GBL Drug Test

What is GBL Drug Used For?  What is GBL drug? Gamma butyrolactone (GBL) is a chemical. People use it as medicine. Be careful not to confuse GBL with gamma-hydroxybutyrate (GHB) or butanediol. Both drugs GBL and GHB are two closely related drugs. Both are often used recreationally in club settings to achieve a euphoric, disinhibiting effect and by bodybuilders to promote growth hormone production. Because of GHB’s chemical similarity, GBL is a “prodrug” of GHB, meaning it is converted (metabolized) into GHB in the body, and its effects are identical. GBL itself is pharmacologically inactive, but it is converted in the body by lactonases to GHB, the active agent. Because it is more lipophilic than GHB, GBL is absorbed more rapidly after oral administration and has a faster onset of action than GHB. Apart from that, the actions of the two drugs are identical. One ml high-purity GBL is about equivalent to 2.5 g GHB. GHB occurs naturally in the central nervous system (CNS) and is presumed to be a neurotransmitter. There are GHB receptors in the CNS, but GHB also acts as an agonist at the gamma-aminobutyric acid B (GABAB) receptor. At low doses, it has a euphoric effect, promoting confidence…
