LONGECITY

I recently purchased Ashwagandha capsules with 1.5% withanolides.  The indications on the bottle state to take it 1-2 times a day.  This is not consistent with the Nootropics FAQS page, stating the recommended dosage as 600mg-1200mg ashwagandha root extract standardized to contain ~5% withanolides per day divided equally throughout the day into 2 doses.  It would seem that 4 of the capsules that I purchased would contain about the same amount of withanolides.  Any advice?  

  Also, I read that bacopa should not be stacked with other adaptogens, but it seems that many people are doing it. Does anybody know why it is not recommended?  I was considering stacking rhodiola rosea, bacopa, and ashwagandha.

Thanks!
