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. Melanotan-II is a cyclic melanocortin analog studied in receptor-pharmacology work where investigators examine its affinity across receptor subtypes and the resulting functional responses, and the cyclic scaffold resists degradation in extended protocols. It is a common tool in pigment and receptor studies. The lyophilized material reconstitutes cleanly, and our records verify purity and content. Research and bulk quantities are available. Melanotan-II is provided with full purity documentation, and the lyophilized cyclic peptide reconstitutes readily for receptor assays. We can supply matched vials from one lot for multi-group designs and match packing to the shipping route so the peptide remains stable end to end. All products are manufactured under controlled conditions and released only after purity verification. We welcome small and large orders alike, provide professional packing and fast worldwide dispatch, and offer steady supply to research institutions, labs and trading partners.
