Firstly I was unaware from HCG, what is HCG?
Human chorionic gonadotropin:
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.

From where you guys buy HCG, I was buying it from alldaychemist, but it is no more on AllDayChemist, So now I prefer to buy it from ReliableRx Pharmacy. Really good and online pharmacy. Had a better experience while dealing with it.
