So I've been reading and hearing about things like tren, deca, PTC, pramypexil(not sure if thats how its spelled) and using insulin with test and all these other terms and/or supplements are confusing the heck out of me . What exactly are these and what other terms should I become familiar with. I'm trying to figure out what Im going to use in a stack for my first cycle so I wan't to know all this stuff before hand.
