Ipamorelin
Also known as: Growth hormone secretagogue · GHRP
A selective growth-hormone secretagogue (a pentapeptide) studied for pulsatile GH release with minimal effect on other hormones.
Ipamorelin is a synthetic pentapeptide classified as a growth hormone secretagogue (GHS) — it acts on the ghrelin/GH-secretagogue receptor to stimulate the pituitary to release its own growth hormone in a pulsatile, physiological pattern.
It is studied for its selectivity: relative to older secretagogues it is reported to prompt GH release with comparatively little impact on cortisol or prolactin. In research protocols it is frequently combined with a GHRH analog such as CJC-1295, because the two act on complementary pathways.
Supplied lyophilised for research use only; reconstitute with bacteriostatic water. HPLC-verified with a Certificate of Analysis.

GHRH
Growth-Hormone-Releasing Hormone — the hypothalamic hormone that signals the pituitary to release growth hormone.
GHRP
Growth Hormone Releasing Peptide — a class acting on the ghrelin receptor to trigger pulsatile GH release.
Half-Life
The time for a compound’s concentration to fall by half — a key determinant of dosing frequency in research.
Subcutaneous
Into the layer of fat just beneath the skin — the route most peptide research protocols reference.
Reconstitution
The process of dissolving a lyophilised (freeze-dried) peptide in a sterile solvent such as bacteriostatic water before study.
