At the end of the year (probably between September and December), I am planning on moving out of the suburban area and into an apartment downtown.
I was planning on buying pheromones now, storing them in my closet and leaving them until I move. So, this way, if I buy pheromones every few weeks, by the time I move out, I would have a pretty good supply.
If I buy pheromones now and go with this plan, will they last that long?
I read somewhere on this forum, that If Stored properly (at cool dry place, well packed, leak proof) then shelf life is not less than 2 years.
Few friends reported, their stuff potent and active even longer than this. Only thing is to be stored properly.
With room temperature/dark storage, they last for years. Oils may not last as well as sprays but I’ve never had a problem with AD products going-off at all (other firms yes 
). Some MX sprays can darken slightly with time but still remain perfectly usable. Dark storage is IMO more important than outright coolness as light will degrade pheros faster than tempratires - although scents will likely suffer first in hot conditions.
If you do have a product go-off on you, its pretty obvious - They smell sour/rank and often develop white gunk that swirls around when you shake them.
Bumping for question..
One of the sprays on my bottle is spraying very weak, so I was thinking of using a sprayer from an old bottle, only it is a different pheromone. So I was thinking of leaving the sprayer off exposed to air and light for a few days so the pheromones and alcohol can evaporate and break down.
How long should I wait for the pheromones to be gone?
By the way, it is a -none based product the sprayer is coming from. (TUTH)
