Hello, I'm a 29 yr old female trying to lose 15-20lbs. I was told about a product HCG. I'm looking for advice on purchasing HCG in the oral form. Does anyone know of a good source or site i can obtain this? Does it really work like they say it does? There are several sites offering this product, just trying to find out which one actually works the best. i appreciate any kind of help. Thank you
