| Evidence Tier | Investigational |
|---|---|
| Category | Muscle Growth & Performance |
| Class | Synthetic hexapeptide GH secretagogue (GHRP); ghrelin mimetic |
| Molecular Target | GHS-R1a (ghrelin receptor) agonist on pituitary somatotrophs and hypothalamus; stimulates GH and ghrelin |
| Sequence | D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2 |
| Molecular Weight | ~818 Da |
| CAS | 158861-67-7 |
| Parent | Ghrelin mimetic |
| Mechanism | It mimics the hunger hormone (ghrelin) and binds directly to a receptor in the brain, forcing a rapid and intense release of growth hormone into the bloodstream. |
| Studied For | GH deficiency diagnosis, GH secretagogue research, Growth hormone stimulation, IGF-1 elevation, Pituitary function testing, Anti-aging via GH axis, Body composition / lean mass, Fat loss research, Appetite stimulation, Muscle growth and repair, Bone density via GH, Recovery acceleration, Ghrelin axis research, GH pulse amplitude, Adult GH deficiency models, Metabolic rate improvement, Sleep quality via GH, Cardiac function research, growth hormone secretagogue, appetite stimulation, muscle growth, recovery, anti-aging |
