What Alpha-MSH is
The natural melanocortin hormone behind skin pigmentation, appetite, and inflammation, and the template for melanotan and related peptides.
Alpha-MSH is the natural melanocortin peptide that stimulates pigment production, influences appetite through central melanocortin receptors, and has anti-inflammatory activity. It is the biological template for the melanotan peptides and for the anti-inflammatory fragment KPV.
Mechanism: Agonizes melanocortin receptors to drive pigmentation (MC1R), appetite and energy balance (MC4R), and anti-inflammatory effects.
Regulatory history: Native hormone; melanocortin-based drugs are approved for specific uses
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 Alpha-MSH 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.
