Researchers sourcing Melanotan II for preclinical studies need a supplier that provides consistent quality and clear documentation for a cyclic peptide with broad melanocortin receptor activity. MT-2 is chemically and pharmacologically distinct from MT-1, and research grade supply has to reflect those distinctions in labeling and documentation. This guide covers supplier evaluation criteria and shows how Midwest Peptide meets those criteria.

Frequently Asked Questions
What is Melanotan II in research contexts?
+
Melanotan II is a synthetic cyclic heptapeptide non-selective melanocortin receptor agonist that binds MC1R, MC3R, MC4R, and MC5R. It is studied in preclinical research for pigmentation, central appetite signaling, and melanocortin pharmacology.
What should researchers verify when sourcing Melanotan II?
+
Verify HPLC purity above 98%, mass spec identity confirming the cyclic 7-amino-acid sequence with the lactam bridge, peptide content quantification, endotoxin testing, and a recent batch-specific COA. Cyclization integrity is critical for proper receptor binding.
Where can research labs source verified Melanotan II?
+
Midwest Peptide supplies research-grade Melanotan II (MT-2) with comprehensive COA documentation, HPLC purity verification, mass spec identity confirmation of the cyclic structure, and lot tracking for reproducible melanocortin pharmacology research.
Is Melanotan II approved for human use?
+
No. Melanotan II is not approved by the FDA for any human therapeutic use. It is supplied strictly for in-vitro and preclinical research purposes by qualified investigators.
Glossary
Key terms used in this article.
- MC1R
- Melanocortin 1 receptor, the GPCR on melanocytes mediating pigmentation effects of melanocortin agonists.
- MC4R
- Melanocortin 4 receptor, primarily expressed in the hypothalamus and central nervous system, regulating appetite and sexual behavior.
- MC5R
- Melanocortin 5 receptor, broadly distributed and implicated in exocrine function and lipolysis.
- Cyclic Peptide
- A peptide whose backbone or side chains are joined into a ring, conferring increased stability and receptor selectivity.
- Bremelanotide
- A cyclic melanocortin agonist analog of Melanotan II with reduced MC1R activity, studied for central effects.
- Lactam Bridge
- An amide bond between side chains that creates the cyclic backbone of Melanotan II, replacing the disulfide bridge of the original alpha-MSH cyclic analogs.
- Cyclization
- The formation of a ring structure in a peptide, conferring increased stability and modified receptor selectivity.
