Very fast working!

Posted by iHerb Customer 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!

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!
