Melanotan-2: a research overview

Melanotan-2 is a synthetic peptide studied in melanocortin-system research. This overview covers its structure and handling for an in-vitro research audience, with no therapeutic or dosing claims.

What it is

Melanotan-2 is a cyclic synthetic peptide analogue related to alpha-melanocyte-stimulating hormone (α-MSH). Its cyclic structure improves stability relative to the natural hormone. It is supplied lyophilised.

Why it is studied

Melanotan-2 appears in preclinical and in-vitro literature involving melanocortin-receptor signalling. The findings belong to those studies; this page makes no claim about effects in humans.

Handling notes

  • Reconstitute gently; never shake.
  • Keep the dry solid sealed, cold and dark.
  • Refrigerate after reconstitution and aliquot to limit freeze-thaw cycles.

For in-vitro research use only. Not for human or veterinary use.
