Experience:400mg and 300mg of fluorophenibut

My friend and I acquired some fluorophenibut (4-Amino-3-(4-fluorophenyl)butanoic acid) and decided to test it out ourselves as it seemed very promising. We could barely find any information about this substance online (besides some forum and Reddit posts). After doing a bit of research, we were able to work out the recommended dosage. Some users reported that 200mg fluoro-phenibut was equal to about 2 grams of phenibut. At 3:30PM, I dosed out 400mg for myself and 300mg for my friend, hoping that my dosage would be equal in potency to about 4 grams of phenibut (which was my go-to recreational dose).

We were very pleased to find that we could feel the effects of the substance within only 20 minutes which is a huge upgrade to regular phenibut (since it can take more than five hours to kick in). We both felt a strong euphoric body high and physical euphoria that felt as though it originated in our stomach and extended outwards.

After an hour had gone by, I experienced anxiety suppression and felt as though socializing had become easier. My friend also became more talkative and reported mild muscle relaxation. They stated that the fluoro-phenibut seemed more sedating than phenibut.

At three hours in, I felt like I was peaking on the fluoro-phenibut. The dosage felt like it was on the lower end of the strong. My friend and I decided to redose 150mg at this point (6:30PM). The physical euphoria was getting very intense and I felt strong cognitive euphoria about nothing in particular other than I was high and felt really amazing. I started to think my redose might be too much, but decided to wait and see. I had a feeling similar to that which I experience on stimulants where I felt like "FUCK YEAH" at the world for no reason. The overall high felt very similar that which is experienced on phenibut, GHB, and GBL. We both felt disinhibition, but it was not as intense as benzodiazepines or alcohol.

I also began to have mild nausea and dizziness, but I figured that must be from taking so high of a dose as well as a redose. The physical euphoria was hard to ignore and was still overwhelming.

The fluoro-phenibut lasted ages and I still felt its effects when I went to bed at 2AM, eight hours after I took my redose. Next time, I will likely dose 550mg or 600mg since anymore might make me too nauseous.

Later that day, my wife dosed 500mg of fluoro-phenibut and thought it was an enjoyable experience, but stated that she would like to try 700mg next time. Keep in mind that both her and I are hardcore gabagenic users so our dosages might be too intense for most average people.

I slept for 12 hours and when I woke up, I still felt very tired and comedowny from the fluoro-phenibut. I felt sluggish and slow all day, although the 3-MeO-PCE that I took two nights ago may be contributing to this as well. My friend, who had taken the 300mg dose and a 150mg redose, also remarked that they felt comedowny, tired, and slow.

Overall, fluoro-phenibut is a huge improvement to phenibut and will definitely be something we will explore more in the future. It seems like a very good GHB or GBL replacement and is incredibly recreational.
