About Melanotan I – 10MG

Melanotan I, also known as afamelanotide, is a synthetic linear analog of alpha-melanocyte-stimulating hormone (alpha-MSH). It is a tridecapeptide (13 residues) built on the [Nle4, D-Phe7]-alpha-MSH modification, first synthesized in the search for a more potent and stable melanocortin agonist. It is catalogued under CAS 75921-69-6 and PubChem CID 16197727, and functions as a non-selective melanocortin-receptor agonist with particular activity at MC1R, the receptor governing melanin synthesis.

Supplied as a 10mg lyophilized vial, Helio's Melanotan I is intended strictly for in vitro and preclinical Research Use Only and is not for human or veterinary use. Research applications center on melanocortin-receptor pharmacology and pigmentation-pathway biology.

Research use only — not for human or animal consumption. Per-batch documentation is provided with the material.

Handling and Storage Tips:

Keep peptides cold and away from light once received.

For short-term use (days to weeks), refrigeration at 4°C (39°F) is acceptable.

Lyophilized peptides are typically stable at room temperature for several weeks, making it suitable for moderate-term storage.

For long-term storage (months to years), it’s best to freeze peptides at -80°C (-112°F). Freezing optimally preserves peptide stability for extended periods.

Research Context
Melanocortin pharmacologyStudied as a non-selective melanocortin-receptor agonist in receptor-binding assays.
Pigmentation biologyInvestigated in melanocyte models for melanin-synthesis pathway activation via MC1R.
Photoprotection researchExamined preclinically in models relevant to UV-induced skin damage.
Structure-activity studiesReference [Nle4, D-Phe7]-alpha-MSH analog for melanocortin SAR work.
Peptide-stability researchStudied for enhanced metabolic stability relative to native alpha-MSH.
Research Findings

Melanotan I (afamelanotide) arose from work identifying [Nle4, D-Phe7]-alpha-MSH as an analog roughly a thousand-fold more potent than native alpha-MSH, owing to substitutions that improve receptor affinity and metabolic stability. It shares the conserved His-Phe-Arg-Trp melanocortin active-site motif and acts primarily through MC1R to drive melanin synthesis in preclinical melanocyte models.

The compound is well characterized in the melanocortin literature and has an established regulatory history as a clinical agent for erythropoietic protoporphyria; however, material offered here is for laboratory research only, with no human efficacy or dosing claims made.

History

Melanotan was developed in the 1980s by Victor Hruby and colleagues at the University of Arizona, who identified [Nle4, D-Phe7]-alpha-MSH as a highly potent, stable melanocortin agonist later designated Melanotan I and subsequently developed as afamelanotide.
