So I stepped back from the whole phero thing for a while (a few years). I have a bottle of A314 which is about ⅓ full. I’m thinking I may need to buy another bottle 
The batch date is 2011. Anyone know if this stuff still works? Or is it toast?
Should I use MORE to compensate for any breakdown?
Thanks!!

It should be fine.
So long as there is no contamination, A314’s dark bottle ensures the mones keep for years.
That’s reassuring haha. I’ve kept them I’m my sock drawer too. I hear that the light is bad for them?
Yup, light probably more damaging than anything else - Esp togos or any non-coloured container.
Sounds like they will be just fine.
