Part 4: Human Growth Hormone (HGH)

HGH competes with anabolic steroids in the illicit market of alleged tissue-building, performance-enhancing drugs.

Growth Hormone (GH) stimulates bone and cartilage growth, enhances fatty acid oxidation, and reduces glucose and amino acid breakdown. Healthy elderly men who received GH supplements increased lean body mass by 4.3% and decreased fat mass by 13.1%. However, supplementation did not reverse the negative effects of aging such as declining muscular strength and aerobic capacity. , the true markers of biological age.
