Growth hormone (growth hormone, STH, HGH, somatotropin, somatropin) is the peptide hormone of the anterior lobe of the pituitary gland, which is used in sports for the formation of muscle relief. Growth hormone or somatotropin (from the Latin soma – body) got its name because in young people it causes a pronounced acceleration of linear (long) growth, mainly due to the growth of long tubular bones of the extremities. The basal concentration of growth hormone in the blood is 1-5 ng / ml, during the peaks can rise to 10-20 and even 45 ng / ml.
Growth Hormone in Bodybuilding
Initially, growth hormone drugs began to be used for medical purposes, but almost simultaneously this hormone was widely used in sports, which is associated with its ability to increase muscle mass and reduce fatty layer. The first preparations of growth hormone were an extract of the pituitary gland of corpses and only in 1981 a recombinant drug of somatotropin was made.
In 1989, somatotropin was banned by the Olympic Committee. Despite the fact that the use of somatotropin for athletic purposes is prohibited, in the last decade the sales of the drug have increased several times. Mainly, growth hormone is used in sports, especially in bodybuilding, where it is combined with other anabolic drugs.
