OstroVit GH Booster Extreme is a complex food supplement combining amino acids, vitamins and minerals. The piperine content enhances absorption of the active ingredients.
L-arginine alpha-ketoglutarate (AAKG) - a synergistic compound combining the arginine amino acid and glutaric acid (a citric acid cycle product).
Gamma-amino-butyric acid (GABA) - a non-protein amino acid and neurotransmitter found mainly in the hypothalamus and extrapyramidal system. Also present in green tea, soya, fermented products and dairy.
L-ornithine HCl - an endogenous amino acid synthesised in the body in the presence of arginine. Natural sources include meat, fish, eggs and dairy.
L-lysine HCl - essential amino acid not produced by the body. Found in dairy, meat and fish.
D-aspartic acid (DAA) - endogenous amino acid produced primarily in the pituitary and hypothalamus. Found in animal-derived foods, asparagus, avocado and oats.
