What this means

  • 01

    No product containing Ghrelin is approved by FDA for any use in the United States, so nothing on the market is authorized for people.

  • 02

    "Research use only" is a vendor label, not a legal category that permits human use. It does not exempt a product from medicines law.

  • 03

    Importing, supplying or promoting it for human use can fall under medicines legislation in the United States. This page is general information, not legal advice.

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.
