Phenibut Experience

[agoraphobe]

I'm trying to not get myself sick. I've developed a gabapentin addiction. I take approximately 4 grams a week spread out over 4 days. So when I take I'm taking a gram a day.

This rate is more than my prescription can provide for and I'm on pace to run out 10 days early.

I recently acquired Phenibut HCL 250 mg capsules. I already took 300 mg gabapentin in the AM. If I take 250 mg phenibut now later in the afternoon, am I doing something dangerous? I barely feel the gabapentin anymore. The point of this is to use something that will stretch my gabapentin prescription.

I'm also not sure if the source is safe but I'm not going to elaborate on that. All I'll say is they were on page 1 of Google.

Will this all get me sick, in danger etc? Thank you

I ended up taking 500 mg HCL. 250 mg then another 250 an hour later.

First thing I noticed was the nausea within 20 or so minutes. I definitely made an impact on my agoraphobia for the better. Was able to shop in Target which is hard because at baseline I don't like being far from exists.

I did not feel high or euphoric. Bummer. Sleep wasn't any better. Didn't feel sedated. I assume this has to do with my gabapentin tolerance? Using 4 days a week? Or maybe dose was too low or poor supplier quality/incorrect dose labeling. I have more to say but I have to go into work

Phenibut just sucks.

And some people have to take their phenibut doses incredibly high in order to make it work.

Honestly, I like gabapentin with no tolerance. But phenibut couldn't really come close to gabapentin. Maybe slightly but too slightly & it also made me feel nauseous.

Both phenbut & baclofen had the ability to make me feel extremely sick, usually the next day. Like nauseated hang over type sick. But gabapentin never did. I assume because gabapentin is not really a gaba agonist like phenibut & baclofen. It just causes a cascade of actions that tell your body to release gaba, rather than agonize the gaba receptors like baclofen & phenibut do. Gabapentin is a voltage-gated calcium channel blocker. It attaches to the α2δ subunits. This inhibition reduces the influx of calcium ions into neurons, which can help to suppress neuronal excitability and reduce pain. Phenibut is a weak gaba B agonist, which causes a release of gaba, along with being a calcium channel blocker. So having a gabapentin tolerance will mess the phenibut experience up a bit.

In higher doses, phenibut is also thought to act on gaba A receptors, similar to benzodiazepines.

It was so non-enjoyable to me, that I still have a bottle of phenibut capsules from like late 2018-early 2019. I became afraid to take them cause of the nausea & sick-type feeling they gave me, especially in my stomach. Almost felt like I was poisoned. If it had not been for that, I might have enjoyed them more.

reduce pain

That's the other thing. I don't have pain but gabapentin when taken in correct amount with some time in between gives me a lovely body high. I didn't get any body high from phenibut.

Phenibut almost felt like an antipsychotic mood stabilizer. It put me in a hard centered mood. Not down but not up. Just centered emotionally.

Chat GPT says this was due to me having tolerance already from gabapentin. I.e the underwhelming experience.

Again. This may all come back to sourcing too. Maybe the capsules only had 50 mg of phenibut. What do I know. Hit or miss. But previous blue light commentary made me feel like I was taking a big step up from gabapentin to phenibut in regards to recreational high. In reality it felt orders of magnitude weaker than gabapentin. Like comparing a drug to say magnesium glycinate, ashwaganda, l theanine etc

You're not going to feel anything with such low doses. Phenibut only starts being noticeably psychoactive at doses of 1000mg+. Phenibut has terrible bioavailability, like only 5%, so you have to take a lot.

But yeah, phenibut sucks. I imagine it would be useful for gabapentin withdrawal though. You aren't going to feel anything at all from 500mg. And remember, it takes like 6 hours to take effect.

 

[agoraphobe]

Lol isn't that madness?

Do you have a source for this? The literature is a bit conflicting, wikipedia states ~63% oral BA

Phenibutan—an Illegal Food Supplement With Psychotropic Effects and Health Risks - PMC

Phenibut (β-phenyl-γ-aminobutyric acid) is an analog of the neurotransmitter gamma-aminobutyric acid (GABA). Like abapentin and pregabalin, it inhibits α2-δ–subunits of voltage-dependent presynaptic calcium channels. The potential harm resulting ...

pmc.ncbi.nlm.nih.gov

This study states it has ~65% oral BA in the table comparing the gabapentinoids. Yet it causes confusion for a reader at the bottom by including a questionaire where one of the questions is if it has 20% BA (framed in such a way that makes it a statement)

Other studies seem to claim its around 65% as well. If it only had 5% oral BA that would technically be a ”good” thing since a superior ROA would make it vastly more potent. Although I cannot see it being true as IV phenibut would then be ~20x stronger than oral which from user reports it is clearly not

Apologies, I was misremembering. Its not a BA issue, it has a relatively very low rate of crossing the BBB (blood brain barrier), only a tiny fraction of any given dose reaches the brain. Which is why its dosed in grams, compared to its analog baclofen, which is dosed at 10mg.

