Growth Hormone Peptides: Common Questions

What is CJC-1295 (Mod GRF 1-29)?

CJC-1295 without DAC is a 29-amino-acid GHRH analog with four substitutions that extend its half-life to ~30 minutes. It produces a sharp, physiologically-timed GH pulse. It was never FDA-approved and remains a research compound.

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

With DAC, the half-life extends to 1-2 weeks, allowing weekly dosing. Without DAC (Mod GRF), the half-life is ~30 minutes, producing acute pulses closer to natural rhythm. Different research applications, different exposure profiles.

Is sermorelin the same as CJC-1295?

No. Sermorelin is the unmodified 29-amino-acid GHRH(1-29) with prior FDA approval (Geref, withdrawn 2008 for commercial reasons). CJC-1295 without DAC carries four amino acid substitutions for stability. Sermorelin retains compounding eligibility; CJC-1295 does not.

Are GH peptides FDA approved?

Only sermorelin (prior approval, discontinued) and tesamorelin (Egrifta, approved for HIV lipodystrophy) have FDA history. All other GH secretagogues — CJC-1295, GHRP-2/6, Ipamorelin — are research compounds without approval.

What purity should GH research peptides have?

≥99% HPLC purity with third-party batch documentation is the research standard. We publish COA results for every production run.
