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 used in receptor-pharmacology work where investigators examine affinity across receptor subtypes and the functional responses that follow, and its cyclic scaffold is the feature that keeps it stable in extended protocols. It is a common tool in pigment and receptor studies, and the lyophilized material reconstitutes cleanly for dose-response work. Our records verify purity and content, and we can supply matched vials from one lot for multi-group designs, with delivery within recommended conditions. This analog dissolves cleanly for dose-response work, and the batch sheet records purity and content for receptor studies. Matched vials from one lot support multi-group designs, and we can bundle related melanocortin analogs in one order when the protocol compares them. Delivery is arranged within recommended conditions, and bulk supply is available. 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.
