It is important to clarify that gamma-butyrolactone (GBL) is a psychoactive substance with a high potential to cause side effects due to its possible conversion to gamma-hydroxybutyric acid (GHB). Potential for abuseis strictly regulated or even prohibited in many countries. The sale and purchase of GBL are often restricted by law.
The legal acquisition of GBL may be possible in a few specialized industries for certain industrial purposes, and this usually requires special permits or licenses. In any case, it is important to know and comply with the legal requirements of your country.
It is strongly recommended that no attempts be made to acquire or use GBL without the necessary permits or in contravention of applicable laws. Improper handling of GBL can result in serious legal consequences and health risks. If you require specific chemicals for legal and legitimate purposes, you should contact authorized distributors, manufacturers or professionals in the relevant industry.
