There shouldn't be a problem with taking as much PM in a day as you can afford. There is no known lethal dose in animal models. I would avoid taking any after 8pm, because it affects some people - me at least - if it concentrates overnight, in the form of lower back (kidney?) pain. I've found by trial and error that the mental benefits of 1g lasts me about 3 hours, so I assume all other effects last that long. Given that, the most that I have taken in a day without any ill effects have been about 7g (once) 6g (occasionally) 5g(often).

I think while there is no known lethal dose for pm, taking too much pm may overload your estrogen receptors and stall your breast growth and/or induce estrogen dominance.
