Melanotan-1 is Certified Aminos' research listing for [Nle4, D-Phe7]-α-MSH, the same peptide sequence developed pharmaceutically as afamelanotide (Scenesse). It is selective for the MC1 receptor, distinct from Melanotan-2's broader MC1/MC3/MC4 receptor activity. Available in 10mg for laboratory research use only.

Each order ships as a Melanotan-1 research peptide in a 10mg vial, manufactured for laboratory use only.
| Product Name | Melanotan-1 |
|---|---|
| Molecular Identity | [Nle4, D-Phe7]-α-MSH -- same sequence as afamelanotide (Scenesse) |
| Sequence | Ac-Ser-Tyr-Ser-Nle-Glu-His-D-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2 -- independently confirmed via ChEMBL |
| Molecular Formula / MW | C78H111N21O19, ~1646.9 g/mol -- independently confirmed via ChEMBL |
| CAS Number | 75921-69-6 -- a commonly published literature value |
| Primary Receptor Target | MC1R-selective, distinct from Melanotan-2's broader MC1/MC3/MC4 profile |
| Related Regulatory Note | This sequence is marketed pharmaceutically as afamelanotide (Scenesse), FDA-approved October 8, 2019, and EU-approved December 2014, for erythropoietic protoporphyria. That approval and safety data apply to the Scenesse implant formulation, not to this RUO research listing |
| Purity | Not independently verified -- no batch-specific COA is currently published |
| Identity | Not independently confirmed by mass spectrometry or an equivalent method |
| Available Size | 10mg |
| Intended Use | Laboratory research only (RUO) |
When your order arrives, match the lot number printed on the vial to the lot number on the COA before beginning any work. Until a batch-specific COA is published for this product, treat any purity or identity figure shown elsewhere on this listing as a supplier claim, not an independently verified result.

Melanotan II non-selectively activates three melanocortin receptors — here's what controlled trials and case reports actually show, not what badges imply.

Melanotan-1 shares its exact sequence with the FDA-approved drug Scenesse — here's what that does and doesn't mean for a research-use listing, and what MC1R research actually shows.

HCG and LH bind the exact same receptor — yet research shows they send measurably different signals once they do. Here's what's actually established about HCG's structure, mechanism, and the FDA's position on HCG weight-loss claims.
