What CJC-1295 is
CJC-1295 refers to a stabilised version of the first 29 amino acids of GHRH, the portion that carries its biological activity. Variants with and without a 'drug affinity complex' (DAC) differ greatly in half-life, so always check which one a supplier means.
It acts on the GHRH receptor in the pituitary, the opposite arm of GH regulation from ghrelin-receptor agonists.
What the research literature studies
- GHRH-receptor binding and cAMP signalling
- Effect of DAC modification on peptide stability
- Combined GHRH and secretagogue signalling in vitro
Evidence rating: 2/5
Mostly animal and in vitro. A few small early human studies. Never approved. See our methodology for how levels are assigned.
- 'CJC-1295' is used loosely: the DAC and no-DAC forms are different molecules.
Regulatory status
CJC-1295 is not an approved medicine with the MHRA, EMA or FDA. Nordapep supplies it for in vitro laboratory research only.

CJC-1295 FAQ
What is the difference between CJC-1295 with and without DAC?
DAC adds a chemical group that binds albumin and greatly extends half-life. The no-DAC form (Mod GRF 1-29) is much shorter-acting.
Where can I buy CJC-1295 for research?
Nordapep does not currently list CJC-1295. You can ask Nordapep about availability, or compare related compounds that are in stock.
Is CJC-1295 approved?
CJC-1295 is not an approved medicine with the MHRA, EMA or FDA. Nordapep supplies it for in vitro laboratory research only.
