Keypro Anatrol

I am thinking about taking a course of pro hormones, I have been looking at Keypro Anatrol.

I must admit I find a lot of the information I read about pro hormones a little hard to get my pea brain around and although I have been knocking around T-Nation for a while (reading everything I possible can) I still feel a little out of my depth when it comes to the science of nutrition and supplements�?�

Anyway, any advice or links would be greatly appreciated.
