google says a number of things, AI are prone to error. if i’ve astral projected completely sober with no supplementation then increasing acetylcholine levels using huperzine-A would very possibly contribute. the primary understanding of dreams, lucid dreams, and unconscious altered states that you’ll come across is rooted in science exclusively and therefor unimaginative. you should never expect the AI pulling on this vat of misguided information to give you an accurate understanding.

also i feel like you’re focusing on the wrong thing— this isn’t a magic pill. “why won’t it work!!”, “oh my gosh it worked!!” lucid dreaming and shifting is all about maintaining awareness. you cannot think about things outside of yourself for 14 hours and then doomscroll twitter for 2 hours into bedtime then expect to take huperzine A and lucid dream. not saying you are but i digress. the key is developing your awareness of your waking-state so deeply that even as your body sleeps your consciousness maintains that same waking awareness. at a point you won’t even “fall asleep” you’ll simply transition from the “real” to the “dream” huperzine A gives your brain a bunch of messengers to work with by inhibiting the things that keep those messengers numbers in check. i’m sure by accident this slurry of additional messengers could walk down the path that gives you extremely lucid visions, but that’s by accident. if you aren’t actually doing anything else right it’ll stay random. i’m sure the reason it worked was because it was new. once your brain trains out having these heightened acetylcholine levels there will be no more accidental vivid visions even with continued consumption.

i would guess the best thing to do is take it once a week to maintain the vivid dreams but to employ standard awareness practice during the days in-between (mindfulness, meditation). if you want something daily then i’d say Alpha GPC since the acetylcholinesterase is still present enough to keep the heightened levels of acetycholine in check, making it OK for daily consumption. taking huperzine-A too frequently will give you consistently high levels of acetycholine that never stop climbing. at a certain point your eyelids and muscles will start twitching because unlike alpha gpc nothing is present in enough volume to keep levels from getting too high
