HCG: (Human Chorionic Gonadotrophin)

Pregnyl by Organon. 5,000 to .20,000 IU (International Units) per 10 cc vial. This drug is not a steroid but it is widely used in athletics today. HCG is a natural protein hormone secreted by the human placenta and purified from the urine of pregnant women.
This hormone is not a male hormone but mimics the natural hormone LH (Luteinizing Hormone) almost identically. LH stimulates
the production of testosterone by the testis in males. HCG sends the same message and results in increased testosterone production
by stimulating the leydig cells of the testis. HCG is used to treat women with certain ovarian disorders and it is used to stimulate the testes in hypogonadal men.

Athletes use HCG to increase the body's own natural production of testosterone which is often depressed by long term steroid use.
When steroids are used in high dosages, they can cause a false signal to go to the hypothalamus that results in a depressed signal to the testicles. Over a period of weeks, this depressed signal causes the testicles to atrophy. To avoid this, athletes will use HCG to keep an artificial signal going to the testis.

When administered, HCG raises serum testosterone very quickly. A rise in testosterone first appears about 2 hours after injecting HCG. The second peak occurs about 2 to 4 days later. HCG therapy has been found to be very effective in the prevention of testicular atrophy as well as to use the body's own biochemical stimulating mechanisms to increase plasma testosterone levels during
training. Some steroid users find that they have some of their best strength and size gains while using HCG in conjunction with
steroids. This may well be due to the fact that the body has a high level of natural androgens as well as the artificial steroid
hormones at that time. The optimal dosage for an athlete using HCG has never been established, but it is thought that a single shot of 1000 to 2000 IU per week will get the desired results. Cycles on HCG should be kept down to around 3 weeks at a time with an
off cycle of at least a month in between. For example, one might use the HCG for 2 or 3 weeks in the middle of a cycle, and for 2 or
3 weeks at the end of a cycle. It has been speculated that the prolonged use of HCG could repress the body's own production of
gonadotrophins permanently. This is why short cycles are the best way to go. The side effects from HCG use include gynecomastia, water retention, increased sex drive, mood alterations, headaches, and high blood pressure. HCG raises androgen levels in males by up to 400% but it also raises estrogen levels dramatically as well, This is why it can cause gynecomastia. Other side effects seen from HCG use include "morning sickness like" symptoms (nausea and vomiting). There have been no cases of overdose complications with the use of HCG nor have there been any associated carcinomas, liver or renal impairment.

HCG was at one point looked at to see if it could cany the AIDS virus, due to the fact that it is biologically active, but the latest word is that this could not be possible in any way. HCG must be refrigerated after it is mixed together and it then has a life of about 10 weeks. It is taken intramuscularly only. This drug is often available by order of a physician if you show symptoms of hypogonadism.