I can't find the paper atm, ill try later when im off work.

Ripped off most$ likely. Please do not test this with huge quantities. But Gabapentin is not likely kill you.
Believe it or not you have a rather light gabapentin script. Is it Nuerontin or one of; I believe 2 other variants. We hat is it for?

Can you give me a country? Also if you are in America, does your state exercise it's right to make certain drugs schedule 5? Like Gabapentin. Also if not scheduled then good.

I think the only answer would be to ask for a serious bump. If it is really needed.
If this is about potentianting weed or another drug. Then you are just adding to the mix.

However, I suspect anxiety.

If it really is medically needed, the good news is I am unaware of gabapentin itself; causing any overdose deaths.

If you elaborate on, in general why you are on it. The daily dose sounds very small.

Also, you are a Greenlighter, but can you give me an idea of what your doctor is like.( if given from a doctor whose is your regular General Practitioner ( GP)(Internal medicine). Family doc or specialist and is this for diabetic nerve nureopathy( mis?) Is it for other extremities( aka a variation of the most common one).

Please tell this is for a specific issue and not because of a chicken shit quack coward; who is too afraid to wtite a legitimate script for pain meds.

Don't ever use the word addiction around doctors.= I certainly hope that gabapentin isn't being used for things it doesn't help. Gabapentin off label is one of the key prescriptions that many use for opiod withdrawal.

Honestly, it works well with clonidine and a Benzo. (also a bunch of OTC stuff, apparently they help, never used black seed oil, ect...)

The name leads me to wonder. Is the Gabapentin for anxiety? The reason I bring that up is your chosen, (name, handle, alias, avatar name ect..) and gabapentin is used off label as a much less dangerous and depending on the state or country not a controlled substance.

A warning. This is also firsthand. Tolerance builds fast. If you can get a dose that works; prescribed to you, don't abuse it!!!!!!!. Your tolerance will jump if you take it too much and even then.

Sorry, but if you really need it, taking alot more quickly, will only help skyrocket your tolerance. Use as directed. However, you may need more prescribed.

Along with 2 that are controlled( Gabapentin was scheduled #5 but it is a state prerogative whether or not to make schedule #5 or a simple script. I am on Gabapentin, also, but a slightly higher amount for off label use.( legal)

I would be careful about saying addiction.
If you truley are, I can't know. However, did you just not get the right dosage? Or is this something different.

Along with myself; I had a family member on it. He needed it and hated it. Some people react differently.

Things were different before the March 2025 Coup d'tate here at Bluelight. People were closer( yes this a global platform) That is another story.

Could you provide slightly more context. I do get the impression that you are a responsible sober person with anxieties.
Is this anxiety related? If it is on page one of google. Ah, I am guessing it isn't great, then again the reviews on it are always; in one way or another, a disappointment.

Do you take it 3x times a day 300mg x3 x4 days=3.6 which rounded up is about 4 grams every plus extras.

You said AM does that mean 2xtimes a day Am and Pm? 300mg x2 times a day =14 ×300mg = 4.2 grams.
Am I close.

I just am trying to figure it out. Depending on which one and it's use it could be you are under medicated.( It happens)

I know some things. Rough description of your doctor. Also, rough description of why you are on it.

 

[Jnowhere]

ok, maybe I should have read more of the posts, eh

 

[BadBoy377]

I've always enjoyed phenibut. You gotta find the right dosage though.

It can be tricky to use though. You got to respect it and invest the time in it. Dose right and you'll have a great day. Not overwhelming but just a good day. Got to consume it right too. It potentiates things too. Experiences, situations and substances too.

Like any drug it's not for everyone though.

I'm definitely not encouraging anyone to take it. It is special though.

 

[agoraphobe]

You got to respect it and invest the time in it.

Only agoraphobics realize how surprising it is to find a non bezo alleviate those symptoms. Which it did while shopping in Target. I just think I wanted to get high, yet I didn't really feel high. It was way more mental than physical for me.

