What people say about Huperzine a and sleep
“Huperzine-A - I initially took it for lucid dreaming, but it is a complete flop for me. Nothing changed. No vivid dreams, no brain function improvement. Nothing.”
“Huperzine A is absolutely magical for me... It increases REM phase of sleep => longer and more vivid dreams & feeling more recharged in the morning.”
“Huperzine A works for me. Restores sensitivity to modafinil, nicotine. Phenibut. 100-200mcg used the day before. Next day sensitivity is higher and tolerance lower.”
“I have had positive experiences using Huperzine-A. ... focus and recall ... AMAZING sleep with super vivid dreams.”
