Melanotan I CAS NO.75921-69-6
<p>Melanotan I is a synthetic peptide analog of the α-melanocyte stimulating hormone (α-MSH), renowned for its potent melanogenic properties that stimulate skin tanning. Originally researched for photoprotection, it activates melanocytes to increase eumelanin production, offering a sunless tanning effect and potential benefits for skin conditions like erythropoietic protoporphyria. The product appeals to individuals…

1.MECHANISM OF ACTION
The peptide functions as a non-selective agonist at melanocortin receptors, primarily targeting the MC1R on melanocytes. Upon binding, it triggers intracellular cAMP elevation through G-protein coupled receptor activation, leading to upregulated tyrosinase activity and subsequent melanin synthesis. This receptor-mediated pathway promotes eumelanin production over pheomelanin, resulting in darker pigmentation with potential photoprotective qualities, while also influencing ancillary effects on inflammation and sexual function through cross-reactivity with other melanocortin receptors.

2.PRODUCT INDICATIONS
3.CLINICAL EFFICACY OF PRODUCT
Research demonstrates Melanotan I's capacity to induce significant skin darkening through increased eumelanin production, with studies showing measurable pigmentation changes lasting weeks post-administration. In photodermatosis models, it reduces photosensitivity reactions and minimizes UV-induced damage. Its effects on libido and erectile function observed in early-phase trials, while secondary, contribute to its multifaceted research profile, though variable responses necessitate further investigation into individualized dosing and long-term safety parameters.
