I drink every weekend and I am one of the biggest and strongest guys at my gym. Also relatively lean for a 32 year old boomer.

It does not hurt gains that much. Just look at the college football players who are full blown alcoholics.

Truly though, if you never go out drinking then what the fuck is even the purpose of getting jacked? You are a gymcel loser if you never go out on the prowl to party fuck and fight.
