Very fast working!

Posted by Reviewer1818192 on Dec 25, 2011 | Verified Purchase

Huperzine Rx-Brain works for me in less than an hour. VERY powerful and I have to take only half of the pill for 3 days in a raw, then make a break, for liver relief (it starts hurting). Then I can take it again and it really helps to use my mind, restore short term memory and improve my mood. Great product. I haven't found so far nothing better working than that, just be aware of the dosage.

Thanks for your feedback!

Well please with product not the way pack in bottle.

Huperzine worked great. I only used one bottle and haven't re-upped yet but I did notice an improvement in mental clarity, focus, sharpness, and energy. Good product.

Thanks for your feedback!
