Melanotan II

A melanocortin-agonist peptide studied in pigmentation and melanocortin research.

Half-life
~1 hour
Routes
subcutaneous

Overview

Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone studied in research literature for its interactions with melanocortin receptors, including pathways related to pigmentation. It is a commonly referenced compound in melanocortin-system research contexts.

Referenced research ranges

250500 mcg, once daily — research protocols reference a lower initial amount with gradual adjustment

Reconstitution default

10 mg in 5 mL yields 2 mg/mL; a 250 mcg reference dose is 0.125 mL (12.5 units on a U-100 syringe).

Storage

Store lyophilized vials in a cool, dark place; refrigerate after reconstitution and protect from light.

Considerations

  • Acts broadly across melanocortin receptor subtypes in research models.
  • Literature commonly references a low starting amount with gradual adjustment.
  • Reconstituted peptide is temperature-sensitive and light-sensitive.
