Growth hormone is now produced by recombinant DNA technology and is prescribed for a variety of reasons. GH therapy has been a focus of social and ethical ...
The classifications of substances as performance-enhancing substances are not entirely clear-cut and objective.

Genes for human growth hormone, known as growth hormone 1 (somatotropin; pituitary growth hormone) and growth hormone 2 (placental growth hormone; growth hormone variant), are localized in the q22-24 region of chromosome 17 [7] [8] and are closely related to human chorionic somatomammotropin (also known as placental lactogen) genes.
Peptide hormones are water-soluble hormones composed of a few amino acids that introduce a series of chemical reactions to change the cell's metabolism. Examples of peptide hormones and analogues are human growth hormone (hGH), human chorionic gonadotropin (hCG), and erythropoietin (EPO). [2] Insulin, synthroid and forteo are not banned. [2]
It is a key mediator of anabolic activities in numerous tissues and cells, such as growth hormone-stimulated growth, metabolism and protein translation. [17] Due to its participation in the GH-IGF-1 axis it contributes among other things to the maintenance of muscle strength, muscle mass, development of the skeleton and is a key factor in brain ...
