Melanotan2 10MG
$29.00MG
Melanotan-2 (MT-2) is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH) first developed in the 1980s. Scientific studies suggest that MT-2 may interact with pathways involved in sexual function, behavioral regulation, appetite control, and melanin production. Through its action on melanocytes, it is known to support increased pigmentation in laboratory settings. Early research has also explored MT-2’s potential relevance to neurodevelopmental studies, including preliminary investigations related to autism, though these findings remain exploratory.

Overview
Melanotan 2 represents a revolutionary advancement in melanocortin receptor research. This cyclic heptapeptide analog of α-MSH features a unique lactam bridge structure that enables broad receptor activation across MC1R, MC3R, MC4R, and MC5R. Unlike its linear predecessor Melanotan 1, MT-2’s compact cyclic architecture provides enhanced stability and multi-system biological activity. Originally developed for pigmentation research, MT-2 has emerged as a valuable tool for investigating diverse physiological processes including sexual function, appetite regulation, and energy homeostasis. Its non-selective receptor profile makes it particularly valuable for studying the interconnected nature of melanocortin signaling pathways.
