Most studies have found that hCG (stands for human chorionic gonadotropin) has nothing to do with it. The hCG diet limits you to 500 calories a day for 8 weeks while taking hCG, either by getting a shot or by taking a “homeopathic” product, such as oral drops, pellets, or sprays, which you can buy at the store. None of this is approved by the FDA for weight loss. The shots themselves are legal, as long as a health care provider gives them to you. (They're approved to treat fertility issues.) But over-the-counter hCG products are not. The FDA has sent warning letters to several companies that market homeopathic hCG products.

With the tip still in the vial, turn the vial upside down.
