What is GBL used for?


Gamma butyrolactone (GBL) is a substance found in nail paint and cleaning supplies. GBL is changed inside the body into the date-rape medication gamma-hydroxybutyrate (GHB).

The body’s conversion of GBL to GHB has the ability to inhibit some nervous system operations.

People take GBL as a party drug, for athletic performance, for depression, and other reasons despite major safety concerns, but there isn’t any solid scientific data to back these claims. 

GBL is banned in the US since it is listed as a Schedule I restricted substance. GBL should not be confused with 1,4-Butanediol or gamma-hydroxybutyrate (GHB). Although they are not the same, these substances are related.

What is GBl used for? or What are the common uses of gbl?

Butyrolactone is mostly used as a building block for other chemicals.

Methylamine and ammonia are the catalysts for the production of NMP and pyrrolidone, respectively.

It is also used as a solvent in some lotions and polymers.

Butyrolactone is used as the organic solvent in electrolytic capacitors because to its wide liquid range, chemical stability, and high dielectric constant. It is frequently used with ethylene glycol in a low ratio—”9:1″ is a typical ratio—to modify internal resistance. 

It has been used as a solvent in several scientific research, including the production of methylammonium lead halide.

A common industrial chemical solvent and intermediary is gamma-butyrolactone.

prevalent in adhesives, paint removers, cleansers, and nail polish removers.

There are hundreds of thousands of metric tons of GBL manufactured worldwide.

Unlawful uses

Due to its euphoric and sedative effects, GBL is misused.

The most popular recreational oral dose of 1 mL for GBL is self-administered most of the time.

GBL has a quicker start and a longer duration of action than GHB.

What industrial use does Gbl serve?

A colorless, hygroscopic liquid with a slight characteristic odor is known as -butyrolactone (GBL). The most fundamental 4-carbon lactone is it.

Mostly, it is used as a chemical bridge for the manufacture of other chemicals like methyl-2-pyrrolidone.

The industrial application of gamma-butyrolactone (GBL) is extensive. It is a solvent that is frequently found in circuit board cleaners, nail polish removers, paint strippers, and nail polish removers.

Additionally, it serves as an intermediary in various pharmaceuticals as well as industrial chemistry processes like making pyrrolidones.

Despite serious safety concerns and the fact that it is illegal, some people use gamma butyrolactone to enhance their enjoyment, sleep, and sexual performance.

Additionally, they utilize it to relieve stress and despair, lengthen life, encourage rational thought, unwind, and release growth hormone.

GBL is also used to develop muscles and burn fat. Some people use it for leisure activities.

More applications for GBl Gamma-Butyrolactone in industry

The publisher predicted that the global market for gamma-butyrolactone will grow quickly within the predicted time frame.

The general use of gamma-butyrolactone is one factor that drives the global market for the substance.

in the agrochemical and electrical sectors.

Within the agrochemical sector:

GBL is used as a plant growth regulator and as a parent chemical in the manufacture of herbicides.

Because of its high boiling point and low freezing point, it is a superior raw material for the electrical sector.

As a result, it is used as a solvent and in batteries. Additionally, its application in dyeing and

The pharmaceutical sector is probably going to expand.

However, the accessibility of substitutes in almost every sector and the abusing usage of GBL as a narcotic,

has compelled all nations to regulate their market flow.

The global market for gamma-butyrolactone GBL may therefore experience restraint during the forecast period.

The majority of gamma-butyrolactone production takes place in liquid form, and it is also used to make herbicides, capacitors, circuit board cleaners for electronics, paint strippers, and nail polish removers.

Additionally, it is a solvent for polyacrylonitrile, polystyrene, and cellulose acetate. Pharmaceutical uses for gamma-butyrolactone include promoting relaxation, increasing mental clarity, enhancing sexual performance, reducing fat, and enhancing sleep.

But because the substance can be abused, practically all of the world’s countries have forbidden or severely restricted its medical applications.

The agricultural sector:

It currently consumes the most gamma-butyrolactone and is expected to continue doing so for some time.

By 2026, the World Health Organization (WHO) predicts that there will be more than 8.2 billion people on the planet, greatly increasing the world’s need for food.

Gamma butyrolactone demand increased in 2018 as herbicide use surpassed 1.2 million tons.

Gamma-butyrolactone has a bright future because the US has more than one-third of the world’s market for herbicides.

As the world’s population rises, so does humanity’s reliance on technology, making it challenging for any industry to function without computers and other electronic equipment.

The global gamma-butyrolactone (GBL) market has grown as a result of the rising demand for computers and other electronic gadgets that rely on tiny capacitors.


The market for gamma-butyrolactone is being driven by the rising use of batteries and capacitors in the automotive industry, as well as the switch away from petroleum and toward batteries.

Globally, tens of thousands of metric tons of gamma-butyrolactone are produced and traded.

Approximately 185 000 metric tons of gamma-butyrolactone are produced in the US alone. The polar solvent gamma-butyrolactone is frequently used with ionic substrates.

It is incredibly beneficial for the chemical industry and is what drives the demand for GBL because it performs as an acid donor in aqueous settings at high temperatures.

Tetrahydrofuran (THF), the compound’s major derivative, is created using about half of all gamma-butyrolactone manufactured globally.

Surface coating, film casting, printing inks, and adhesives all respond well to TFH as a solvent.

In addition to being used to create graphic films, gamma-butyrolactone can also be used as a lithography developer by quickly removing and dissolving partially polymerized images.

Uncured UV-damaged coating (positive picture) or photochemically active polymer (negative image) that has not been subjected to UV radiation.

Gamma-butyrolactone can therefore be used as a dispersion and a finishing agent in photography.

