There's always a possibilty of something goin wrong, in this case with M1T, it can be anything from your liver to the thing you mentioned.
Also, at 5mg I doubt you would see any significant gains. But at our young age, our levels are very high to begin with. Bottom line kid, if your goin do it, at least be smart about it. Dont come here and ask people to convince you that taking the drug is completely safe, cause its not.
