AKA: gamma-Amino-beta-hydroxybutyric acid or 4-amino-3-hydroxybutanoic acid
GABOB is a lesser known metabolite and analogue of #GABA, which is available on the Internet under the trade name Gamibetal. It is sold as an anticonvulsant for epilepsy in Europe, Japan, and Mexico.
Structurally GABOB resembles GABA with a hydroxyl group at the 3 position.
GABOB functions as an inhibitory neurotransmitter, which produces anxiolytic and anticonvulsant effects. Studies have shown dose dependent effects of GABOB on #growthhormone levels, although I could not find any that used oral administration.
Users can expect effects similar to GABA but with greater potency; due to GABOB's ability to cross the blood-brain barrier. GABOB should make for an effective sleep/relaxation aid.
