Modified GRF 1-29 · GHRH Analog
A long-acting GHRH analog for sustained growth hormone release
Typical Dose
1–2 mg per week
Route
Subcutaneous
Frequency
Once or twice per week
Cycle
8–12 weeks
CJC-1295 is a modified version of a hormone your brain naturally uses to tell your pituitary gland to release growth hormone. The original version of this signal lasts only minutes in your body. CJC-1295 was engineered to last days by attaching to a blood protein called albumin, which acts like a slow-release carrier. The result is a steady, sustained increase in growth hormone over time, rather than a quick spike. It is almost always used together with Ipamorelin for a synergistic effect.
CJC-1295 docks onto the GHRH receptor in your pituitary gland — the same receptor your brain's natural growth hormone signal uses. This tells the pituitary to produce and release growth hormone. What makes CJC-1295 different from the natural signal is its DAC modification, which lets it attach to albumin (a blood protein) and hitch a ride through your bloodstream for days instead of minutes. This keeps growth hormone levels elevated in a sustained, natural-feeling way rather than a sharp spike.
Typical Dose

CLINICAL NOTES
Almost always stacked with Ipamorelin for synergistic GH release. The combination provides a more natural, pulsatile GH release pattern.
IMPORTANT DISCLAIMER

CJC-1295 is almost always paired with a GHRP like Ipamorelin for synergistic GH release.
The gold-standard GH stack. CJC-1295 + Ipamorelin is the most researched and widely used GH optimization combination.
Hexarelin is a more potent GHRP — pairing with CJC-1295 produces strong GH pulses for muscle building.
GHRP-6 + CJC-1295 is a classic bulking stack due to GHRP-6's appetite-stimulating effects.
