About Melanotan I

Melanotan I (afamelanotide / NDP-MSH) is a linear analog of α-melanocyte-stimulating hormone studied for MC1R-driven melanogenesis and photoprotection research. It is a more receptor-selective reference melanocortin than Melanotan II. TagPep is adding Melanotan I as a research-use-only reference material.

Mechanism studied in research

Selective agonism at MC1R studied for eumelanin synthesis and UV-response pathways in melanocyte research models.

Areas of research investigation

  • MC1R-signaling assays
  • Melanogenesis research
  • Photoprotection model systems
  • Comparative melanocortin selectivity

Laboratory handling

Lyophilized; research reconstitution with bacteriostatic or sterile water, refrigerated solution, frozen light-protected powder.

Melanotan I research FAQ

Is Melanotan I more selective than Melanotan II?

Yes — Melanotan I (NDP-MSH) is studied as a more MC1R-selective analog, while Melanotan II acts across multiple melanocortin receptors.

What is afamelanotide?

Afamelanotide is another name for Melanotan I. TagPep references it as research-use-only material.

Research use only. Melanotan I is supplied as a laboratory reference material for in-vitro and research applications. It is not a drug, supplement or medical product, and is not intended for human or veterinary use, consumption, or clinical application.
