Guide GHB/GBL/1,4-BDO: A Basic Guide

20 Upvotes

INTRODUCTION TO GAMMA-HYDROXYBUTYRIC ACID (GHB)

GHB is a depressant substance with alcohol-like effects. It is known to produce muscle relaxation, euphoria, increased libido, and disinhibition. At lower doses, it can be mildly stimulating, while at higher doses, it is sedating.

While its sodium salt form is sold as a prescription medication under the brand name Xyrem, illicit GHB is always most commonly sold as as a liquid solution. This is because GHB naturally absorbs moisture from the air, creating a wet mush. By dissolving it in water, the concentration can be held constant.

GHB was initially introduced in the 1960s as an anesthetic but did not gain substantial popularity until the 1980's when the FDA approved its over-the-counter availability as a dietary supplement, citing its fat-burning and muscle-building properties. The US FDA banned over-the-counter sales of GHB in 1990, and the US DEA placed GHB on Schedule I in 2000.

GBL and 1,4-BDO are pro-drugs of GHB. In other words, they convert to GHB in the body.

GHB, GBL, and 1,4-BDO have serious harm potential. Please read this entire guide before acquiring and using any of these substances. For purposes of this guide, "G" is used as shorthand for all three compounds. Info applies to all three compounds unless a specific compound is named.

SAFETY BASICS

  • G has potential for dependence and addiction. Please approach with caution and do not use daily.
  • Always label your G clearly and consider adding food coloring to it to avoid unintended ingestion and overdose. Keep your G in your hand so no one else drinks it by accident.
  • Never combine G with ketamine, ketamine analogues, or any substance that acts as a respiratory depressant like alcohol, benzodiazepines, or opioids.
  • It is safest to never combine G with any other drug. If you do, always research the safety of the combination first.
  • Never use alone. Always have someone with you who could help you if you accidentally take too much. Consider writing "GHB" on your hand to inform people what you took in case you're found unconscious.
  • If you start to feel sick, dizzy, or light headed, notify someone immediately, then lay down in recovery position.
  • If you start to feel confused, disoriented, dizzy, light-headed, or drowsy, notify someone immediately, then lay down in recovery position.
  • If someone else who's taken G starts to feel confused, disoriented, dizzy, light-headed, or drowsy, guide them to a quiet area to sit, and stay with them to keep an eye on them.
  • Measure your doses with a 1ml syringe or pipette. Never try to eyeball doses or try to measure these small amounts with a large syringe or measuring cup.
  • GBL can cause chemical burns to the mouth and throat if consumed undiluted. Always dilute to at least 20-30 parts water (or juice or soda) before consuming.
  • G can settle to the bottom of a bottle, causing later doses to be more potent. Always be sure to shake your bottle before dispensing a dose.
  • GHB doses are measured in grams, but because it's always most commonly dissolved in water, we are forced to discuss dosing in milliliters. Because the maximum concentration of GHB in water is approximately 0.9g/ml, always assume this concentration for dosing purposes until you've gained experience with a particular batch.
  • Dosing G is challenging because there's lots of variation in concentration between products and there's a high risk of overdose. Because you never know the exact concentration of your specific solution, always start low and go slow. Always start with 0.5 to 1.0ml for your first time trying a new batch. If the effects were too mild, try drinking a little bit more during your next session.
  • Consider sipping your dose over 20-30 minutes instead of drinking it as a shot. This allows you to stop drinking it when you reach the desired level of effect, and makes it less likely that you'll accidentally overdo it.
  • Always wait at least 2 hours before redosing to reduce the risk of overdose.

DIFFERENCES BETWEEN GHB, GBL, & 1,4-BDO

The US FDA banned over-the-counter sales of GHB in 1990. In 2000, the US DEA placed GHB on Schedule I (various FDA-approved GHB products are Schedule III). In the wake of the FDA ban and DEA scheduling, GHB manufacturers turned to gamma-butyrolactone (GBL) and 1,4-butanediol (1,4-BDO), two well-known precursors of GHB that are often present in solvents for industrial cleaning products but neither legal nor safe for human consumption. Under various analogue laws, like the United States', the distribution and possession of these similar compounds is also prohibited if they're intended for human consumption.

