Expired BAC water - still good?

Not sure if the GHK stuff or something else is making the Botox fade faster — heard metabolism changes can do that. I'm on multiple peptides though, so could be anything.
 
Expired BAC water from a medical setting is still bacteriostatic - the benzyl alcohol doesn't degrade meaningfully past the printed date. The main concern is seal integrity, not the chemistry.
 
The customs flagging question is separate from the expiry one - those are genuinely different concerns. On the expired vials: BAC water in sealed single-use vials tends to stay stable well past the printed date if stored correctly, and medical spa stock in controlled environments is usually fine. The manufacturer date is conservatism, not a hard degradation point.
 
Opened BAC water stored refrigerated - dark doesn't matter much once it's in the fridge. 28-30 days from first puncture is the standard safe window regardless of the printed expiration date.
 
Bacteriostatic water past expiration doesn't fail suddenly - the benzyl alcohol preservative is stable and the water itself doesn't degrade. The expiration is a regulatory date, not a microbial threshold. If seals are intact and storage was cool and dark, it's usable.
