Well, this guy is a close friend of mine. I can tell you that he is actually very educated, and incredibly smart.
To clear things up, he went on prohormones as a lack of options when his source dried up. He does know how bad it is for his liver, but he (and I too actually) live by the idea that its better to die big than live small. So, although it may be harming his liver, he is willing to deal with that because of the results it is giving him.
I can't justify the synthol kid though, he actually is a bit of a dumb ass....
