GHRP-2 - Dragon Pharma

Buy GHRP-2 5 mg by Dragon Pharma at XSteroids. GHRP-2, also called pralmorelin, is the first ghrelin-type growth hormone secretagogue to reach clinical practice - and the only one in this group that is an approved diagnostic product anywhere. Dragon Pharma supplies it as a 5 mg lyophilized vial. This guide covers the pharmacology, ghrp-2 dosage practice, the appetite effect and how it differs from other secretagogues.

GHRP-2 is a prescription diagnostic in Japan and is not approved for general therapeutic use, so the information below is educational only.

About GHRP-2 by Dragon Pharma

Pralmorelin, best known as growth hormone-releasing peptide 2 or GHRP-2, is a synthetic peptide and specifically an analogue of met-enkephalin, with the sequence D-Ala-D-(beta-naphthyl)-Ala-Trp-D-Phe-Lys-NH2. It is orally active, and it works as an agonist of the ghrelin / growth hormone secretagogue receptor (GHSR).

Its clinical role is narrow but real: Kaken Pharmaceutical markets it in Japan as a single-dose preparation for assessing growth hormone deficiency. It was the first drug of this class to enter clinical use, which is why it appears in pituitary function testing panels alongside agents such as Sermorelin.

How GHRP-2 Works

Mechanism of Action

By activating the ghrelin receptor in the pituitary and hypothalamus, GHRP-2 triggers growth hormone release through a pathway distinct from the GHRH receptor. Acute administration markedly increases plasma GH in humans, and that reliability is exactly what makes it useful as a diagnostic challenge.

The Appetite Effect

GHRP-2 also reliably induces hunger and increases food intake in humans - a documented effect, not an anecdotal one. That is a meaningful difference from Ipamorelin, which is prized for its selectivity and lack of comparable hunger signalling.

GHRP-2 Dosage and Protocols

Dosing

As a short-acting secretagogue, GHRP-2 is dosed close to the injection window that matters: research protocols inject in small amounts, and practice typically centres on one or two administrations a day, with the pre-sleep dose timed to natural GH release. The 5 mg vial is a standard research size, and the reconstitution ratio decides how many units on an insulin syringe equal a given amount.

Reconstitution

Mix the lyophilized powder with bacteriostatic water, aiming the stream at the vial wall rather than the powder, then swirl gently instead of shaking. Label the vial with the date, keep it refrigerated, and treat a punctured multi-dose vial as usable for 28 days after the first puncture.

GHRP-2 vs Ipamorelin and GHRP-6

The three ghrelin-type secretagogues in this catalog differ mainly in selectivity. Ipamorelin does not stimulate ACTH or cortisol, which makes it the cleanest of the group. GHRP-2 and GHRP-6 do affect the corticotropic axis, and both are known for appetite stimulation. GHRP-2 is the one with a regulatory footprint, since it is an approved diagnostic in Japan; it is also often paired with a GHRH analogue such as CJC-1295 for the two-pathway approach, just as Hexarelin is used in research logs.

GHRP-2 Side Effects and Regulatory Status

The documented effects beyond GH release are hunger and increased food intake, plus the corticotropic stimulation that distinguishes it from ipamorelin. Development for growth hormone deficiency and short stature reached phase II but never resulted in a marketed treatment - possibly because people with GHD respond less to it, which limits its therapeutic value. In sport, GH secretagogues are restricted under anti-doping rules, and the peptide sold for research use has no approved therapeutic indication outside the Japanese diagnostic setting.

Storage Instructions

Store the lyophilized vial in a cool, dry place away from direct light before reconstitution. After mixing with bacteriostatic water, keep the solution refrigerated and use it within the recommended period for peptide solutions. Keep vials out of the reach of children.
