The substance - full name gamma
butyrolactone is closely related to the banned gammahydroxybutrate (GHB) drug.
While GHB itself has not been sold over the counter in the United States since 1992, products containing gamma
butyrolactone (GBL), a chemical converted in the body to GHB, still can be found in a number of dietary supplements sold in health food stores and gyms.

One of the more worrisome analogues of GHB is a widely used chemical solvent, gamma
butyrolactone (GBL).
Some products that contain gamma
butyrolactone (GBL) -- like Renewtrient, Revivarant, Blue Nitro and Gamma G -- are touted as performance enhancers.
SOLVENT MIXTURES may contain small amounts of methylene chloride mixed with other solvents, or new nonflammable stripping agents such as n-methyl-2-pyrrolidone (NMP) and gamma
butyrolactone.
For example, the FDA recently issued warnings about the use of gamma
butyrolactone (GBL) and sought to pressure suppliers into voluntarily recalling the product.
For example, FDA issued a January 1999 warning about illegally marketed and unapproved "dietary supplements" containing gamma
butyrolactone (GBL).
