Best-selling product, fast delivery. MT-1 freeze-dried powder raw material, with a purity of 99%. CAS number: 75921-69-6. Sunscreen effect

Melanotan-1, also known as Afamelanotide or MT-1, is a synthetic polypeptide made up of 13 amino acids. Its CAS number is 75921-69-6 and molecular weight is 1646.85. It was first developed by the University of Arizona in 1981 for photoprotection research purposes.

Its molecular structure has two major adjustments derived from a natural melanocyte stimulating peptide: the leucine at position 4 is substituted with methionine, and D-phenylalanine at position 7 is swapped with L-phenylalanine. This adjustment delivers better stability and longer effective time than the natural peptide source.

Induce skin tanning: Stimulate the production of melanin, achieving a long-lasting tanning effect.
Reduce light damage: Reduce the number of sunburned cells caused by ultraviolet rays by approximately 47%.
Preventing phototoxicity: Approved for the prevention of severe allergic reactions to sunlight in patients with erythropoietic protoporphyria.
Collaborative ultraviolet rays: When used in combination with sunlight or UV-B rays, they can significantly enhance the tanning effect and shorten the exposure time required to achieve the desired skin tone.
