Sermorelin
Also known as: GHRH(1-29) · GRF 1-29
A GHRH(1-29) fragment — the shortest sequence of GHRH that retains activity — studied for endogenous growth-hormone release.
Sermorelin is a truncated analog of GHRH consisting of its first 29 amino acids (GHRH 1-29), the shortest fragment that still fully activates the GHRH receptor. It stimulates the pituitary to release the body’s own growth hormone.
It is one of the longest-studied GHRH analogs and often serves as a reference secretagogue in research. Like Tesamorelin and CJC-1295 it belongs to the GHRH-analog branch of the GH axis, distinct from the ghrelin-receptor GHRPs.

A substance that prompts a gland to secrete a hormone — e.g. a GH secretagogue triggers the pituitary to release growth hormone.
Tesamorelin
A stabilised GHRH analog studied for stimulating endogenous growth-hormone release, notably in visceral-fat research.
CJC-1295
A synthetic GHRH analog studied for stimulating sustained, endogenous growth-hormone release, often paired with a GHRP.
Ipamorelin
A selective growth-hormone secretagogue (a pentapeptide) studied for pulsatile GH release with minimal effect on other hormones.
Pituitary Gland
The "master gland" at the base of the brain that releases growth hormone and other hormones on hypothalamic command.
