Melanotan II (MT-II) FAQ: Your Research Questions Answered

Introduction

Melanotan II (MT-II) has become one of the most talked-about research peptides thanks to its unique effects on pigmentation, appetite, and sexual function. To help clarify the basics, here are answers to some of the most frequently asked questions about MT-II.

What is Melanotan II (MT-II)?

MT-II is a synthetic peptide analogue of the naturally occurring hormone alpha-MSH (α-melanocyte stimulating hormone). It works by activating melanocortin receptors, which influence pigmentation, appetite, and sexual function.

Why is MT-II called the “tanning peptide”?

MT-II stimulates melanocytes in the skin to produce more melanin, the pigment responsible for skin color. In research studies, this has been shown to cause tanning effects even without sun exposure.

What are the main research areas for MT-II?

  • Pigmentation research → Understanding how melanin pathways are regulated.

  • Metabolism studies → Investigating effects on appetite suppression and energy balance.

  • Sexual function research → Exploring MT-II’s influence on libido via melanocortin pathways.

Is MT-II safe for human use?

No — MT-II is not approved for medical or consumer use. Regulatory bodies like the FDA and MHRA warn against unregulated consumer access, particularly through tanning sprays and injections sold online.

What side effects have been reported in studies?

  • Flushing or redness.

  • Nausea.

  • Darkening of moles and freckles.

  • Changes in appetite or libido.

These findings are based on research models and early human trials.

Is MT-II legal in the UK?

  • MT-II cannot be sold as a supplement or tanning product.

  • It is available only for laboratory research purposes.

  • Any supplier making consumer-facing claims is not compliant with MHRA guidelines.

Where can researchers source MT-II?

Researchers should only source MT-II from trusted suppliers offering research-grade peptides with verified purity.
