What is Melanotan and Melanotan II?
Based upon a quote of the Arizona Cancer Center found at sunless.com (on June 14th,1999): Melanotan and Melanotan II are both synthetic versions of melanocyte stimulating hormone that were created, synthesized and developed at The University of Arizona and the Arizona Cancer Center. Melanotan is a linear, full length peptide (containing all 13 amino acids). Melanotan II is a shortened, circular version of the same peptide. Both Melanotan and Melanotan II have sunless tanning capabilities but because Melanotan II had labido enhancement and spontaneous erections as side effects, it is now being developed as a sexual and erectile dysfunction drug. To be particularly clear regarding Melanotan (due to previous incorrect news reports) it should be known that it does not cause sexual arousal nor have erectile effects. These aspects are only found in Melanotan II and Bremelanotide. Melanotan.
