I started taking it on day 1, and I was kind of following Ginie's program (she followed Chiyo)... I don't really think it's that important if you start on day one or after your menstruation, I mean the girls here that started on day one grew and I belive the ones that started later are growing too.. The instructions that come with PM pills say to start taking on day one....so I guess you just have to experiment and see what happens.
MSM is this:

I bought mine from here:

It's the worst thing I've ever tasted btw, I mix it with juice and take it. It helps with NBE because it helps with connective tissue andd stuff...erm ok not sure but everyone says it helps so give it a try besides it's cheap.

Thank yo for your response how many days do you take PM from day 1? How many mg a day? thanks again
