Was considering if necessary to stop PM at 4th week as Robin did to simulate girl cycle or it does not matter specially I am currently at low dosage. Advise?

You're probably going to have to do some self-experimentation to find out how much of an impact, if any, it has on your NBE program. I don't go cold turkey or lower my pm intake beyond a certain threshold, but that's because I want to maintain brain rewiring. It seems my breast growth does just fine without having to simulate a cycle, but I don't know how simulating a cycle would impact my progress.
