Ive got drunk on a cycle several times (and by drunk i mean literally drunk, heavy drinking). (injectables cycle only). No it wont kill you, but it's not good for you either. Personally i believe it wont hurt once in a while, but doing it pretty often is not good. Also the thing is, while you are on a cycle you probably already have elevated mood, so you dont need much alcohol. But never mix 17aa steroids and alcohol, that's stupidity and irresponsibility.
