Think you need to research a little more before using.
Look on the forums here, quite a few logs and stuff. After reviewing you need to work out a plan (workout and food) and get that into place a few weeks before you start Nanodrol (if you decide to do it)
I'm no expert but I spent some time reading before I decided to start a cycle. It worked for me. On my last few days of PCT now (remember you need this too) and it's worked out great.