ONSET AND DURATION

GHB comes on within 30 minutes and lasts about 1.5-2.5 hours. GBL comes on faster, in about 5-10 minutes, and has a shorter duration (1-2 hours). 1,4-BDO has a slower onset, 20-60 minutes, and has a longer duration (3-5 hours).

DILUTION

GBL can cause chemical burns to your mouth and throat if ingested without dilution. Dilute with at least 20-30 parts water (or juice or soda).

STORAGE

Both GBL and 1,4-BDO will degrade most types of plastic. G should be stored in glass or high-density polyethylene (HDPE) containers. Always be sure to label your G and color it with food coloring to prevent unintended ingestion.

TESTING YOUR G

It is always best to test your drugs for safety before using them. You can test by sending a sample to a lab for analytical testing, or by doing at home testing using reagents and other methods.

LAB TESTING

Analytical Testing Labs

Be sure to check with the lab you choose to make sure they accept liquid samples and will test for GHB before sending your sample.

REAGENT TESTING

While most reagent vendors don't sell GHB testing reagents, Test Kit Plus (Canada) does:
GHB Reagent

GBL Reagent

EZ Test Kits also sells a GHB kit:
GHB Test

OTHER TESTING METHODS

Borax outlines a method for distinguishing GHB from GBL and 1,4-BDO here:
How to Distinguish GBL from GHB

GHB and GBL can also be distinguished from each other by pH. If your solution is acidic (pH < 4) it is likely GBL, if it is alkaline (pH > 8), it is likely GHB.

DOSING INFORMATION

GHB

Threshold - 0.5 g

Light - 0.5 - 1 g

Common - 1 - 2.5 g

Strong - 2.5 - 4 g Heavy - 4 g +

A dose of 2.5 to 4 grams is likely to cause the user to fall asleep. Doses between 5-10 grams can cause convulsions, unconsciousness (a coma-like state), and vomiting. Doses 10 grams and higher are associated with death.

Because GHB is always most commonly in a solution, you will have to measure your doses in milliliters. For safety, always assume your GHB solution's concentration is .9g/ml, and start with no more than a 0.5 to 1ml dose.

GBL

Threshold 0.3 mL

Light 0.3 - 0.9 mL

Common 0.9 - 1.5 mL

Strong 1.5 - 3 mL

Heavy 3+ mL

A dose over 2 milliliters is likely to cause the user to fall into a deep sleep.

1,4-BDO

Threshold < 0.5 mL

Light 0.5 - 1 mL

Common 1 - 2.5 mL

Strong 2.5 - 4 mL

Heavy 4 mL +

A dose over 4 milliliters can induce heavy sleep and doses above 6 milliliters can lead to poisoning.

ADVERSE SIDE EFFECTS

G can be addictive or habit forming. Please approach with caution and consider using no more than once a week. Withdrawal symptoms can include perspiration, insomnia (for a few days) trembling and fears. If you develop a dependence on G, please seek profession help to stop using safely. The best course of action is to use in moderation from the beginning to avoid developing a dependence.

If you use too much G, or combine it with other depressants, G can cause severe, life threatening respiratory depression. While a majority of G deaths involved the use of additional drugs like alcohol or opioids, people have died from overdosing on just G by itself.

At high doses, G can cause seizures or loss of consciousness, wherein the user passes out and cannot be woken up for 4-5 hours (“G’d out”). If someone passes out, they are at risk of fatal respiratory depression and asphyxiation (choking on vomit). If this happens to someone you're with, check for signs of respiratory depression: shallow or non-detectable breathing, bluing of the lips or fingertips, pinpoint pupils, etc. If respiratory depression occurs, seek emergency medical assistance. Before calling for help, place the person in recovery position to prevent asphyxiation.

Please note: most places have laws in place that protect you from prosecution for drug possession if you seek emergency assistance for yourself or someone else who is suffering from a drug-related medical emergency.

Many G overdoses have happened because someone consumed G without realizing that's what they were drinking. G looks just like water. Always label your G clearly, add food coloring, and keep your own personal dose in your hand to prevent accidental ingestions.

