it is a scam pushed by phony doctors and indian pharmacies because it is dirt cheap to produce and they make so much money off of it
it is a scam because it has no health benefits to men or women. all hcg is is extracted pregnant female urine, of course the hcg used today is made in a lab but it still has that chemical structure. it is a hormone that mimics LH.
