I have been taking this product for over 6 months now and I truly feel I would be lost without it! I am a nurse and I work long hours and this helps curb my appetite and provides me with lots of energy. I can definitely tell a difference if I accidentally miss a day of taking it. It really helps me get through my day without feeling wiped out. I go in spurts with watching what I eat/eating healthier and working out. The plus side with Catalyst XT is even if I “fall of the bandwagon” in regards to eating healthier and working out it has still helped me maintain my current weight. However when I am eating healthier all the time and working out a couple of times a week the weight just falls off. This is truly a wonderful product and I will continue to take it daily!
