drinking heavily on cycle is not a good idea, but boozing it up in PCT is even worse.
one drink of something like red wine or a dark beer appears to be healthy for most people, but anything beyond that is not a good idea here. at least an injectable steroid isn't as hard on you as an oral is.
with that being said, you need to keep an eye on Tyenol (acetemetphen), as that's surprisingly hard on the liver....
FWIW, i ran my first cycle (and PCT) when i was in college, and didn't drink the whole 16 weeks.
