AST GABA 100 gr contains Gamma Aminobutyric Acid, which has growth hormone (GH) elevating effects that rival those of potent pharmaceutical compounds. Gamma Aminobutyric Acid is a type of amino acid called a neurotransmitter. Neurotransmitters carry nerve impulses throughout the body. GABA is found in high concentrations in the hypothalamus region of the brain, which is responsible for regulating instinctive bodily functions, such as circadian rhythm (sleep cycles), core temperature, and pituitary gland function. This suggests that GABA is involved in hypothalamic-pituitary function.

Studies have shown that people can experience a 550% increase in growth hormone levels with just 5 grams of GABA. This is because of its role in the function of the pituitary gland, which is the master endocrine gland responsible for hormone levels in the body. One hormone that is of particular importance to athletes is growth hormone (GH).

GABA has been proven through hundreds of clinical studies to trigger noticeable increases in plasma GH levels. An example of one such medical research study is from the First Medical Clinic at the University of Milan in Milan, Italy, and is titled, “Effect of acute and repeated administration of gamma aminobutyric acid (GABA) on growth hormone and prolactin secretion in man.” A quotation directly from this study states that “In all of the 19 subjects studied, compared with 18 controls, plasma growth hormone levels were significantly increased (above 5 ng/ml) by acute oral administration of 5 g of GABA.” This shows how powerful this amino acid is.

This study showed over a 5 1/2-fold increase in plasma GH levels within 90 minutes of GABA administration, which is a significant increase unmatched by any other nutritional means. Studies on GABA have been performed with both oral and intravenous administration. The oral route is remarkably effective, and certainly more convenient for consumers.
