| Evidence Tier | Research Compound |
|---|---|
| Category | Muscle Growth & Performance |
| Class | Synthetic hexapeptide GH secretagogue (GHRP); first-generation ghrelin mimetic |
| Molecular Target | GHS-R1a (ghrelin receptor) agonist; stimulates pituitary GH release and endogenous ghrelin; strong appetite/hunger signal |
| Sequence | His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 |
| Molecular Weight | ~873 Da |
| CAS | 87616-84-0 |
| Parent | Ghrelin mimetic |
| Mechanism | It is a strong activator of the ghrelin receptor. While it causes a pulse of growth hormone, it also sends an overpowering signal to the stomach and brain to increase appetite immediately. |
| Studied For | GH release stimulation, Appetite stimulation / hunger research, GI motility research, GH secretagogue research, IGF-1 elevation, Muscle growth via GH axis, Fat loss via GH, Body composition research, Ghrelin axis signaling, Pituitary GH function testing, Anti-aging via GH, Gastric motility and emptying, Cytoprotective GI effects, GH pulse amplitude research, Lean mass increase, appetite stimulation, growth hormone secretagogue, gastric motility, muscle growth, recovery |
