Substance Comparison
Alprazolam lasts considerably longer at around 9 hours, while GBL clocks in at roughly 3.5 hours. GBL reaches full onset in ~23 min — noticeably faster than Alprazolam at ~45 min.
Both substances belong to the Depressiva class, making this a common comparison for understanding differences within the same pharmacological family.

Alprazolam wirkt als Agonist am GABA-A-Rezeptor, was zu einer verstärkten Hemmung der neuronalen Aktivität führt und somit anxiolytische und sedative Effekte erzeugt.
GBL wird im Körper zu GHB metabolisiert, das als Agonist an GABA-Rezeptoren wirkt und sedierende sowie anxiolytische Effekte hervorruft.
