I re read this and thought maybe the alcohol diffusion is affecting the alpha status for your job. Now If that’s the case, as Jasmin pointed out that 1 spray of 247 is approx 1 drop of A314, but I know A314 diffuses slowly so could it be the same as OD on the A314 because it is alcohol based. Did you try adding more IS to the mix as a 4:1 ratio like the previous post?
I’m curious as to what would happen. I’ll make a topic for this and see if some of the more seasons pheromone users can show any inputs.
