Not medical advice. GHRP-2 is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.
GHRP-2 is listed in our catalogue under “HGH / Somatropin.” In scientific publications it is discussed in technical language; this page translates the general themes into everyday wording while staying faithful to research-only framing.
One-paragraph overview from our research datasheet — still scientific, but faster to read than the full mechanism list below.
GHRP-2 (Pralmorelin), potent hexapeptide GHS-R1a agonist and first clinically approved growth hormone secretagogue for GHD diagnostic applications.
Peer-reviewed literature typically discusses GHRP-2 in specific experimental settings. The points below reflect how the scientific community frames this compound—not as health claims, but as the research questions being asked.
Research vs. personal use: Literature describes experiments in controlled lab and animal models. This is distinct from any real-world use; our products are for laboratory research only.
Growth-hormone axis peptides are researched for how they signal through the GH/IGF pathway in animals and cells. Studies focus on endocrine biology and metabolism, not on prescribing or outcomes in people.
Our datasheet lists mechanistic themes observed in preclinical work. These are research endpoints, not health claims. They help scientists understand and compare pathways.
Storage requirements: Lyophilised powder: store in freezer (−20 °C). Reconstituted: refrigerate 1–6 °C, away from sunlight. Use within the validated stability window for the specific batch and formulation. · Learn best practices in our detailed storage guide.
Research dosing context: Literature typically discusses 100–300 mcg subcutaneously · 2–3 times daily · Functional t½ ≈ 15–30 min; peak GH at ~15 min post-administration; GH elevation persists ~60 min; oral bioavailability demonstrated but low (~0.3%); approved diagnostic dose: 100 mcg IV (GHRP Kaken 100). Rapid degradation in vivo, multiple daily administrations required for sustained effects.
Preparation steps: Follow our detailed reconstitution guide, use the calculator tool for volume confirmation, and always verify purity with the COA reading guide.
GHRP-2 is a stronger GH releaser per dose, but it also produces modest cortisol, ACTH, and prolactin elevation that ipamorelin does not. Ipamorelin is cleaner; GHRP-2 is more potent and has a richer clinical pharmacokinetic dataset. The choice depends on whether your research protocol needs selectivity or potency.
Moderate. GHRP-2 activates hypothalamic ghrelin receptors enough to produce a noticeable increase in hunger in research subjects, but less dramatically than GHRP-6, which is the strongest orexigenic member of the family.
Yes, oral bioactivity has been demonstrated across multiple species, though absolute oral bioavailability is quite low (roughly 0.3%). That means meaningful oral dosing requires much larger amounts than SC or IV, but the route does work in research protocols.
Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. GHRP-2 is reasonably stable in solution within the standard peptide-handling window.
