So a friend gave me some phenibut free amino acid powder to try it out, and then I bought some for myself to further experiment.
I've been using it 1-2 times per week for about 6 weeks now, and I'm very pleased with the effects.
I take about 750-1000 mg each time. Because it's the free amino acid version I take it sublingually and then wash it down after about 5 minutes.
It takes about an hour for the effects to become pronounced, and they steadily increase until about 3.5 hours where they plateau for another 3 hours or so.
The effects I experience include a solid sense of calm, things that would typically bother me don't even phase me. Also I feel care-free and sociable, wanting to make others laugh and feel good about themselves. It does give a slight drunk feeling, but with no motor or visual impairment. It basically erases self-conscious thoughts, I just am able to act like myself without fear of how I'll be received or perceived. It makes me less fearful of my own emotions, and therefore able to contemplate and sort through things I typically bury within myself, and let out a healthy cry, if needed.
You do need to be careful not to take it in excess or too many days in a row. I also take L-Theanine daily (800 mg, 3x/day) and the two mix wonderfully, I recommend trying it out. I also started taking ashwagandha, effective but very mild in comparison, so I have other things to get me through the non-phenibut days.
I get my Phenibut and L-Theanine from Liftmode, I've bought my L-Theanine from them for years now, their products are excellent quality and they're shipping is fast and reliable. I recommend them highly.
