Is CJC-1295 safe?

Limited Evidence

Side effects, risks, and safety considerations based on available research.

Research status

CJC-1295 has very limited human safety data. Most information comes from animal studies, in vitro research, or anecdotal reports. This means the true risk profile in humans is largely unknown.

Known concerns & side effects

  • ⚠not FDA approved for any indication
  • ⚠long-term safety data in humans is very limited
  • ⚠US compounding legality has changed repeatedly: it was previously on the FDA's restricted "Category 2" list, and is not on that list as of the FDA's April 22, 2026 update (sources differ on exactly when it came off). It is not FDA-approved and not on the 503A bulks list — don't assume the current status is permanent
  • ⚠may cause water retention, tingling, and flushing
  • ⚠potential risk of stimulating growth of existing tumors via IGF-1 elevation
  • ⚠injection-based — carries infection risk without medical supervision

Frequently asked questions

What is the CJC/Ipamorelin stack?

CJC-1295 and Ipamorelin are commonly combined because they stimulate growth hormone release through different mechanisms (GHRH and ghrelin pathways respectively). The combination is thought to produce a stronger, more natural GH pulse than either alone. This stack is popular in anti-aging clinics but is not FDA approved.

What is the difference between CJC-1295 with and without DAC?

DAC (Drug Affinity Complex) extends the half-life of CJC-1295 from about 30 minutes to several days. CJC-1295 with DAC produces a sustained GH elevation, while Modified GRF 1-29 (without DAC) produces shorter, more physiological GH pulses. Many practitioners prefer the non-DAC version for more natural pulsatile release.

Is CJC-1295 legal to buy?

Its status has been unstable. CJC-1295 was previously on the FDA's restricted "Category 2" list and is not on that list as of the FDA's April 22, 2026 update. That does not mean it is FDA-approved as a drug or on the 503A bulks list — it remains an unapproved substance sold through the research/compounding market, and the legal picture could change again.
