For me it is effective. I have three friends that tried HCG drops. One was not consisted and didn't follow the procedure, but she still lose weight. She has weight of 62 kgs and dropping HCG drops under her tongue lead her to lose 60 kgs in a month. Another friend became a habit to drop HCG under her tongue. She also followed the procedure for a month as well, she lost 5 kgs in a month. Another one is not consistent with HCG drops but is addicted in working out. She always go to the gym during Saturday and do some cardio exercises during Wednesday. She lost 3 kgs. From this experience, I really want to try HCG drops but I don't have the money. For my observation, even if you don't follow the procedure, you still lose weight. The second friend said that HCG drops is effective in losing your appetite. She don't like too sweet coffee and snack foods. With HCG she introduced herself to vegetable too. I think drops really works.
