1,4-BD (1,4-butanediol) and GBL (gamma-butyrolactone) are chemicals that are most similar and closely related to GHB. They are often known as ‘precursors’ to GHB because they convert to GHB in the body. They are industrially used as a paint stripper or solvents.
Both GBL and 1,4 BD are often sold as GHB, and because they convert to GHB in the body, can have similar effects. Both GBL and 1,4-BD have a stronger chemical taste than GHB. 1,4-BD has a melting point of 20.1 degrees, which means it will thicken when put in the fridge.
