MELANOTAN I10 mg RUO

Melanotan I

A real tan with built-in UV protection, from selective MC1R activation.

  • A real tan without the sun, stimulates the body's own melanin through MC1R
  • The gentler tanning peptide: far less nausea than MT-2, minimal off-target effects
  • Its analog afamelanotide is FDA-approved (Scenesse), the only approved alpha-MSH analog

Why researchers choose it

Melanotan I tells the skin to make more of its own melanin, and the sun protection that comes with it, while barely touching the other melanocortin receptors. That selectivity is the point: next to MT-2 it's reported to be cleaner, with less nausea and smaller libido and appetite effects. Its close relative afamelanotide is the only tanning-type peptide to reach FDA approval.

Reconstitution reference concentration only, not dosing

Set the vial strength and how much bacteriostatic water you draw into it. This returns the resulting concentration for lab handling. It is a dilution reference, not a dosing recommendation.

Most compounds reconstitute with bacteriostatic water; a few acid-loving peptides use acetic acid instead. How much to draw, and how many vials a cycle needs, live in the Complete Peptide Guide, not here.

How much, and how many vials for a full cycle?

Protocol and cycle-length questions get answered in the Complete Peptide Guide, not here. These listings carry no dosing.
