How long do these last - both in the glass bottles and the to-go sizes? Is there an optimal time frame in which to use them?
Thanks!:o
Nope. Pheros will last for ages, so long as you store them in the dark.
Its exposure to light that will do for them fastest.
I think mine are over 3 years old (at least) threw the big bottles away, but just found some to go bottles that were never unwrapped from original envelope.
thanks.
That should be just fine.
Sometimes they can go a light brown/yellow colour after a few months but performance is unaffected. 
The shelf life of our pheromones are about 3 years but if you take care of your pheromones they can last and be good for even longer.
I know that persons like Tish have had their mones ever since AD opened their doors and it is still good to go.
Yep as long as you didnt leave them layig around in the sun they are fine. You would know to because when you do they evaporate.
I think some of mine work even better after I have let them cure longer.
Oil mixes on the othe tend to either go mildly rancid or just lose there klick the longer you have them. Depends on where you got he oil mix to because some vendors use EO’s more able to preseves the oil.

Thank you for your specific answer! Just received my new instant sexiness. Was sent a spray sample of p-130…What does that do? Thanks!
Can I assume it will last for 10 years provided storing it in dark drawer? I suppose ages means at least that…3 years is very short time…
I’ve seen people on here using 7/8yr old pheros that have been properly stored without problem, so yes probably.
If you store them correctly they last many years. They don’t have an expiration date. The alcohol preserves them. Of course the key is storing them correctly. Cool dark place, upright with the cap secured. Keep in mind AD may have a policy of a shelf life of 3 years but that is because they want to sell you the best possible product and there are various guidelines in the industry they need to follow.
3 years is the standard for oil based products.
I find mine get better with age almost like a fine wine. I have products that are well over 5 years old that still rock. Oils tend to separate over time though.

wine gets better with age…does every product from AD has alcohol?
Yes all of them except the oil based products like A314. I do think they add something to preserve into A314 though.
