Expiry: do pheromone colognes go bad, and how long after buying?

Do pheromone colognes expire or do they go bad? If so then when or how long after buying

Dear Friend,

It depends on how you store them.
If you them in cool calm place in proper bottles, labelled and capped properly, then you can use them for years.

?I dont think they expire . I have read it somewhere on this forum that they can used after years (7 or 8, i dont remember exactly), just because they were properly stored.

Hope this helps, alternately you can raise a ticket with store and get exact details .

keep posting, take care
