HCG (Human Chorionic Gonadotropin) Pregnyl

HCG Prengyl's effect

Pregnyl by Organon. 5,000 to 20,000 IU (International Units) per 10 cc vials. 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.

HCG Pregnyl increases the body's production of testosterone

Normally this drug is used to treat women with certain ovarian disorders and it is used to stimulate the testis of men who may be hypogonadal. Athletes use HCG Pregnyl to increase the body's own natural production of testosterone which is often depressed by long term steroid use. Also when it is used in high dosages they can cause false signals to the hypothalamus that results in a depressed signal to the testicles. Over a period of weeks of this depressed signal the testicles ability to respond to any signal from the pituitary becomes very weak, which results in testicular atrophy. To avoid this athletes will use this drug to keep an artificial signal going to the testis and preventing testicular atrophy. When administered, HCG Pregnyl raises serum testosterone very quickly. A rise in testosterone firs appears in about two hours after injecting. The second peak occurs about two to four days later.

HCG Pregnyl prevents testicular atrophy

HCG Pregnyl therapy has been found to be very effective in the prevention of testicular atrophy and to use the body's own biochemical stimulating mechanisms to increase plasma testosterone level during training. Some steroid users find that they have some of their best strength and size gains in conjunction with the steroids. This may wee be due to the facts that the body has high level of natural androgens as well as the artificial steroid hormones at that time.
