Question: how much huperzine a to take?
Answer: Recommended Dosage Huperzine A supplementation tends to be in the range of 50 - 200 mcg daily. Our tablets are 200 mcg each, but can be easily broken into halves or quarters for those wishing to take smaller doses. Huperzine A has a long half-life (10-14 hours), so cycling this product is often recommended.
