you can get the drug, but not for human consumption (though you can use it if you like) but be warned it is really really pricey
go take a look at melanotan.org in the forums, you get a bunch of guys using this stuff- they also use the cyclic version (melanotan 2) but its a bit harder to get from memory
personally i think you should just wait. its still a pain in the ass, you will need very very regular shots, its fucking expensive (even though i said that, im saying it again) and overall the gains arent really taht phenomenal.
let the pros work on a decent delivery system, probably in the form of an implant, and then use it. the price should come down to something human by then too, not the 300 dollar a week or whatever insane amount of money it costs just now
i ahve to say, if i was a dodgy bastrd in china, i would be making this stuff by the kilogram, theres so much money to be made from people who just cant wat. good thing im legit lol, but DAMN have a lot of people quizzed me about this drug!
