What Are Peptide Hormones?

Peptide hormones are composed of amino acids connected by peptide bonds. The smallest peptide hormone can be composed of three amino acids, such as thyroid-stimulating hormone-releasing hormone (TRH). Most peptide hormones can be composed of dozens, dozens, or even hundreds and hundreds of amino acids. The main secreting organs of peptide hormones are the lower thalamus and pituitary gland. Peptide hormones such as the gastrointestinal tract, brain tissue, lungs and heart are also found in other organs, and most of them are in the research stage.

(HGH)

hGH is a peptide hormone that is formed in the anterior lobe of the human pituitary gland and produces the most during sleep, and with the increase of age, the production of hGH gradually decreases. hGH can quickly enter the liver, where it is converted to growth mediator-C, which regulates growth and development, immunity and metabolism.

hGH can promote growth and development, promote the division and proliferation of bone, cartilage, muscle and other tissue cells, increase protein synthesis, promote bone growth in childhood and adolescence, and is mainly used in the treatment of dwarfism. It can also promote anabolic metabolism, increase muscle strength, and strengthen tendon strength, so that human muscles are strengthened, strength is increased, and competitive advantages are obtained, which is why it is used as a stimulant. Because of its anti-aging effect, hGH is also used in the field of beauty.

Taking these drugs also carries huge health risks: leading to hypertrophy and deformity of the extremities. Damage to the liver and bones. It may pose a high risk of contracting a fatal disease (such as AIDS), and there have been records of deaths caused by brain virus infection caused by hGH. hGH can suppress the consumption of sugar, leading to high blood sugar and urine glucose; it can also reduce insulin sensitivity and cause glucose intolerance. According to foreign reports, 80% of people who overuse hGH have diabetes and need insulin treatment; leading to menstrual disorders, sexual desire Decrease and impotence etc.

Due to the delayed detection of hGH, no hGH-positive case has been identified so far, so many athletes consider it to be "safe". Marion Jones, who was severely punished for using a mixed stimulant containing hGH, "confessed" himself rather than being detected. David Howman, director general of the World Anti-Doping Agency (WADA), once said: "We know that there are people taking hGH all the time, but they have not been punished accordingly. This has been the case for 20 years." A large number of hGH injections were seized in Coach Stein's luggage; the Italian police also found hGH in the athlete's luggage during the ring bike race. WADA announced at the end of February 2008 that the detection of hGH, the enemy of anti-doping agents and the darling of drug users, has made new progress recently, and new detection equipment is expected to be used in the Beijing Olympics. This will also be a highlight of anti-doping work in the Beijing Olympics.

Governance actions before the Beijing Olympics

Before August 2008, nationwide drug stimulant actions will be carried out. The minimum packaging of stimulant-containing drugs must be marked with the "Athletes Use With Caution" sign. In drug stores in Beijing and other Olympic Games and surrounding cities, except insulin Retailing of anabolic agents or peptide hormones other than insulin is strictly prohibited.