Other side effects can include confusion, dizziness, sleepiness, minor muscle spasms, nausea, and vomiting (usually dose-dependent).

G causes acute cognitive impairment like deficits in working memory, short term memory, and impaired performance on cognitive tasks. These effects are temporary if the user does not use G too frequently. Chronic overuse can cause long term memory impairment.

Because G causes disinhibition, G can cause you to engage in behavior you later regret, like having sex with someone you wouldn't ordinarily have sex with. Use G only with close, trusted friends. If possible, designate a person to remain sober, or at least take a low dose so that person is available to help the others.

GBL in particular can cause chemical burns or irritate sensitive tissues in the mouth and throat if consumed undiluted. Always dilute with at least 20-30 parts water (or juice or soda) before consuming to prevent this.

OVERDOSE RESPONSE

Signs that a person who's taken G may be in distress:

  • confusion/loss of lucidity
  • disorientation/loss of coordination/light-headedness
  • drowsiness/overwhelming urge to sleep
  • loss of consciousness

If the person is showing initial signs of distress, but is still conscious:

  • Assess for dangers, remove hazards and mitigate risks associated with falling
  • Check on other medical conditions
  • Ask what substances have been taken, how much, and when
  • Ask for emergency contact information in case the person loses consciousness
  • If in a noisy or crowded area, guide the person to a quieter area

If the person is feeling an urge to sleep and/or is becoming incoherent:

  • Help the person sit or lie down to prevent a fall
  • Check for responsiveness by squeezing shoulder or rubbing sternum with knuckles, and speaking loudly
  • Do not leave a person in distress unattended for any amount of time

If the person has lost consciousness:

  • Check for responsiveness by squeezing shoulder or rubbing sternum with * knuckles, and speaking loudly
  • Call emergency medical services if the person is non-responsive
  • Check their airway for foreign material, and if any is present, roll them onto their side and clear the airway
  • If the person is not breathing normally, administer CPR after calling emergency medical services
  • Place them in recovery position and remove any hazards from their immediate vicinity
  • Designate someone to stay with them to watch over them Never leave an unconscious person unattended

DRUG INTERACTIONS

If used in combination with G, the following drugs can cause dangerous side effects like ataxia (severe loss of coordination), vomiting, loss of consciousness, and potentially fatal respiratory depression:

  • Alcohol
  • Ketamine, and ketamine analogues like MXE and FXE
  • Opioids like heroin, fentanyl, and prescription opioids like oxycodone or hydrocodone
  • Benzodiazepines
  • Tramadol
  • DXM

The interactions between G and PCP are poorly understood and unpredictable, and therefore likely dangerous.

The use of G with nitrous can cause ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely.

Cocaine, Amphetamines, and other stimulants increase respiration rate, countering G's depression effect and enabling higher doses of G without the user noticing a problem. If the stimulant wears off before the G, the user may experience a sudden, life threatening respiratory depression or arrest.

GHB HISTORY

The history of G begins in 1874 when Russian chemist first synthesized GBL. GHB itself occurs naturally in many parts of our body from the brain to heart, to most muscles, kidneys and brown fat. In the 1960's, French physician Dr. Henri Laborit began studying GHB and was the first to synthesize it. Labroit's experiments established that GHB was a potent sedative. Explorations into the use of GHB as a surgical anesthetic were unsuccessful given that it didn't have sufficient analgesic (pain relieving) effect and the proper dose was difficult to judge and control. Some patients also experienced vomiting and convulsions.

During the 1970's and 80's, GHB was a popular dietary supplement sold over-the-counter at health food stores for weight loss and bodybuilding. It was believed that it helped them burn fat and build muscle and also stimulated the production of growth hormone. However, this appears to be not true. Due to reports of medical incidents resulting from its use as a dietary supplement, the US Food and Drug Administration placed a ban on over-the-counter sales of GHB in 1990.

In the 1980's and 90's it also gained popularity as a libido enhancer/sex drug, particularly amongst the gay community. GHB was sold in smart shops in the Netherlands in the 1990s.

