In my experience with p96, I wouldn’t call it a mental disinhibitor. I’d call it more of an emotional stimulator. Just enough of it, and you’re making puppy-dog eyes at each other. Too much of it, and the more emotionally vulnerable people in the room will be sobbing into their tissues. I like using it with IH to try and stabilize the emotional effect, and p130 helps to steer it away from the effects of personal stress. But DON’T use it in an environment when emotional engagement isn’t safe/appropriate!
I’ve also heard from some of the guys that p96’s emotional effects can be a bit castrating. So read up/experiment on that so you don’t negate your own goals.
And yes, it’s definitely a slow burner.
