Melanotan-II (MT-2) is a cyclic heptapeptide analog of alpha-MSH with potent activity at multiple melanocortin receptors, studied in pigmentation, erectile-function and appetite research. The lactam-bridged cyclic structure confers high receptor affinity and metabolic stability. The material is a white lyophilized powder at >=99% HPLC purity in a sealed vial. Batch-specific analysis, bulk pricing and reliable international delivery are offered for research use. Melanotan-II is a cyclic melanocortin analog studied in receptor-pharmacology research where its affinity across melanocortin receptor subtypes and the resulting functional responses are examined. The cyclic scaffold provides metabolic resistance, supporting consistent activity in extended protocols, and investigators value it as a tool in pigment and receptor studies. The lyophilized material reconstitutes cleanly, and our documentation verifies purity and content. We supply research and bulk quantities with professional packing and responsive support for specifications and delivery. Because the cyclic analog is often compared with linear variants, consistent quality between lots is essential, and our documentation records purity and content for those comparisons. We supply the material with secure packing and storage advice that preserves stability during long protocols. Research and bulk quantities are both available, and our team can coordinate multi-peptide orders with aligned documentation and delivery to simplify study setup. As a factory-connected supplier, we keep stable stock of popular peptides and can accommodate custom pack sizes, OEM labeling and private-label requests. Shipments are handled by experienced logistics partners with secure packing and reliable delivery timelines.
