What it is

CJC-1295 is a synthetic analogue of growth hormone releasing hormone (GHRH). The “DAC” is a Drug Affinity Complex: a chemical modification that binds it to albumin in the blood so it lasts days rather than minutes. Its human research so far consists of pharmacokinetic studies, with no outcome trials yet.{{CITE:teichman-2006}}{{CITE:ionescu-2006}}

It is almost always discussed and used paired with ipamorelin, and it is one of the most commonly dispensed compounds in anti-ageing clinics.

Two different products share this name, and the distinction is important enough that it appears twice in this book. See Mod GRF (1-29).
