I love oil based products. They seem to last longer than alcohol based ones. I do not believe that the 45 degree temp will have any negative impact on your A314.
As to your other questions, as a primer, pheromones react differently on each and every individual. Because your body naturally produces its own pheromones, you have your own unique canvas to work with.
Most products seem to add to A314’s effects in a positive manner. That is part of what I think makes it so great. Using IS adds its effects to A314. Ammo, is one product I have not really had a lot of experience in conjunction with A314. I am married and really not trying to pick up females. A314, while primarily Rone does contain None, which is the main phero in Ammo. Basically you are raising the None content. I have used A314, IJ, and IO as a combo. I really enjoyed that as a combo. It upped my feelings of personal power, and others really realized I was a force to be reckoned with.
Follow the advice contained in this thread for learning how to test your pheromones. It is the most basic thing that most people seem to skip over and then have no response or just mediocre responses.
Again any questions feel free to ask!
