Half-life of Huperzine

The half-life of huperzine is about 3 hours. This means it will have an effect that lasts longer than prescription meds (like tacrine and physostigmine ) that do the same thing (boost acetylcholine, a major neurotransmitter that helps focus and memory).

Another remarkable advantage and benefit of huperzine is that it is very selective, acting primarily on acetylcholine in the brain and not elswhere in the body, thereby avoiding unwanted side effects that are seen with prescription medications. In addition, huperzine promotes the outgrowth of neurons, facilitating brain power.
