CJC-1295 Side Effects: Safety Signals and Warnings
CJC-1295 safety concerns are compound-specific. The main listed side effects are Flushing and warmth after injection, Headache, and Water retention. The main warning signals are Not FDA-approved, One death reported in a clinical trial (cause disputed), and DAC version may disrupt natural GH pulsatility.
Direct Answer
CJC-1295 has Phase 1/2 human data demonstrating sustained GH and IGF-1 elevation, but no Phase 3 trials or approved indication exist. Evidence is materially stronger than most GH secretagogues in the library but weaker than tesamorelin (FDA-approved). For GHRH-analog research, tesamorelin is the higher-confidence starting point; CJC-1295 is a reasonable secondary candidate.
