Also Known As: hCG, human chorionic gonadotropin, 001 hCG
In molecular biology, human chorionic gonadotropin (hCG) is a hormone produced by the syncytiotrophoblast, a component of the fertilized egg, after conception. Following implantation, the syncytiotrophoblast gives rise to the placenta. Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not pregnant can lead to a cancer diagnosis. However, it is not known whether this production is a contributing cause or an effect of tumorigenesis. The pituitary analogue of hCG, known as luteinizing hormone(LH), is produced in the pituitary gland of males and females of all ages. As of December 6, 2011, the United States FDA has prohibited the sale of "homeopathic" and over the counter hCG diet products and declared them fraudulent and illegal.
HCG itself is classified as a prescription drug in the United States and it has not been approved for over-the-counter sales by the FDA as a weight loss product or for any other purposes, and therefore neither hCG in its pure form nor any preparations containing hCG may be sold legally in the country except by prescription. In December 2011, FDA and FTC started to take actions to pull unapproved hCG products from the market. In the aftermath, some suppliers started to switch to "hormone-free" versions of their weight loss products, where the hormone is replaced with an unproven mixture of free amino acids or where radionics is used to transfer the "energy" to the final product.
