It is best to begin the HCG Protocol when you are able to commit to doing it properly. Women should begin after their menstrual cycle or, a minimum of 10 days prior to its onset. The bottom line is that the Protocol is easiest to stick to when there aren't any major events (like birthdays, holidays, weddings, etc.) or travel. This is because it is necessary to eat foods that need to be prepared at home, at least most of the time. Cooking takes time but allows you to better enjoy the flavors of the foods.
