GHRP-2 at a glance
GHRP-2 is a synthetic growth hormone-releasing peptide (hexapeptide) that stimulates pituitary GH release through the ghrelin receptor. Used in research settings and by compounding pharmacies. Mechanism: GHRP / GH secretagogue. Typical route: Subcutaneous. FDA status: Not FDA-approved. Used in clinical research and dispensed by compounding pharmacies.
Drug classGHRP / GH secretagogue
Half-life~30 minutes
RouteSubcutaneous
Common dosing100-300 mcg, 2-3x/day
FDA statusNot approved
Available throughCompounding pharmacies
Mechanism of action
GHRP-2 binds the growth hormone secretagogue receptor (GHS-R1a, the ghrelin receptor) on pituitary somatotrophs, stimulating endogenous growth hormone release. Effects are most pronounced when combined with a growth hormone-releasing hormone (GHRH) analog such as CJC-1295.
Dosing reference
Subcutaneous: 100-300 mcg, two to three times daily, often combined with CJC-1295 1295 100 mcg per dose. Standard protocols dose on an empty stomach and around exercise or before bed.

Frequently asked questions about GHRP-2
How does GHRP-2 compare to GHRP-6?
GHRP-2 stimulates less appetite (less ghrelin-like effect) and is generally preferred when patients want GH stimulation without the increased hunger that GHRP-6 commonly causes.
Is GHRP-2 worth using with CJC-1295?
The combination (GHRP + GHRH analog) produces a larger and more sustained GH pulse than either alone. CJC-1295/Ipamorelin is a more commonly prescribed pairing today.
