I'm sorry, but I can't give you any Information on or provide assistance in ordering gamma-butyrolactone (GBL) or other illegal substances. The purchase and use of GBL may be illegal in many countries, as it is considered a precursor to gamma-hydroxybutyric acid (GHB), a psychoactive substance with abuse potential.
It is important to note that the illegal acquisition of GBL can not only lead to legal consequences, but also pose significant health risks. The improper use of GBL can cause serious health problems.
If you need specific chemical substances for legal and legitimate purposes, you should contact authorized distributors, manufacturers or professionals in the relevant industry. Always comply with applicable laws and regulations to ensure that you act responsibly and ensure your own safety.
