only, not for human consumption" are not legal to market as medicines for people. Many peptides are also banned in tested sport. This is general information, not legal advice; rules change and differ by country and state. Peptide Confessions does not publish dosing, timing, injection or sourcing guidance.
| Category | Examples | Status (US) |
|---|---|---|
| Approved peptide drugs | Semaglutide, tirzepatide, Vyleesi | Legal with a prescription |
| Compoundable peptides | Sermorelin (varies) | Prescription from a compounding pharmacy; rules in flux |
| Nominated research peptides | TB-500, BPC-157, CJC-1295 | Not approved; not on the list pharmacies may compound from (FDA page updated April 2026) |
| "Research use only" vials | Most online peptides | Not approved or legal to sell for human use |
Sport and other countries
WADA prohibits BPC-157, TB-500, growth-hormone secretagogues (CJC-1295, ipamorelin, GHRPs), AOD-9604 and many others, in and out of competition. In Canada, Health Canada has warned that unauthorized injectable peptides sold online are illegal to sell. See AOD-9604 and are peptides safe.
Buying, possessing and importing
US enforcement mostly targets sellers: FDA warning letters and import refusals go to companies marketing unapproved peptides for human use, often despite "research use only" labels. Buyers are rarely the focus, but personal orders from abroad can be detained or refused at the border, and repeated or large orders can draw attention. #171 describes ordering a few vials for a shoulder injury, then paying a lawyer after a customs stop turned into an investigation, without any charge. One story, not a typical outcome. This is general information, not legal advice; rules change and differ by country and state.
| Situation | Typical legal position (US) |
|---|---|
| Prescribed, approved peptide drug | Legal |
| Prescribed compounded copy of an approved drug | Restricted since FDA declared the tirzepatide and semaglutide shortages over |
| Selling unapproved peptides for human use | Illegal; FDA warning letters and seizures |
| Importing research peptides for personal use | Can be detained or refused at the border |
| Using a WADA-banned peptide as a tested athlete | Anti-doping violation, not a crime in itself |
Compounded GLP-1s after the shortages
Mass compounding of semaglutide and tirzepatide was allowed while they were on the FDA shortage list. The FDA declared the tirzepatide shortage resolved in December 2024 and the semaglutide shortage resolved in February 2025, after which pharmacies lost the shortage exemption for routinely copying those drugs. Some still compound personalised versions under patient-specific rules, which remains contested. See compounded semaglutide and compounded tirzepatide. Last reviewed October 15, 2026.
Outside the US
In Canada, selling unauthorized health products is illegal, and Health Canada has acted against online peptide sellers; see peptides in Canada. In the UK, prescription-only medicines and unlicensed injectables are regulated by the MHRA. In Australia, the TGA treats many research peptides as prescription-only, so importing them without a prescription can breach the rules. Laws change, so check the regulator in your country.

Community Q&A
- Can you get in trouble for buying peptides online?
- Enforcement mainly targets sellers, but imported packages can be detained, and in some cases buyers face investigation. It depends on the country and the circumstances.
- Is compounded semaglutide still legal?
- The shortage exemption ended after the FDA declared the semaglutide shortage resolved in February 2025. Patient-specific compounding continues under narrower rules and remains disputed.
- Are peptides legal in the US?
- Approved peptide drugs are legal with a prescription. Many popular research peptides are not approved, and none of the popular ones is on the list of bulk substances pharmacies may compound from. FDA status has shifted (see its compounding safety-risk page, updated April 2026).
- Is BPC-157 legal?
- BPC-157 is not an FDA-approved drug. FDA placed it in compounding Category 2 (possible significant safety risks) in 2023; in April 2026 it was moved off that category after its nomination was withdrawn, which is not a safety finding and does not make it compoundable. It is sold as 'research use only', which does not make it legal to sell for human use. It is banned by WADA.
- What does 'research use only' mean?
- The seller is saying the product is not for human consumption. It is not made or checked to medicine standards.
- Does Peptide Confessions say where to get peptides?
- No. We do not publish sourcing, vendor or price information.
