shelf life of a/s

i was wondering how long everything is good for
does it go bad after half a year or does it not go bad
new here so i have no clue

I have read on this board that as long as its still sterile (Sealed) its probably good for at least 6 months past the date - having said that I would NOT use gear thats out of date, but thats just me being old mister paranoid

after the expiration date the gear is good, but the potency of it happens in decress.
