Summary

Huperzine A is a naturally occurring compound purified from the plant called Huperzia serrata. It is best known as an inhibitor of an acetylcholinesterase (AChE) enzyme that breaks down the ‘learning neurotransmitter’ acetylcholine.

By preventing the breakdown, huperzine A boosts the levels of available acetylcholine which plays the role in forming new memories, reasoning, concentration, cognition, and neuroplasticity. Huperzine A is thus used as memory and learning enhancer that may also help to protect the brain by reducing free radicals and oxidative stress. As well as to enhance the work of other free radical scavengers.

It also plays a neuroprotective role by protecting brain cells from glutamate toxicity and increases nerve growth factor levels in the brain. Researchers are also investigating huperzine A for protection against chemical warfare nerve agent poisoning.

It should be said that because of the long half-life most neuro-hackers prefer cycling. Cycling of huperzine A tends to be used since it can remain in the body for quite some time (half-life of 10-14 hours), and although a ‘cycle’ of huperzine A tends to last 2-4 weeks followed by a break the optimal cycle length is not yet known.

Further information

Another interesting thing about huperzine A, is that via inhibiting the G4 Isoform of Acetylcholineesterase, it causes increased activation of Alpha 7 Nicotinic Acetylcholine receptors. These receptors regulate inflammatory pathways in the brain.
