I believe it will be a couple of years before pt141 becomes available, despite all the research on melanotan. I was fortunate to have the opportunity to try melanotan II last year for tanning purposes. Being redheaded it gave some help in the tanning department but not enough of a cost/benefit ratio for me. Had an overall rise in everyday mood with a slight rise in sexual desire. However I was on vacation so this might explain the mental results. After two weeks of taking in I began to have spontaneous erections frequently i.e. every time the wind blew or a reasonably attractive woman was in sight (this is not good in a public beach environment). This lasted for about 2-3 days till my system balanced out. Staying power increased and I had a little trouble reaching orgasm if I had been drinking hard liquor, but not with beer. Also was good for sex 4 times a day for about a week although desire tapered back to normal after the 4th day. I will try it again as I think I was underdosing myself, but it is expensive and hard to find.
