  Human Chorionic Gonadotropin (hCG)
The human chorionic gonadotropin (hCG) test is done to measure the amount of the hormone hCG in blood or urine to see whether a woman is pregnant.
HCG is made by the placenta during pregnancy.
HCG levels are generally tested in a woman who may have abnormal tissue growing in her uterus, a molar pregnancy, or a cancer in the uterus (choriocarcinoma) rather than a normal pregnancy.

 Human chorionic gonadotropin Summary
Human chorionic gonadotropin (HCG) is a glycoprotein hormone produced by the extraembryonic tissue of the early human embryo.
The presence of HCG in the urine of a woman is indicative of pregnancy.
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the syncytiotrophoblast (part of the placenta).

The human chorionic gonadotropin (hCG) test is done to measure the amount of the hormone hCG in blood or urine to determine whether a woman is pregnant.
HCG is produced by the placenta during pregnancy.
Therefore, hCG levels are usually tested in a woman who may have cancer of the ovaries or abnormal tissue growing in her uterus (molar pregnancy) instead of a normal fetus.

 Fertility-Facts.com ~ Human Chorionic Gonadotropin (hCG)
Human Chorionic Gonadotropin (hCG) is also known as the "pregnancy hormone" as it is produced once a woman becomes pregnant.
HCG monitoring is more useful before the fetal heartbeat is seen (before 6-7 weeks after LMP), usually to rule out an ectopic pregnancy or an early miscarriage.
HCG is first found in the blood as early as 7-8 days after ovulation and within the first 2-4 weeks after fertilization, hCG levels usually double every 48-72 hours.

 Human Chorionic Gonadotropin (HCG) :: Buy Online Steroids
HCG is manufac-tured from the urine of pregnant women since it is excreted in un-changed form from the blood via the woman's urine, passing through the kidneys.
Although HCG causes a quick and significant increase of the endogenic plasma- testosterone level, unfortunately it is not a perfect remedy to prevent the loss of strength and mass at the end of a steroid treatment.
HCG package insert states clearly that HCG "has no known effect of fat mobilization, appetite or sense of hunger, or body fat distribution." It further states, "HCG has not been demonstrated to be effective adjunctive therapy in the treatment of obesity, it does not increase fat losses beyond that resulting from caloric restriction.

 Human Chorionic Gonadotropin/Robert Maragoul
Human chorionic gonadotropin (hCG) is a glycoprotein hormone that was originally identified by virtue of its involvement in reproduction.
The synthesis of hCG starts declining between the 11th and 12th week of gestation and is maintained at a low level throughout the pregnancy, besides the intact hormone, free hCG subunits, enzymatically modified molecules are found in the urine and also in the serum of pregnant women.

 hCG (human chorionic gonadotropin) Levels During Pregnancy

 HCG (Human Chorionic Gonadotropin) Anabolic Steroid Profiles - Steroid . com
HCG is not a steroid, but a naturally occurring peptide hormone, produced by the embryo in the early stages of pregnancy and later by the trophoblast (part of the placenta) to help control a pregnant woman´s hormones (1).
HCG is clinically used to induce ovulation and treat ovarian disorders in women, as well stimulate the testes hypogonadal (underproduction of testosterone) men.
Since HCG increases the body´s natural testosterone levels its use during long or extremely high dosed cycles can be most beneficial were the effects on the hypothalamus causes a depressed signal to the testicles.

 HCG (Human chorionic Gonadotropin)
The activity of HCG in the male body is due to its ability to mimic LH (luteinizing hormone), a pituitary hormone that stimulates the Leydig's cells in the testes to manufacture testosterone.
The main focus with HCG is to restore the normal ability of the testes to respond to endogenous luteinizing hormone.
A combination of both drugs appears to be very synergistic, HCG providing an immediate effect on the testes (shocking them out of inactivity) while the antiestrogen helps later to block inhibition on the hypothalamus and resume the normal release of gonadotropins from the pituitary.

ßhCG is 23 amino acids longer than ßLH (in the C terminus of the peptide), the rest of the ß chain differs only by 24 residues out of 121 and none of these residues are involved in disulfide bonds (Fig.
Furthermore, since nicked hCG is clearly increased in Down syndromes, it is advisable to choose a kit which estimates (overestimates?) this molecular form of hCG.
