You should definately research the ph and the pct for it before you start. there's no point in spending the time and money to run a cycle that you'll make decent gains on, just to turn around and lose them due to a crappy pct... or worse, develope gyno or other unwanted sides. research Pct and what support supps you should take to make the best gains and keep them. you'll be doing the favor for yourself. google "proper pct". That's a good place to start.
