I have 50.0 mcg/spray concentration of Androsterone and 2.5 mcg/spray concentration of TAH… can’t use the Androsterone straight.
I’ve been thinking about this too, but, darn… there is no information on what is a good dosage of Androsterone that I’ve been able to find.
I guess I’ll be doing some dilutions and starting out very light… prolly around 2.5 mcg/spray and try a 1:1 dose of Rone/TAH.
Should be FUN.

About the TAF longevity… I have a theory about this. I think some of these molecules set off neurotransmitter cascades. And that is what is long-lasting, rather than the pheromone itself. I think these things really do reset you to operate in another frame, another fashion. It is like, when you turn on a light switch, the light comes on. You don’t have to stand there holding the switch in the up position. It stays there once it is switched on. I think TAF is like that to some extent.
