Well, dont count on no sides from the Jintropin. Vovan, one of Ret's buddy's, posted awhile back how when he went up to 8 or 10 IU a day and he couldnt drive his car because of the crazy CTS it gave him. Suffice to say, I have not heard one bad or even mediocre review of Jintropin. All I have heard is great reviews.
