I suggest always starting with the standard regular concentration until you know for sure your dosage. Its always easier to work up with dose then try to dilute of do half sprays.
However since you 45 you should be fine with 2X with what you listed, even with the AMMO and I suggest for P83 the 12.5 mcg and 25mcg for TAA.
Yeah I think I remember someone saying they didn’t like that TUTH is always people’s “first” but it was mine and it was the one that “proved it worked” to me. Plus, I mean cmon it’s always handy.
