How much (mgs) are you going to use? How much shots are you going to do per week?
As yogi just said, you need to think about AI and PCT. AI is dependent on the person and the amount of test (Sust in your case). Water retention may happen as a side of E1/ E2 elevation, if don't use AI. I like Anas to control E2, but there are evidence of examestane reducing E1 plus E2. It looks like you need a little more research about what you are going to do... that's why you are here, I suppose... don't take me wrong, you are lacking too much info. Acne, you are going to have it if you are prone to, you can control a little bit by using AI, but not scape from it, since you a prone.
Muscles, hummm... forget it, you are going to lose everything with time, maybe hold a little bit of it. You cannot keep muscles made with steroids without steroids, simple.
