Melanotan-I (MT-1) is a linear 13-amino-acid analog of alpha-melanocyte-stimulating hormone designed for prolonged activation of the melanocortin-1 receptor, making it a research tool in pigmentation and photobiology studies. The linear structure retains native receptor selectivity while improving resistance to degradation, enabling reproducible dose-response evaluations in cell and animal models. This product is a white lyophilized powder at verified purity in a sealed vial, and quality documentation accompanies every order. Each batch is released only after peptide-content verification and purity assessment, and the corresponding records are retained for future reference. For projects requiring independent confirmation, we can arrange third-party analytical testing and share the results before shipment on request.

Melanotan-I (MT-1) is a linear 13-amino-acid analog of alpha-melanocyte-stimulating hormone, its structure a delicate chain of amino acids that mimics the natural hormone with subtle yet purposeful modifications. Designed for prolonged activation of the melanocortin-1 receptor, it lingers in the body like a persistent whisper, gently and continuously engaging the receptor to amplify its effects. This extended interaction transforms it into a valuable research tool, illuminating the intricate pathways of pigmentation and the complex dance of light and biology in photobiology studies. In the controlled environment of a laboratory, MT-1 becomes a key player, helping scientists unravel the mysteries of how skin tans, how melanocytes respond to stimuli, and how light influences cellular processes, all while adding layers of depth to our understanding of these fundamental biological phenomena.
