Growth Hormone Peptides
How GH secretagogues stimulate natural growth hormone release and what the research shows.
The Difference Between GH and GH Peptides
Exogenous growth hormone (synthetic HGH) directly introduces GH into circulation. GH peptides — called growth hormone secretagogues (GHS) — work differently. They stimulate the pituitary gland to produce and release its own GH. This distinction is important: the body's regulatory feedback mechanisms remain active, reducing the risk of the side effects associated with supraphysiological GH levels.
GHRH Analogues: CJC-1295
CJC-1295 is an analogue of growth hormone releasing hormone (GHRH). It binds the GHRH receptor on the pituitary and stimulates GH release. The DAC (Drug Affinity Complex) version extends its half-life from minutes to approximately 8 days by binding to serum albumin, creating sustained elevation of GH and IGF-1 levels.
Ghrelin Mimetics: Ipamorelin
Ipamorelin is a selective ghrelin receptor agonist. It stimulates GH release through a different receptor than GHRH, which means it can be stacked with CJC-1295 for additive effects. Its key advantage is selectivity — unlike older secretagogues like GHRP-6, Ipamorelin produces minimal elevation of cortisol or prolactin, making it a cleaner research compound.
The CJC-1295 + Ipamorelin Stack
This is one of the most studied and widely used GH peptide combinations in the research community. CJC-1295 provides a sustained GHRH signal while Ipamorelin provides a pulsatile ghrelin signal — together they amplify GH pulses more effectively than either alone. Research has shown meaningful increases in IGF-1 levels, which mediate many of GH's anabolic and restorative effects.
