Melanotan II is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone 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 II is investigated in research on melanocortin signaling, pigment pathways and receptor pharmacology, and is commonly applied in cell-based and preclinical studies. The lyophilized format provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only. The cyclic scaffold provides high melanocortin-receptor potency, and researchers study its activity across receptor subtypes in pigmentation and behavioral research. The defined structure supports reproducible synthesis. Each vial contains lyophilized powder with confirmed purity. As a specialized research-grade supplier, we keep a broad peptide portfolio in regular production, which shortens lead times for popular items and enables mixed shipments. OEM and private-label services are available for established buyers, and neutral packaging can be arranged for discreet delivery.
