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. Strict quality control is maintained on every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. For laboratory research use only, not for human or veterinary application.
