I don't want to walk over this man's thread. But tren is said toxic but every liver toxcity test I've seen done barely elevates above normal. Now superdrol elevated me and M1T is similar will do same. But if u take right stuff drink alot of water eat clean your good. And gear is good. I've gained 14 lbs in 4 weeks for a reason and not fat weight. Books are good but just as my college professor said books knowledge will never trump field knowledge.
