Never seen that happen, the androgens are dissolved prior to sale so what you are getting is a liquid solution, my understanding is that they readily get absorbed into liquid (never heard of them cyrstallising in normal human sweat - the source of natural pheromones that have been isolated in the lab and put into the products as synthetic versions)
So no it should be fine. Just dont take to long exposure to air over a long period can weaken the products so a maximum of five mintues to ten minutes mixing should ensure no problems.
I hope that this helps, but if stored in the appropriate manner of course it should be AOK.
