Huperzine A is a natural alkaloid extracted from the Huperzia serrata moss, used for centuries in Chinese pharmacopoeia to support memory. Its uniqueness: it is one of the most potent natural inhibitors of acetylcholinesterase, the enzyme that breaks down acetylcholine — the central neurotransmitter for memory and learning.
By preserving acetylcholine longer in the synaptic cleft, Huperzine A supports synaptic plasticity: neural connections form more easily, new information anchors faster, and focus holds over time. That's why it has become the go-to nootropic for students during exam season, researchers, and anyone who needs to absorb dense information quickly.
Why 200 mcg? This is the dose studied in most clinical trials, the sweet spot for efficacy and tolerance. More doesn't help — and can saturate cholinergic receptors. Our Huperzine A is purified to over 99% by HPLC, free of contaminants and residual solvents.
Cycling is required. Unlike most nootropics, Huperzine A demands a protocol: 5 days ON / 2 days OFF, or 3 weeks ON / 1 week OFF. This rotation maintains cholinergic receptor sensitivity long-term. The result: stable effects week after week, without tolerance buildup.
