HCG has always been a controversial topic. This million $ industry is reaping huge profits w/ hcg as many have lost weight using hcg drops/shots/pellets. While theoretically it is claimed that hcg targets the abnormal fat in the body and converts them to energy, the human body is still a mystery and no one is really sure whether it is the 500 cal diet or hcg.
However many doctors claim that you should NOT undergo 500 calorie diet without hcg for the reason that you might do serious dangers to the body especially vital organs.
If you are panning to undergo any treatment, better consult the doctor, prepare yourself and then start with the hcg diet.
