Please don't overthink it,
The purpose was for you to better understand what perhaps your goals are,by researching first and then asking questions you'll get a more than a single version of what you are searching for.
I would recommend you check out some of my posts and pics,I give the info based on my results and mistakes,and I made a lot of mistakes.So in efforts to shorten the learning curve,checking out what works and doesn't is great way to start.
One thing I would tell you is when you start NBE is to go slow,I was in such frenzy when I started,after 5 months on just herbs I went to PM,so after that I saw more growth but also stalled it by ramping up my doses.So gradually increasing your dosage is the way to go,build yourself up 3000mg of pm.Most members on PM are on that dose or close to it,but it will take more than just PM.I'll explain that to if you wish.
To fully transition you'll have to consider BO,if that's your goal,you'll find members experience including mine here differ on that,so please relax,enjoy this experience!.....hopefully I'll save you or someone else some time and money....save your $$$$ on black cohosh (more for menopause than for us).
Nothing of what I've said should be taken personally,I apologize if your were offended,I'm here to help.
Good luck

and welcome!
P.S. I'm still newish,I lurked here for months researching,but 12 months of NBE
