I started in the game using Sustanon, and I've never used anything else. Initially I was afraid of pinning, and figured I could hack doing it once a week. At a low dose (250-300mg/week), I've had great results over 2 cycles, and no need to go higher yet.
My next cycle will be Sustanon at 250mg/week, and Tren Ace at 50mg/EOD.
I'm all about sane cycle dosages, and keepable gains.
