Melanotan I (Melanotan-1) is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH) studied in melanocortin receptor research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Melanotan I is investigated in research on melanocortin receptor signaling, pigmentation pathways and related cellular mechanisms, and is commonly applied in cell-based and preclinical studies. The freeze-dried format ensures high stability and easy reconstitution for reproducible 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.
