Unfortunately for dieters, the FDA has banned the use of hCG injections as a weight loss aid. Because pharmaceutical grade hCG must be prescribed by a doctor, it has become increasingly difficult for dieters to purchase hCG injections in the United States. If you want to purchase hCG injections, you may have to buy hCG injections online. However, dieters must understand that this can be dangerous. If you aren�t getting hCG though a physician, you have no way of knowing whether you are using high quality hCG. Before purchasing hCG injections, you may want to consider purchasing homeopathic hCG drops instead.
