HGH is a combination of Maca, ornithine, arginine and zinc.
Maca is a source of steroidal saponins and vegetable sterols. Sterol skeleton (C27) makes up the fundamental part of steroidal saponins, similar to that building the structure of testosterone. Arginine is an amino acid responsible for various biochemical functions within the body, being a precursor of nitrogen oxide (NO) secretion. For instance, NO is instrumental in the dilation of the blood vessels. Zinc contributes to the maintenance of normal testosterone levels in the blood and normal protein synthesis.
HGH is particularly recommended to professional sportsmen pursuing various sports disciplines, especially strength sports (body building, power lifting, combat sports).
