Thank you Diana! 
 
I used Saw Palmetto during my first four months of NBE.  I haven't used it with pm.  I prefer to use spearmint instead of Saw Palmetto as an anti-androgen.  I think spearmint tastes much better and I find it to be very effective with minimizing my libidio.  
I'm no longer taking 4,000 mg of pm.  I figure for most, if not all genetic females that would be an insanely high dose.  I'm down to a daily dose of 2,000-2,500 mg of pm.  The reason why I was taking higher doses wasn't to boost growth but rather to maintain brain rewiring.  I think 2,000 mg is about all I need for growth.
I think the biggest benefit I get from progesterone cream is preventing estrogen dominance.
