Best thing for you to do is a search on the forum. If your not plat. then the search isn't the best. Anyhow I would recommend stacking the two together. 500mg sust, 300 mg deca week. If you were doing one or the other, I suggest doing Test. I don't want to have to worry about things like "Deca dick" on my first cycle. It has been said that Deca also shuts you down like nothing else. Welcome to the dark side. You have just began your journey. Do your home work before anything else. Good Luck Buddy.