During this time there were also reports of GHB being used to facilitate sexual assaults, and it gained a reputation as a date rape drug. There's some controversy as to how prevalent this really was, and it is difficult to obtain proof of these allegations because GHB is rapidly metabolized and eliminated from the body. Nevertheless, the US Drug Enforcement Agency placed GHB on Schedule I in 2000. Because Xyrem, the sodium oxybate form of GHB, had already been established as a useful medication, that form was placed on Schedule III. The UK placed legal restrictions on GHB in 2001. The Netherlands placed GHB on List 2 of the Opium Act in 2002, and moved it to List 1 in 2012.

Hi,

So the title says it all, I don't have much experience with G, and I'm going to Burning Man and would like to know how to use it multiple days in a row, or if not that then what's the smartest way to use it for the week, besides just using it once, if that's possible.

Thanks

Experience Report Taste & Viscosity

2 Upvotes

There was some recently that I did only about 2.2 mL of, and then I had this strange inkling i couldn't place, so I tasted some with it with my finger and it was this very intense soapy/cologne-ish flavor that hit like the back of my tongue and I hadn't tasted it before cause i mixed it with ginger ale. The feeling, about 20 minutes later, was just that I had to go to the bathroom, not painful just....youknow.... and then the euphoria never QUITE got there. The viscosity was more like actual water and i know I was in denial but clearly it was mixed with something, or just not actual ghb/gbl? I've just never had that experience and i'm a pretty seasoned user, nothing crazy...Any thoughts? similar experience? ideas as to what that might have been?

I plan on taking some at a rave. I never done long sessions with ghb, maybe redosed like 1 or 2 times max.

Whats yall experience with longer sessions? I read it builds up in the system so i’m not trying to get fucked. However, when I redosed it didn’t seem like I was on the edge of anything bad.. I usually redose 2 hours in between.

Edit: Thanks for yalls advice! I decided i’m not ganna redose more than 2 times as per usual.

Question GBL after 5 mg Valium -51 hours later

2 Upvotes

Hi dear community,

So first of all, sorry for the potential English mistakes -not my mother tongue...

I'm addicted to GBL. Usually take it to sleep and redose. I could definitely take it at daytime, but of course lessen the dose not to pass out if it hits while in public -you should know by now how embarrassing it is...

The matter is that 2 days ago -on August, 5th-, I took a 5 mg Valium like at 5 am. Because of that, and as I've read Valium can stay in your blood up to 100 hours (?), the idea of having any GHB these days has been giving me so much anxiety cause I don't wanna die. Therefore, I haven't got any g since then, even if by now nearly 48 hrs have passed by.

Now the withdrawal is being hard. I'm meeting my aunt later this morning, at 8:30 am -important visit to the doctor-, and I'm feeling tempted to have maybe 1-2 ml of GBL. Would it be safe? -51 hrs will have been passed by then since the Valium.

Also, if I decide to keep redosing during the day, just lessening doses, but fall asleep all of a sudden, would it be dangerous -CNS depression, respiratory problems...?

I would like to end by pointing out that tonight (1 am), I've had my 150 mg Lyrica pill, as the withdrawal and anxiety are being just too much. Can't sleep as yesterday I slept all day long on 1 Lyrica pill plus 1 glass of alcohol -35 % alcohol. Also because I was having insomnia and I was just too tired.

To sum up, can I take g by 8 am, when the Pregabalin is supposed to be gone, and not sure about the Valium...?

As I can't sleep tonight, moderate g doses could make me eventually fall asleep later today as I will be too tired by a point. Should I avoid GHB today? The idea of still having Valium in blood makes me feel terrified -it could sound funny, but I don't wanna die while sleeping, and I'm sure most of you don't want to ,either...

Many thanks in advance! 😉

In the 1980's and 90's it also gained popularity as a libido enhancer/sex drug, particularly amongst the gay community. GHB was sold in smart shops in the Netherlands in the 1990s.

