Before you get on any drugs you should make sure your diet and workout program are consistent and squared away. Otherwise you are just going to cheat yourself out of results and, essentially, wasting money on gear. Everything needs to be in line if you want to get the most out of whatever you are pinning.
Also, if you used to lift alot but stopped.... Your body is green to the gym even though you might know what you are doing. That is a main reason why you should get everything consistent and working right before you throw some drugs in your system. Get your body back on track with training for an extended period of time first. Your risk for injury goes way up if you go in the gym after a long time and you are running a cycle. Sounds like a nice pec or bicep tear to me.
