MT-2 (Melanotan II Acetate) is a synthetic cyclic heptapeptide analogue of alpha-MSH studied in melanocortin receptor and cosmetic research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. MT-2 is investigated in research on melanocortin signaling, pigment pathways and receptor pharmacology, and is commonly applied in cell-based and preclinical studies. The freeze-dried presentation provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch passes strict quality control, and a Certificate of Analysis is available for specific batches on request. For storage keep the unopened vial sealed at 2-8 degree C protected from light and moisture; for long-term storage store at -20 degree C and avoid repeated freeze-thaw cycles.
