Research background

About GHRP-2

GHRP-2 is one of the growth-hormone-releasing peptides, small synthetic peptides that act at the ghrelin receptor (GHSR). It has six residues, several of them D-amino acids or non-natural, and an amidated C-terminus. Under the name pralmorelin it was developed in Japan as a diagnostic agent for GH secretion.

Published human pharmacology includes a phase I study of its pharmacokinetics (Pihoker et al., 1998) and a study showing that, like ghrelin, it increases food intake (Laferrère et al., 2005); animal work has looked at pain processing (Zeng et al., 2014). It sits in Hormone & growth axis with GHRP-6, Ipamorelin and Hexarelin.

GHRP-2 FAQ

How does GHRP-2 differ from Ipamorelin?

Both act at the ghrelin receptor. Ipamorelin is the more selective of the two, with little effect on cortisol or prolactin, while GHRP-2 and GHRP-6 are less selective. Which one fits depends on what your experiment needs to isolate.

Why is GHRP-2 also called pralmorelin?

Pralmorelin is its non-proprietary drug name from its development as a diagnostic agent; GHRP-2 is the research name. Both refer to the same hexapeptide, CAS 158861-67-7.

How to order

Ordering GHRP-2 from Medabol

Kit and minimum: GHRP-2 is sold by the kit: 10 vials of one specification (5 mg, 10 mg and 15 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price: Reference prices are listed per kit above, from $50.60. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so GHRP-2 adds up with anything else you order; your written quote has the final price.
Documents: Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping: Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment: Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal: Listed under Hormone & growth axis — GH secretagogues, GHRH analogues, IGF-1 variants and reproductive-axis peptides.
