I am glad you finally discovered A314. It really is a life changing product, if there ever was one!
I apply 2-3 drops to the sides of my neck, behind my ears and under my chin. I also wipe the residue on my upper lip. (residue on my finger from rubbing it on my neck!) It helps with self effects. Everyone is different though. Just keep testing and you will find your sweet spot!
Read this post from Tisha it explains the process:
A314 is a well balanced product on its own. I have never tried P79 with it, however I do not believe that in this case P79 will intensify in the way that you are looking for. It is a mix. P79 can intensify effects of another putative. However when you are adding it to a mix, it throws the entire mix off and cause unwanted effects. Hence you feeling like you OD. You can add other products to A314 and get awesome results though. I have never tried P79 and cannot tell you what I had as a result. When I add stuff to A314, I ususally have tested it on its own first to know what the effects should be, then add it to the combo and see how the Putative effects the combo. Sometimes it is good. Sometimes it is bad. It just depends.
