What Ghrelin is
The body's own hunger hormone and the natural trigger for growth hormone release, and the template for the entire GHRP peptide class.
Ghrelin is a 28-amino-acid hormone made mainly in the stomach, discovered in 1999. It is the primary natural stimulator of growth hormone secretion and the only known circulating hormone that increases appetite.
Mechanism: Activates the GH secretagogue receptor (GHS-R1a) in the pituitary and hypothalamus, driving GH release and appetite.
Regulatory history: Endogenous hormone; not marketed as an approved drug
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Ghrelin at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
