the bottom line is, whether or not you happen to be using at the time, alcohol use is counterproductive to anabolism in general. there have been countless studies that demonstrate the negative effects of alcohol on the body with regards to maintaining an anabolic environment...
the whole idea when using is to maximize the benefits of the compound taken while minimizing the potential risks. this applies to diet, training, rest, and the avoidance of recreational drugs in general (i include alcohol here).
you must understand that while taking orals your liver will already be working pretty hard, and drinking ma increase your chance of elevating liver values past a healthy point.
this is the difficult choice that the athlete must make- either use and avoid alcohol/drugs OR lessen the effectiveness of your cycle and increase the risk of damage to your body.
i for one refuse to let good drugs that i pay good money for go to waste.
do i get bored sometimes? YES
do i wish i could go out and get shitfaced and chase pussy? YES
but, you can be goddamn sure if i'm going to take the risk of self administering anabolics i'm going to get the most out of it; and if that means sacrificing my social life here and there then so be it. i'll go out when i'm clean.