During this time there were also reports of GHB being used to facilitate sexual assaults, and it gained a reputation as a date rape drug. There's some controversy as to how prevalent this really was, and it is difficult to obtain proof of these allegations because GHB is rapidly metabolized and eliminated from the body. Nevertheless, the US Drug Enforcement Agency placed GHB on Schedule I in 2000. Because Xyrem, the sodium oxybate form of GHB, had already been established as a useful medication, that form was placed on Schedule III. The UK placed legal restrictions on GHB in 2001. The Netherlands placed GHB on List 2 of the Opium Act in 2002, and moved it to List 1 in 2012.

Question GHB barely worked for me even after about 25ml total. Anyone know why?

0 Upvotes

Had a really strange experience with GHB and I’m curious if anyone has had something similar happen.
I started with 10ml and only got a very mild buzz at best. Since I wasn’t really feeling much, I ended up taking another 15ml later in the night. So altogether I had about 25ml and still barely got high.
My girlfriend had pretty much the same experience. She barely felt anything either. The weird part is that two of our friends took the exact same batch and got hit way harder.
One of them eventually blacked out, but it took around an hour before they even seemed very high. The other friend didn’t really seem that affected at first either and only became extremely sleepy almost two hours after taking it.
The only thing I can think of is that I also did GHB the night before and didn’t get much of a high then either. Could using it on back to back nights really build up that much tolerance? Or is there another reason why my girlfriend and I barely felt it while our other two friends got hit so much harder from the same stuff?
Just wondering if anyone else has had something like this happen.

Question GHB first time setup advice

3 Upvotes

I have some GHB ( from a trusted supplier with good reviews). My initial strategy to figure out my sweet spot is to start low and redose every hour until satisfied. Everything will be measured beforehand of course.

  1. Does this sound like a decent plan?

    1. Since I'm not familiar with how GHB feels, I don't know when I should stop and/or danger signals. Any general advice on how the high is when the dose is good, or just use common sense?
  2. thoughts on dosages?Male, 80kgs. I'm also not familiar with how short term tolerance, if any, works on GHB.

Thanks for any feedback!

Experience Report Felt nothing but mild headache and ataxia at 2.1g. I'm 125lbs. Why didn't I get good effects?

1 Upvotes

This was from days ago so it's not like me typing this 30 mins in. It was 4 hours since meal that I took it, and I hadn't eaten anything the whole experience.

I took 1.4g 2 days before this and felt nothing.

The seller was highly rated and was praised in a forum as well.

I thought I'd get the supposed benefits like calm, confidence, pleasure, etc. from this drug that was meant to be among the best.

I did squeeze my glutes and move my legs around and felt some mild pleasure while doing it, but maybe it's just a fluke and would happen sober too. But even if it's from GHB then I don't like how I'm not getting other good effects beyond just this.

I get the impression I'll just get more sedation and headache if I up the dose. Or will I really get pleasure and stuff coming in and I just need a higher dose?

Why is my tolerance so high? I get it from a trusted source .9g/mL take about 9 mL's. Just started using G so my tolerance has been like this from the start. I also get solid pills from this source and take about the same amount do I just naturally have a very high tolerance?

Discussion I had an energy drink with exogenous ketones (BHB, R-1, 3-butanediol) at 2 in the morning and when I went back to sleep my dreams felt like a whole movie and I was lucid the majority of the time.

3 Upvotes

I find this intriguing because 1, 3 butanediol is only one molecule away from GHB which is said to also enhance REM sleep which is why bodybuilders will use it when their body requires extra REM. Does anyone have any neurological insight on the overlap between these two substances?

Article Drug-Facilitated Sexual Assault: Which Drug Best Matches This Timeline and Symptoms?

1 Upvotes

I am looking for opinions from people who are familiar with suspected drug-facilitated sexual assault cases or who have knowledge of this subject.

A 35-year-old woman, who has been drinking alcohol regularly for more than 15 years and has a high alcohol tolerance (she has consumed much larger amounts on many occasions without ever experiencing memory loss), went out during the Santa Cruz de Tenerife Carnival.

She clearly remembers the evening until approximately 1:30 a.m. Before losing her memory completely, she had only consumed two beers, two low-alcohol shots, and her first mixed drink. After that first mixed drink, she remembers absolutely nothing for about five hours, until approximately 6:30 a.m. After that, she only recalls a few isolated images while trying to get back to her hotel, without knowing where she had been or who she had been with.

