What it is

CJC-1295 with Ipamorelin is the most widely compounded growth-hormone-axis blend. It pairs a GHRH analog (CJC-1295) with a growth-hormone secretagogue / GHRP (Ipamorelin).
Key point: This combination pairs a GHRH analog with a GHRP to target two different mechanisms of growth hormone release, which is studied for a larger, cleaner pulse than either alone.
Why these are combined
How the Combination Works
The two act on different arms of GH release. CJC-1295 supports a sustained GHRH signal, while Ipamorelin triggers a discrete GH pulse and is noted in research for being relatively selective (less effect on cortisol or prolactin than older GHRPs).
A GHRH analog plus a GHRP is studied for a larger, cleaner pulse than either alone, which is why this specific pairing dominates the compounding world.
The components
- CJC-1295 — a GHRH analog studied for sustained growth-hormone-releasing signaling.
- Ipamorelin — a selective GHRP / secretagogue studied for a clean GH pulse.
Reconstitution and blending

Both are lyophilized and reconstituted with bacteriostatic water; they are commonly co-drawn. The DAC and no-DAC (Mod GRF 1-29) forms of CJC-1295 differ in half-life, which changes how a blend is timed.
Our reconstitution and DIY blend calculators handle the per-cartridge volumes and beyond-use timing once you have decided what shares a cartridge.
Status in sport
Both components are prohibited in sport under WADA S2 (peptide hormones, growth factors, releasing factors and secretagogues), prohibited at all times.
