GHRP-2

A hexapeptide ghrelin receptor (GHS-R1a) agonist; stimulates GH release by increasing GHRH release and reducing somatostatin tone.

Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.

Studied for GH secretion, appetite/energy balance, and neuroendocrine research; also used as a clinical diagnostic agent for GH deficiency.

• Growth hormone supportStudied for how it interacts with the body's own growth-hormone axis in research settings.

Limited human data in the US; approved in Japan since 2004 as the diagnostic agent pralmorelin (GHRP Kaken) for GH deficiency, but not FDA-approved.

Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.

• Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
• Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
• Vendor reputation. See how the vendor is talked about in the community before trusting a new name.

Research context only — VialGrade never gives dosing, medical, or human-use guidance.
