Hi i left my phero’s in the centre arm compartment of my car for a few weeks and the sun was beatin down quite heavily. Does heat break down the phero’s in anyway?
Generally the advice for perfumes and various complex chemicals is to store them in a cool dark place to inhibit degradation. That’s why they are often sold in dark glass bottles, to keep light out.
I wouldn’t advise storage in the car.
What I do is decant into to-go bottles. The bulk of the product stays in a cool dark cabinet. The to-go bottle might be subject to more extremes of temperature, but it contains a small amount of product and is used relatively quickly.
i have done this on several occasions 
although i hear its terrible to do, androtics mixes have maintained their usefulness afterwards.
this was in florida ( 90+ heat)
Gettin my hair done tomorrow so i’ll post if the phero’s still work, i haven’t used them for the past few weeks.
