I think not. There are a lot of "fakes" or websites unaffiliated with Gensci that claim to be, but which the real gensci webpage says is not.
Maybe Gensci is secretly in affiliation with those websites to allow the sale of their hgh to european and U.S. markets? I don't know, but I know for certain that the real Gensci has not changed the name of it's hgh from Jintropin to anything else.
