its def a no no when on orals. this is due to the harshness on the liver. I suppose VERY responsible moderation would be alright on injectable only cycles (minus inj winstrol, which is still harsh on the liver despite being injectable), however i stay away from it all together when on ANY cycle
so your liver doesnt dissintegrate!!! bit of an exaggeration, but from what i know, thats the main reason, buffdoc should be able to clarify...
i once read that when you drink alcohol, the cells in your liver double in size for a 24 hour period... now think about if you were juicing AND drinking
stay healthy bro, a beer here and there wont kill you, but dont overdo it
