Do pheromone products expire?

[**DONOTDELETE**]

I have a bottle of APC that I\'ve had for over 2 years. Do phermones become weaker over time? Will my bottle of APC be weaker now?

Also, has anyone tried wearing a whole bunch of pheromone products at once? I have AE, the Edge, PF, and the old bottle of APC? Would wearing them all at once be overkill?

Any answers to these questions would be appreciated. Thanks.

I\'ve tried thatne part AE + one part APC + one part Edge + one part PF. I mixed them all together in one 5ml bottle and added one drop jasmine e-oil/2ml. It smells very fresh and three dabs is not overkill. It works, but I can\'t say I noticed anything special.
