I have wondered the same thing. At the local Vitamin Shoppe there was a sale on their brand of Stinging Nettle 2 bottles of 300 caps for 15.99. I think each cap was 350mg or 450mg of the root. I was wondering if superdosing "beta ActivaTe" style (5-6 caps/4 times a day) would yield any results. I decided against trying it because I was weary about superdosing something like nettle that messes with gender hormones. Obviously Designer Supps isolated the proper extract that would yield positive results for males, but I have no idea if there are other things in that plant that cause hormone fluctuations, especially anything that causes estrogen side-effects. I could have extremely flawed logic on that though as I have only researched Stinging Nettle and its "ActivaTe" extract. Just an observation.
