What is CJC-1295 no DAC?
CJC-1295 without DAC — also referenced in the literature as modified GRF(1-29) — is a 30-amino-acid analog of growth-hormone-releasing hormone. It carries amino-acid substitutions that resist enzymatic degradation but omits the drug-affinity-complex (DAC) modification, so it does not bind serum albumin and clears quickly.
That short half-life is the point: it produces a sharp, pulse-like signalling profile rather than a sustained elevation. It is supplied as a lyophilized powder and reconstituted before use — see the reconstitution guide and the reconstitution calculator.
Research context
Research models use CJC-1295 no DAC to stimulate pituitary growth-hormone release in a pattern that more closely mimics endogenous pulsatility than long-acting analogs do, which matters in study designs where feedback regulation is part of what is being observed.
It is most often paired with a ghrelin-receptor secretagogue such as Ipamorelin to examine combined-pathway effects; the two are also stocked pre-combined as CJC-1295 / Ipamorelin. The stabilised GHRH analog Tesamorelin is the usual long-acting comparator.
Purity and third-party testing
Every batch is independently analysed by Testides and Peptide Test Canada and ships with a certificate of analysis reporting HPLC purity and MS identity. See how to read a certificate of analysis and what a purity figure actually means, or read about our process on the Research and Quality page.
Handling and storage
Kept cold and away from light in its lyophilized state; refrigerated and used within a shorter window once reconstituted. The storage guide covers both, and bacteriostatic vs. sterile water explains the diluent choice — bacteriostatic water is stocked alongside.
