I have quite alot of products I’ve ordered in the last 18 months; I use some up right away (Instant Sexy, Shine) but others like TAF, TAH, MX135, Instant Openess) I use very sporadically. What is the general shelf life of these products? ---

If you keep them in a cool dark place, at least a couple of years. I have some that are 3 or 4 years old that are still good, they just never did much for me. ---

I left town over the weekend, and left several bottles in a purse in a car. When I got back i realized that they had spent about 5 hours each day in 100+ degree heat (but in the dark). Does this mean the shelf life is shortened on them? ---

I think it only affects them if they’re in sunlight ---

About 140 is where they “die”. Try them out and see if they’re ok. ---

Thanks everyone! I tried them and found that they work fine. I was just worried about the shelf life. ---

I seem to have some luck with pheros that have been Soux vide in warm places, like my pants pocket, or in the car. its summertime here, and I keep my Cttm in my lunchbox pocket, which steeps in the hot car during the 50 min. ride home. this might explain the hits i’ve been getting on the last half of the bottle… maybe the molecules need a bit of heat to finish dispersing into the carrier… I can still smell the pheros in them. shelf life is definitely longer than 6 months. ---

If they are alcohol based which most mones here are they can last years and years when stored properly. In a cool dark place with the bottle sealed. Just like your perfumes. If it is oil based it will break down after about a year. Heat does make the molecules more active which is why we suggest you spray to places on the body that warm up. To much heat will damage them though. Your pants pocket or brief spells in the car are fine. Leaving it on your dash board in the sun on a 90 degree day is not. They will begin to evaporate even in a closed bottle. I have left mones in a heated area and found the bottle almost bone dry when I went to retrieve it even though it was half full when I left it because of evaporation. When you have a spray top bottle its not air tight. Tisha ---

I have some -none from freshman year. I think about 5 or 6 years old. Would that last? Did a test once, but got nothing. Anyone have a [pheromone](https://pheromonelabs.com/shop/) that’s 5+ years old? ---

I have mx235 (I think I bought it last summer so I’ve had it for almost a year and I’ve used it a few days every week) and I still have like almost 1/2 the bottle left lol, and it works fine. Just store it in a cool, dark place 🙂
