Instead of mixing them together in a togo, which leaves you with a then unchangable mix that may or may not be useful, you should layer the spray pheros over each other straight from the bottles, leaving a couple of minutes for each layer to dry down. Have a read of this:
That way, you can vary the proportions more easily as you go along - eg adding TUTH when going into a more appropriate/sexually charged environment, or softening an overt mix with IS if needed.
And you do not mix oil with alc-base or apply one over the other, as you will wreck the diffusion of both. Keep these app points apart.
As for your mix - Personally, I’ve found anything involving A314 and MX297/390 together to be highly unproductive. Just sends a confusing signal that failed totally around people who had previously responded very well to one or the other. I’m left wondering if the rone in the A314 might not sit well with the 297/390? Although Ammo has rone, it is also better balanced and lower proportion to begin with. TBH, for sexuality with 297/390, I found TUTH or even plain androstenone the best and least disturbing addition. IS goes well with all of these.
As for dose - we can’t tell you that! This is where you need to do a little legwork tourself to see what sits best with your body chemistry, personality and social situations. Once you have an idea for your major components, it then becomes much easier to determine how they might work together.