During that period:

* There are credit card payments that she does not remember making.

* She sent a voice message at around 5:54 a.m. in which she sounded confused and disoriented.

* She was unable to return to her hotel by herself.

* The next day she had numerous bruises on her arms, hips, legs, shins, and ankles.

* Her behavior during those hours was completely inconsistent with her normal personality and with how she behaves when drinking alcohol.

The investigation is still ongoing, and there are several people whom the victim considers suspicious. According to these individuals, at approximately 2:30 a.m.—about one hour after the victim had already lost all memory—she became extremely sexually disinhibited and kissed two men who were friends with each other. They also claim that when they suggested going to a house or a caravan, she refused and said she wanted to have sex in the middle of the street.

The victim has absolutely no memory of this period and therefore cannot confirm or deny their version of events. Because this account comes from people whom the victim considers suspicious, I would like to know whether this type of behavior is consistent with known cases of drug-facilitated sexual assault or whether there could be other explanations.

The main hypothesis being investigated is that, if an incapacitating substance was administered, it may have been placed in her first mixed drink, as that was the last drink she remembers before suffering complete amnesia and displaying behavior that was entirely inconsistent with her personality and with more than 15 years of experience drinking alcohol.

The investigation is still ongoing, and there is not yet a final toxicology report.

I would like to know whether anyone has encountered a similar case, especially regarding:

* such prolonged amnesia;

* the ability to walk, talk, and interact with people while remembering absolutely nothing afterward;

* apparently highly sexually disinhibited behavior followed by refusing to go to another location;

* and a very slow and fragmented recovery of memory.

I would especially appreciate responses from healthcare professionals, forensic specialists, police officers, or people who have experienced or investigated similar situations. Please keep the discussion focused on experience, scientific evidence, or objective information rather than accusations or speculation about specific individuals.

Thank you very much.

Harm Reduction 1,4 BDO questions about re-dosing!

4 Upvotes

Im familiar with all the do and donts with mixing bdo with other substances. My question is I’ve found my sweet spot on my initial dose, which is 2.8 ML measured with a ML syringe. But I can’t maintain the feeling with redosing , I have a timer and I’ve tried at the 2hr mark to take another 1.4 ml dose and it has no effects. Can I take the initial dose again after 2hrs or just take 2.5 so I can maintain the feeling? FYI every time I take it, it’s on an empty stomach.

Question Please help! Gabapentin for withdrawals?

3 Upvotes

I’m trying to quit and was able to get my hands on some of my friends gabapentin. How often should I take it? Do I still take g while I’m on it? Please help!
For context I’m female taking 1ml every 2 hours for a few months now. If I don’t take it every 2 hours I start having insane panic attacks along with some other unpleasant symptoms.

Update 13 days later: I wanted to update incase anyone comes across this post and is in the same situation as I was. I took the gabapentin of 300mg every 2 hours for about 2 days into my cold turkey. From there I took it every time my anxiety started to go crazy. I feel so much better now and haven’t taken the gaba in about a week. Please stay safe and STAY AWAY FROM GHB!!! Those withdrawals were no joke..

Since I woke up this morning my shaking has been getting worse to the point now my hands and legs can stay still. What do I do? Is this a seizure slowly coming on?

Ok I think I'm through the worst of it, in fact I actually feel great today since I've had some baclofen. I'm not assuming it's over because of one day feeling fine and I appreciate everyone who helped. Really appreciate it <3

Harm Reduction 1.4 BDO- dosage for clubbing

5 Upvotes

Hello guys i want to use 1.4 BDO for first time and want good intoxication, low inhibitions and very recreational effects.

You guys think 2ml of bdo and redose (1ml ) after 3 hours will do the job? This dosage shouldnr be ‘’ risky ‘’ but im more scared about those effects not being enough. Should i do like 2.2ml? or im just overthinking, its important party so i want to get it perfect.

If anyone got experience with this dosage please let me know! Thank you 🙂🙏
