Yup - always keep oils and sprays apart. It is ok to layer sprays together though, just leave a minute or two between each layer for the alcohol to evaporate.
As for app points, lots of good places and you can get oils on spots not easy to spray. See this thread:
But don’t get too hung up on app points, so long as it has good circulation and is open to the air, it’s viable.
Now start again but maybe at a lower dose for each, what is your work day dose of A 314? Maybe start by upping that by 50% and one spray of TUTH. Then you can vary each one depending on result.
If you have some Ammo, try 1 or 2 sprays with just one drop A314. That seems to do quite well for younger guys/girls as Ammo has better/broader balance
