GHRP-2 (pralmorelin) is a synthetic hexapeptide ghrelin-receptor (GHS-R1a) agonist that reliably triggers a large, short-lived pulse of endogenous growth hormone in humans. It is approved in Japan as a single-use diagnostic agent for growth hormone deficiency; no controlled trial has established that repeated administration produces durable changes in body composition, strength or health outcomes.
// our evidence grade — unedited
A real regulatory approval and validated diagnostic performance data in Japan lift GHRP-2 above the rest of the GHRP class, but nothing in the published record supports the body-composition and anti-ageing uses it is actually sold for, and it carries the same ACTH/cortisol, prolactin and appetite off-target burden as its parent compound.
We grade this compound and we sell it. The grade is set against our published criteria before any stocking decision and is not adjusted because it is in the catalogue.