I'm happy you replied because reading phenibut threads you appeared to be an expert. I will try it again. Probably on Friday. Will bump from 500 mg to 750 mg. Must stretch gabapentin out before script runs out. Phenibut will cover usual 1g gabapentin Friday.

 

[BadBoy377]

Thanks for the compliment, friend. I don't know if I'm an expert but I was an regular user for several years. I found it a positive thing. I was always wary of misusing it though.

My threshold dose at start was 1 - 1.5g and I slowly increased over the years to 3 to 4g depending on various factors. I definitely found it therapeutic in its effects. You can get high on it. I found it a kinda pseudo manic type thing. I was super productive and just happy to be engaged in my activities. Socializing was a pleasure.

Not entirely sure what you're try to achieve with it but happy to discuss in PM if that helps at all.

Definitely slow increasing of dose is the way to go with a week between.

An "Antipsychotic moood stabilizer" is a good way to describe my experience with it.

I remember the first time I took it in 2018 0r 2019. it was after a meth binge. I remember I walked up to the gas station to get something to eat. And it was turning to sunset & I think it might've been getting close to fall, so the sun had this orange glow to it. I remember standing at the gas station thinking "wow, I feel kinda comfortable/serene". But there wasn't any real mood-lift or anything. In fact I felt kinda flat, mentally.

Later that night I had terrible sleep paralysis too. And the next morning I woke up feeling I had a stomach full of toxins.

Yeah, careful what you read on here. lol Lots of misinformation unfortunately. There are people here who will tell you "kratom will get you high", yet I've never experienced anything enjoyable from kratom EVER. And everyone in my inner circle who enjoys opioids, also says they can't understand wtf people see in kratom. So it's not surprising BL made it sound like phenibut is better than gabapentin.

Phenibut is just trash. Your experience sounds very similar to mine & I wasn't even on gabapentin back when I tried it. In fact it wasn't until years later that I actually got on gabapentin for fibromyalgia & could compare it. And it was nothing like phenibut.

 

[BadBoy377]

I've never tried gabapentin. So can't compare.

I would say phenibut is very different to other gabapentinoids I've tried like pregabalin and GHB.

I've also tried lots of other medications that I would say are trash but have helped a lot of other people. Everyone's individual physiology is different and that's the most important factor.

 

[evo4ever]

I've always been interested in Phenibut, what's it like compared to Pregabalin?

 

[BadBoy377]

Pregabalin causes a mildly stimulated drunken high at high doses.

Phenibut causes relaxation but clear mindedness. Can enhance socialising and music. The afterglow can last for a day or two. Dose dependant.

 

[Innerpeace]

I’ve used phenibut since 2005 at most twice a week, many months breaks of not using it so I have experience with it

Ive sub q ed it with makes bioavailability higher and didn’t get much from it so I’d say oral dos ing is best

Op i don’t recommend phenibut in your situation with gabapentin bc it’s best used infrequently

Maybe on an off gabapentin day, if your aim to to ween off gabapentin

I used to work as security in nightclubs, bars in my younger years and would take it in a Saturday night and hangout after the shift go out and eat with the work crew and it it did seem to cause increased social relaxed feeling

The cost of phenibut has increased a lot since ten years ago, at least where I see it sold. Does baclofen have this increased social feeling like phenibut?

If so can it be taken during the day like phenibut with about the same effects?

I just discovered baclofen and have only took it for sleep. One guy said they are nothing a like

I heard they were or are bc they both work on gaba b

Btw I would not mix this with cannabis
Every time i mixed phenibut with weed it didn’t go too well and seemed to interrupt sleep for me

phenibut for me was best at 1-1.5 grams . Never pushed it past 1.5 as didn’t think it was needed. Definitely was felt into the next day if I took it for sleep

 

[agoraphobe]

There are people here who will tell you "kratom will get you high", yet I've never experienced anything enjoyable from kratom EVER

I disagree with this from experience personally. I get wrecked from Kratom and it's lovely. But I agree with the other stuff you said.

 

[PtahTek]

Depending on surroundings
Phenibut should be scheduled about 6 hrs before popping on the scene at a social event. Below 500mg and I get great sleep but not so much "high". Alone I don't feel a lot but know something is deferent.
Anyway when I did it it was 1.5g a day in early morning before work. Ever three days I took it for a couple years. It was magic. No matter what drama was going on in a busy/demanding kitchen it was nothing; everything seemed to be no problem and everyone was back to a team stat... magic imo/e. Ymmv
Be careful, yeah?
Be easy and safe
Peace
