GABA is short for gamma-aminobutyric acid and is actually an amino acid although it is often classified as a neurotransmitter due to the way it helps to balance inhibition and excitation in the brain and aids in sleep and relaxation. It also stimulates the production of higher HGH (human growth hormone) levels. (HGH is beneficial in reducing fat levels while increasing muscle, among other things).
Due to the positive effects GABA has on the nervous system, many subjects have reported improved sleep cycles, sleeping more restfully and awakening feeling more refreshed, as well as dreaming more vividly. GABA also acts to stabilize blood pressure and has an analgesic effect as well.
While GABA is most effective when injected, GABA is still highly effective when taken orally. Between 2 and 5 grams are required to achieve any effect, and research has shown that it is useless to take more than around 18 grams.
For the bodybuilder, the stimulation of HGH is benefit enough since only 5 grams of oral GABA increases HGH levels an average of 5 times just an hour and a half after it is taken. When you add in its ability to help you relax and sleep peacefully, its pain- killing effect, and its ability to assist in keeping blood pressure levels stable, it quickly becomes obvious that this is a “must” for any serious builder.
