The whole Androtics line assumes the skin as a chalkboard. It does work. However, trying to duplicate MX200 or ICM is real difficult in a club with layering. People asked for MX200 formula and ICM. They released. But you’ll not make these layering without many, many sprays. I really don’t see someone layering MX200 in public. But, mixing “wrong” or out of step with tradition? Sure wasn’t wrong back then. No telling what changed. If I want a precise amount of 75, I can’t get it in spray without mixing. I have to pre-dilute everything down. But you can get three products in one strength and change your ratios sprayed into a TOGO. 4:1:1 or 1:1:1 or 1:1:4. I do this all the time. I’ve tested 6 different T A C, 75 and None ratios. Can’t do it layering. If you want it down to .25 mcg precise, nothing else works for me. In MX200, it’s all multiples and ratios. 1:1, 1:40 and 1:10.
