A couple years ago I was hunting at a friend's farm and noticed a deodorant-type applicator stick of Evercalm in their bunk house. Back in the 1990's, I went through a scent testing phase and dumped a bunch of money on products that mostly disappointed, so I stopped buying them for many years. However I had heard the claims of Evercalm "herd in a bottle" and wondered if it actually worked. My friend related that it belonged to his son....who felt it was really effective. The next day the son came over and I asked him about it. He had just purchased a new stick and handed me the one that was about 2/3 gone to try for myself. I tried it without any conclusive evidence and then put it in a ziplock baggie....and promptly lost track of it until this afternoon. Thus my question.....in the stick form....is it stabilized enough to still be good two years later?