GBL’s medical applications,


GBL is quickly converted to GHB by the body’s natural processes. GBL thus has a comparable

Pharmacological effects of GHB exist. Gamma-aminobutyric acid (GABA) is a neurotransmitter that is present in the central nervous system in very small concentrations, and GHB is a metabolite of GABA.

Scientific data suggests that gamma-hydroxybutyrate may function as a neurotransmitter or neuromodulator in the brain.

Barbiturates and methaqualone-like dose-dependent depressive effects are present. Low doses of GBL/GHB produce nausea, sleepiness, and visual distortion.


Paraoxonase (lactonase) enzymes found in the blood convert GBL into GHB very quickly.Animals lacking these enzymes are not affected by GBL.

GBL is absorbed faster than GHB because it has a higher bioavailability and is more lipophilic (fat-soluble).

GBL tends to be slightly more potent and act more quickly than GHB as a result of these pharmacokinetic changes, although 1,4-butanediol has the opposite effect.

A similar chemical (1,4-B) has a tendency to be slightly less effective and to act more slowly than GHB.

GBL was promoted as a nutritional supplement after GHB was scheduled under the trade names Revivarant and Renewtrient until they were forbidden by the FDA because to its capacity to function as a prodrug of GHB and increase GH secretion related to sleep.

drug use for amusement                                        

GBL’s use for recreational purposes is primarily owing to the fact that it is a prodrug of GHB. The effects of a GBL overdose can include irrational behavior, severe illness, unconsciousness, or even death.

To get past GHB restriction laws, home synthesis kits for turning GBL and/or 1,4-B into GHB were developed.

FDA alert regarding GHB and associated prodrugs, such as GBL GBL has an odd flavor and odor that has been compared to false melon, burnt plastic, and stale water. This is considerably different from GHB, which is supposed to taste markedly “salty”.

Due to how simple it is to make GBL using readily available precursors and minimal chemistry understanding, GBL has become very popular among young people in French nightclubs.


When taken orally, GBL can irritate the stomach and esophagus. GBL can cause nausea and other related problems when taken orally, probably more so than GHB.

GHB exhibits biphasic effects, with euphoric ones at low doses (thus the name “liquid ecstasy”) and sleepy ones at higher ones. Because of this sedation, it’s possible to become unconscious.

When used with alcohol, there is a significant risk of death due to the increased sedation and risk of vomiting. The two medications shouldn’t be taken together as a result, according to many harm reduction organizations.

It has been reported in the news that GBL-related deaths usually occur in conjunction with alcohol or other depressants.

Gamma-Butyrolactone is a common substance used in date rape.

Utilization and addiction

GHB or GBL do not appear to significantly increase physical dependence in the majority of users, even when used often over an extended period of time and in modest doses.

For a large majority of people, quitting drugs or temporarily abstaining from their use is relatively easy to do. However, when use is excessive and dosages are regular, physical and psychological dependence may develop.

It is crucial to consider the patient’s age, comorbidities, and the pharmacological routes of the GBL when controlling GBL dependence.

GHB and GBL users can follow a “24/7” dose schedule.

In this case, the user has developed a tolerance to the drug’s effects and has increased dosage and dosing frequency solely to prevent withdrawal symptoms.

Depending on how much and how long a user has used GHB or GBL, withdrawal symptoms may occur when they stop using the drug.

Light to moderate users typically report sleeplessness and sleep-related concerns, despite the fact that excessive, continuous use can cause severe withdrawal symptoms that resemble Benzodiazepine withdrawal syndrome (BWS).


Since the normal form of NaGHB is 1.65 g per milliliter of pure GBL, doses are calculated in the range of one milliliter and can be taken all at once or spread out over the course of a night.

GHB/GBL overdose

GBL/GHB overdose can cause:

  • unconsciousness
  • seizures
  • reduced heart rate
  • severe respiratory depression
  • decreased body temperature
  • vomiting
  • nausea
  • coma
  • or death at large doses.

GBL/GHB consumption over time can lead to addiction.

Chronic GBL/GHB misuse results in a withdrawal state defined by;

  • insomnia
  • anxiety
  • tremors
  • significant autonomic activation (i.e., elevated heart rate and blood pressure), and sometimes psychotic thoughts.

population of users

Due to its euphoric effects, GBL is sometimes used as a GHB substitute. GBL/GHB is abused by teenagers and young adults as an alcohol alternative, at all-night events and “raves,” and to improve their sex.

Gamma-hydroxybutyrate (ghb) is also known as “liquid ecstasy,” “Georgia home boy,” “grievous bodily harm,” “salty water,” “somatomax,” “easy lay,” “cherry menth,” and many more deceptive names in the gym and on the street.1 The body converts the ingredients in Revivarant, Revitalizer, Blue Nitro, and Weight Belt Cleaner into GHB.

Bodybuilders claim that GHB improves their performances by speeding the production of growth hormone, encouraging restful sleep, and the breakdown of fats

Others take GHB to:
  • suppress appetite
  • promote sleep
  • or elicit euphoria.

Due to its rumored aphrodisiac and disinhibitory properties, GHB is well known for being a component of “date rape” drugs and for being taken at rave parties.

As an example of GHB’s other lethal side, a growing number of partygoers and athletes have died or experienced severe adverse effects from it and related substances.

Gamma-butyrolactone (GBL), which the body swiftly converts to GHB, was taken by NBA basketball player Tom Gugliotta of the Phoenix Suns in December 1999.

Nearly died from respiratory failure.

Those who are fortunate enough to end up in emergency departments, like Gugliotta, typically recover quickly and completely, creating the appearance to uneducated observers that medical attention is not necessary if someone passes out after using GHB.

Due to the serious consequences of casual GHB usage and the importance of rapidly responding to its adverse effects, clinicians should be aware of this dangerous supplement.
