Research applications

Melanotan II was developed by Hruby, Hadley, and colleagues at the University of Arizona in the 1980s. The seminal Phase I clinical study is Dorr et al. (Life Sciences, 1996; PMID 8637402), a pilot trial in three healthy male volunteers that documented dose-dependent pigmentation together with nausea, a 'stretching and yawning complex,' and spontaneous penile erections — the MC4R sexual-arousal signal that later motivated the development of bremelanotide (PT-141/Vyleesi). MT-II itself was never advanced to Phase III and has never received regulatory approval in any jurisdiction. As unregulated consumer use expanded through the 2000s, dermatology literature accumulated safety signals: Langan et al. (BMJ 2009, PMID 19174439) reported changes in moles among young users of unlicensed 'sun tan jab' preparations; Cardones & Grichnik (Arch Dermatol 2009, PMID 19380666) described alpha-MSH-induced eruptive atypical nevi in a patient with dysplastic nevi and prior melanoma who used MT-II; Evans-Brown et al. (BMJ 2009, PMID 19224885) documented widespread unregulated population use. Further case reports describe new primary cutaneous melanoma in young MT-II users and rare rhabdomyolysis. Regulators (FDA, UK MHRA, Australian TGA) have explicitly warned against use. Note: the Barnetson et al. 2006 photoprotection study (J Invest Dermatol, PMID 16763547) evaluated the related linear analog [Nle4-D-Phe7]-alpha-MSH (afamelanotide / Melanotan-I), not MT-II. Category 2 classification reflects documented safety concerns from non-selective melanocortin activation combined with oncologic signals.
