Melanotan II (MT2)
Melanotan II (MT2) is a synthetic cyclic heptapeptide analog of the naturally occurring alpha-melanocyte-stimulating hormone (a-MSH). It is supplied by Reta Pharma strictly for laboratory research use.
What is MT2?
Developed initially at the University of Arizona, Melanotan II is structurally similar to alpha-MSH, a hormone involved in melanogenesis (the production of melanin). In laboratory settings, MT2 acts as a non-selective agonist of the melanocortin receptors (MC1, MC3, MC4, and MC5).
Research Applications
In in-vitro and in-vivo animal models, MT2 is utilized by researchers investigating:
- Melanocortin receptor binding affinities
- Pathways related to melanogenesis and pigmentation
- Energy homeostasis and feeding behavior (via MC4 receptor interactions)
- Sexual arousal mechanisms in laboratory models
Safety & Regulatory Information
Important: Melanotan II is not an approved medicine. It has not been approved by regulatory bodies (such as the MHRA in the UK or the FDA in the US) for human use.
Reta Pharma supplies high-purity MT2 for research and human consumption, or therapeutic use.
