FDA status, evidence and safety
Sold online, not approvedNot approved; marketed online
- FDA status
- Not FDA-approved. FDA listed CJC-1295 among substances that may pose significant safety risks in compounding (its “category 2”), then moved it to a list of substances whose nominations were withdrawn. That doesn't add it to the substances pharmacies may use. FDA safety-risk list ↗FDA compounding list ↗
- What's changing
- It isn't one of the six peptides in HHS's draft compounding policy of October 30, 2026, so nothing has changed for pharmacies. See what's changing →
- In people so far
- Healthy adults aged 21 to 61: after one injection, growth hormone rose 2 to 10 times for 6 days or more, and IGF-1 1.5 to 3 times for 9 to 11 days. PubMed ↗
- A phase 2 trial in people with HIV and excess belly fat was terminated. ClinicalTrials.gov ↗
- Safety
- The FDA says it has found serious side effects linked to CJC-1295, including a faster heart rate and a reaction in which blood vessels widen throughout the body. FDA safety-risk list ↗
- A 2026 review lists it among unapproved peptides marketed directly to patients, with scarce human safety data. PubMed ↗
- In sport
- Banned in sport at all times: WADA names CJC-1295 among growth-hormone-releasing factors (class S2). WADA ↗

Questions to ask your doctor
- Is CJC-1295 a sensible option for me, given my health and the medicines I take?
- Could CJC-1295 interact with any medicine or supplement I already take?
- What side effects should I watch for, and when should I stop or call you?
- How would we tell whether it is helping, and when should we review it?
This is general information gathered from the sources listed, not medical advice. Talk to your doctor before starting anything new.
