Human chorionic gonadotropin (best human growth hormone for sale) – a hormone produced by the placenta during pregnancy in women.However, with urine this hormone is excreted unchanged. Then extracted, purified and used in the creation of drugs, whose composition is a member. Human chorionic gonadotropin has similar biological properties, as well as luteinizing hormone (HCG or gonadotropin). The latter is formed in the human brain pituitary.
Research scientists and physicians have shown the ineffectiveness of this drug when ingested in food supplements.
Today, different pharmaceutical companies produced a large number of products containing the hormone HCG.After intramuscular administration of the drug is well absorbed. The half-excretion time of several hours, with the effect of a single injection of the drug persists for 5-6 days.
The injectable human chorionic gonadotropin is a dry substance enclosed in a vial (bottle). To this vial containing the hormone HCG, ampoule supplied with fluid intended for dissolution of the drug. Most often, the liquid substance is sodium chloride. The powder is highly soluble. The resulting mixture should be administered intramuscularly or subcutaneously. When not using the whole remainder of the liquid to be hermetically sealed in a container and put in the refrigerator. HCG powder it is important to keep in a dry, dark place at a temperature no higher than 25 degrees Celsius.
Effects of gonadotropin
It stimulates the synthesis of sex hormones in the testes, so has the same range of effects as testosterone.
It stimulates spermatogenesis.
It enhances the development of sexual organs and secondary sexual characteristics.
In women, it stimulates the production of progesterone by the corpus luteum, triggers ovulation and supports the development of the placenta.
Side effects of gonadotropin
When receiving HCG may have the same side effects as with testosterone administration. The use of gonadotropin in large doses or for a long time leads to the suppression of secretion of gonadotropin-releasing hormone, and therefore violated the physiological function of the hypothalamic-pituitary-testes. Large doses (2000-5000 IU) is not recommended for longer than 20 days, but according to Michael Scally, MD, and provided a number of studies, desensitization of the testes does not occur if the dosage is 500 IU hCG is administered less frequently or 3 times a week. This protocol can be considered safe even for 1-2 months.
HCG is not a steroid but it is widely used in athletics today. HCG Prengyl is a natural protein hormone secreted by the human placenta and purified form the urine of pregnant women. This hormone is not a natural male hormone but mimics the natural hormone LH (Luetinising Hormone) almost identically. This LH stimulates the production of testosterone by the testis in males. Thus HCG sends the same message and results in increased testosterone production by the testis due to its effect on the leydig cells of the testis.
