POWDER FOR GAMMA-BUTYROLACTONE
Gamma-Butyrolactone Powder, also known as γ-butyrolactone or GBL, is a water-soluble, hygroscopic substance with a faint, distinctive smell.
In addition to being employed as an aroma chemical, paint stripper, stain remover, and solvent in certain wet aluminum electrolytic capacitors, GHB is a widely used reagent and solvent in chemistry.
Powdered gamma-butyrolactone, also known as “geeb,” is a transparent liquid solvent.
It is a prodrug—that is, the body naturally transforms it into the illicit chemical GHB—for GHB NembutalHouse.
Powdered gamma-butyrolactone, It smells almost exactly how you would expect an industrial solvent to smell, and it is offered on the black market under the names “rust remover” and “alloy cleaner.”
It is difficult to store, needing. It requires a glass bottle or a bottle made of a certain kind of plastic, which makes storage difficult. It is able to melt through most polymers. Delicious!
