Positive experiences
“Phenibut every 3 days. Hands down most effective I've tried. Plus you wake up feeling amazing.”
“Phenibut(10/10): My holy grail of social anxiety relief. The first time I took it was absolutely mind blowing.”
“Work was RIDICULOUSLY busy yesterday, and ordinarily I'd have been flipping my shit, but I didn't. The burnout is gone.”
“Zero tolerance phenibut was literally life-changing in every way. It felt like the limitless drug and made me feel like the most charismatic and capable man on earth.”
“Low dose (~200mg) phenibut daily. It has worked wonders for my ASD-related depression and social difficulties.”
“Taking phenibut with a shitload of caffeine gives me the same feeling as when I stay up for 24+ hours.”
Negative and mixed experiences
“I have been through phenibut withdrawals, I am fairly sure a human cannot experience anything worse.”
“Phenibut was decent, I was able to stay energized but it made me feel a bit manic and is not worth the WD risk.”
“I am feeling the amazing effects of about one gram of phenibut. Work is easier to start, I care less about making mistakes.”
“1.5 grams of Phenibut, which I am tapering down from a high of 2.5 grams... I didn't realize Phenibut was so problematic and addictive. I quickly developed a tolerance... I'm addicted to it and now have to taper off.”
“Unfortunately I abused them and took some high amounts of: phenibut (15 g) + Alpha GPC (5g) + Noopept (150mg) + Aniracetam (15g) in a 12 hour period. Today I was stumbling all over the place, slurring speech, very anxious, feeling dissociate.”
“500mg before sleep for me helps me sleep better. I took 2g before and after a couple of hours I felt a bit drunk, and not in a good way.”
