02Mechanism of Action
CJC-1295 (without DAC) is a modified analog of growth-hormone-releasing hormone (GHRH) fragment 1-29. It acts as a GHRH-receptor agonist on pituitary somatotrophs, studied for its capacity to stimulate growth-hormone release while preserving the natural pulsatile pattern.
The amino-acid substitutions improve enzymatic stability relative to native GRF. Research is confined to endocrine-signaling and pituitary-secretion models.

05FAQ
What is CJC-1295?
CJC-1295 is a growth-hormone-releasing hormone (GHRH) analog studied for its effect on pulsatile growth-hormone release via the GHRH receptor in research models. It is a research-use-only compound.
What does 'no DAC' mean for CJC-1295?
'No DAC' refers to the version without the Drug Affinity Complex modification; it is also called Modified GRF 1-29 and has a shorter half-life than the DAC variant in research contexts.
What is CJC-1295's molecular weight?
CJC-1295 (no DAC) has an approximate molecular weight of 3,367.8 g/mol and CAS number 863288-34-0.
How should CJC-1295 be stored?
CJC-1295 ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is CJC-1295 approved for human use?
No. CJC-1295 is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is CJC-1295 tested at Ethos Bio?
Every CJC-1295 lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
