If I’m using other pheromones with Androsterone as a booster do they have to by layered together?
The sprays you get from us should always be layered as opposed to mixed together in a bottle. It’s how they are designed according to Michael Harris.
I forget to mention this
I meant do the other pheromones have to be layered with the Androsterone to be boosted?
I would say to be safe, yes - but try it different ways and let us know. 
I did try it once with Instant Gentleman with Akuto layered over A1 a while back.
I tried it again with IG over A1. I was on the bus this girl got on the bus she was sitting near me. When the bus arrived at the subway station. I get up got off the bus I’m going down the stairs I notice she’s behind me. I get down to th platform I walk over a bit to the right she’s there and 10 seconds later it looks like she got on the wrong side of the platform she goes back up the stairs.
I don’t know what to make of it
