Why is Halotestin among the choices? Halotestin is not useful nor practical for bulking purposes. That being said, I love Halo for hardness and strength gains.
Syntex (Syntax?) Anadrol-50 from the mid-1990s blew me up OVERNIGHT. And I hardly even ate at the time. Lots of protein, yes, but not much in the way of calories. Lots of strength increase as well as water retention but the "Animal Mother" of all instant-bulkers for me.
Bodybuilding is about learning to maximally contract a muscle. It is not about lifting weight. The best bodybuilders in the world are that way because they can contract their muscle harder than you, NOT because they lift more.
