Complete Melanotan II protocol for skin tanning, libido enhancement, and appetite suppression. Loading and maintenance dosing, mole monitoring, and safety.
This protocol references data from the PeptideWiki research database.
Melanotan II (MT-II) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH). It was originally developed at the University of Arizona in the 1990s by Dr. Victor Hruby and Dr. Mac Hadley as a sunless tanning agent to reduce skin cancer risk. The peptide activates melanocortin receptors throughout the body, producing three distinct pharmacological effects: skin darkening (MC1R), sexual arousal (MC3R/MC4R), and appetite suppression (MC4R).
When to use Melanotan II: You want tanning as the primary goal and are comfortable with the secondary sexual arousal and appetite effects. You accept the mole monitoring requirements.
When to use Melanotan I: You want tanning with a cleaner side effect profile and are willing to source a less commonly available peptide. Afamelanotide (Scenesse) has been through clinical trials and is FDA-approved for erythropoietic protoporphyria (EPP).
