I wouldn't drink a six pack while on gear, although I don't think it is going to be that bad for your health unless you are on a 17aa. It will inhibit some gains though, I have done it and seen the results. As for the replies above, never smoke weed while on, I have friends that said it contributed to gyno, and painkillers, while they are a bad idea while not on, most of them are tough on the liver so I would definitely not combine them with AS use. If you want to have a couple of beers, go ahead, but you are not going to get maximum results from your cycle.
