Melanotan II: Tanning & Sexual Function Research

Research on the melanocortin peptide with multiple physiological effects

Source: https://indexalabs.com/blog/melanotan-ii-tanning-sexual-function Abstract: Melanotan II is a synthetic melanocortin analog that produces both melanogenic (tanning) and sexual function effects. This guide covers its dual mechanisms and research applications.

1. Introduction

Melanotan II (MT-II) is a cyclic lactam analog of alpha-melanocyte stimulating hormone (α-MSH) developed at the University of Arizona. It activates melanocortin receptors producing both skin pigmentation and sexual arousal effects, leading to the development of PT-141 as a more selective sexual function peptide.

2. Mechanisms of Action

2.1 MC1 Receptor (Skin) Activation of MC1R on melanocytes stimulates eumelanin production, causing skin darkening.

2.2 MC3/MC4 Receptors (CNS) Central melanocortin activation produces sexual arousal and appetite suppression.

2.3 UV-Independent Tanning MT-II can induce pigmentation without UV exposure, though UV enhances the effect.

2.4 Appetite Effects MC4R activation may reduce appetite and food intake.

3. Research Applications

3.1 Photoprotection Research Studies on protective tanning for UV-sensitive individuals.

3.2 Sexual Function Research on libido and arousal mechanisms.

3.3 Obesity Research Studies on melanocortin-based appetite regulation.

3.4 Skin Disorders Research on conditions like erythropoietic protoporphyria.

4. Research Considerations

4.1 Available Sizes MT-II is available in 10mg vials.

4.2 Side Effects Common effects include nausea, flushing, and fatigue in research settings.

4.3 Mole Monitoring Research protocols should include monitoring of existing nevi.
