Mechanism of Action

Selective ghrelin receptor agonist (GHSR-1a). Stimulates pituitary GH secretion with high specificity, without significant activation of cortisol, acetylcholine, or prolactin pathways.

Published Research Ranges & Study Context

Studies have administered: 100–300mcg per administration, 1–3x daily in research literature

Important Research Framing These are ranges reported in published scientific studies. They are provided for educational context only and do not constitute dosing recommendations. Individual study parameters vary by design, population, and research objectives. This information is not medical advice.
Primary Research Findings

Animal and early human studies show significant GH pulse amplitude increase with favorable safety profile. Selectivity for GH without cortisol elevation distinguishes it from other GHRPs.

Moderate Evidence Phase 1/2 human trials available
Side Effects Observed in Research

Mild water retention, transient growth hormone flush; generally considered cleanest GHRP in research
