i saw many threads on the old

page that talks about the pheromones wearing due to long time saving, so if i bought A314 and only use it not that

often and will it wear out if i leave it for 2-3 years? or even more?
I'm planning to go to a country where i

just cant get by hands to buy them, so i was planning to buy a bulk of them,
a314, a7 and soe, if either one of

them i use and leave it for years will the effect wear out by itself?
