After 3 weeks all my doubts and skepticism had absolutely vanished! I am down, 2 full dress sizes, after losing another 6 lbs. And I still have a ton of energy. Quite often, around the third week of other diets, you tend to run out of steam. But with HCG Ultra my energy levels don't dip, but remain steady throughout the day. My feelings of hunger are crushed and I am even noticing that my stomach is digesting food so much better. No bloating or embarrassing gas after I eat!
