GHRP-2: Research Profile, Dosages & Supplier Prices
GHRP-2 is a growth hormone secretagogue compound with a molecular weight of 818.0 g/mol and a research half-life of approximately 15-60 minutes in published research. GHRP-2 (pralmorelin) is a hexapeptide growth hormone secretagogue and ghrelin receptor agonist, one of the original growth hormone releasing peptides. It has human clinical research history in Japan (as KP-102) for GH deficiency diagnostics.

What is GHRP-2?
Compared to ipamorelin, GHRP-2 is less selective - published studies note modest cortisol and prolactin elevation alongside GH release. It remains widely researched for GH axis pharmacology and is among the cheapest secretagogues to synthesize.
As a simple hexapeptide, GHRP-2 should be inexpensive. Quality issues are rare but underdosing occurs at the bottom of the market.
Mechanism of Action (Research Context)
Ghrelin receptor (GHS-R1a) agonist stimulating GH release, with secondary effects on ACTH/cortisol and prolactin documented in published studies.
