Umm, wish I hadn't already gotten into some deep waters from even suggesting it, on top of of the anxiolysis chain, FOR SOME SPECIFIC INDIVIDUALS ESPECIALLY, probably very select few like me, who genuinely, throughout trialing it for a decade at doses of up to 14-16gpd (i know, yes, and no puking, was the top of what I think I could've pushed it and some days were brainfogged a bit, and definitely for what it's known for medically and an approved very profoundly recognized relatively strong anxiolytic in some EU country*
But besides me at 4.5-5.5gpd, I wasn't able to personally see someone take phenibut in real life and experience the whole array of insanely broad NOOTROPIC by the definition suite of effects, literally doing it all, almost, depending on your own desires for it's effects.
Shares the dumb-expotentially insane effects of sleep that is on such rejuvenating, subjectively levels, that equal Bryan Johnsons perfect sleep regimen but could ignore and get the same true "one of the most profound drugs there is for wow - a few good and i mean the genuine good / clean off all even slightly influencing sleep disturbers - good nights sleep", baclofen shares the same non-sleep inducing but once asleep restorative factor of it. But as a somewhat of an RC novice since 2010 and nootropics being half of my obsession, immediately going Cerebroylsin / Cortexin and any nuclear option to restore-enhance cognition levels of dedicaded - Phenibut is practically in the top 5 or even top 3 of any substance ever taken to only have access to on a deserted Island for a lifetime if had to choose.
Quite the shill for it, eh? But I'm "special" in the very non-complimentary ways, as are so many here.
