If you have to ask that many questions, it means you have no business messing with them right now. You need to do your own research on all the different compounds! Dosages, etc...and all the negatives and side effects that come with it.
You need to have a good understanding of what to run on cycle to prevent or reduce side effects. You need to have a good understanding of PCT and what you need to run to have a successful one..
Cycles are nothing to take lightly and nobody is going to spoonfeed you everything.
