Huperzine
Other
Impact
High effect
Typical dose:50–400 mcg / day
Huperzine A is a powerful acetylcholinesterase inhibitor, which increases levels of the neurotransmitter acetylcholine, crucial for learning and concentration. Due to its long half-life and potency, it is best used cyclically (e.g., a few days on, a few days off) for specific demanding tasks or projects rather than for daily, continuous supplementation.
