  • Research use only

Melanotan-2 is a synthetic cyclic heptapeptide analogue of α-MSH characterised in the literature as a non-selective melanocortin receptor agonist with activity at MC1R, MC3R, MC4R and MC5R. Supplied as lyophilised powder for in-vitro research use only.

The above describes how this compound is characterised in the published peer-reviewed literature. It is not a claim about effects in humans.

Laboratory Handling

Melanotan 2 (MT-2) is supplied as a lyophilised (freeze-dried) powder in a sealed glass vial. For laboratory reconstitution, add the desired volume of diluent (typically bacteriostatic water) slowly down the side wall of the vial. Swirl gently until fully dissolved - do not vortex or shake. Store reconstituted solutions at 2–8 °C and use within 4–6 weeks.

Use our Reconstitution Volume Calculator to compute the resulting mg/ml concentration.
