3 months ago on a whim at a local health food store purely because it looked interesting. I had relatively low expectations (my husband rolled his eyes when I came home with "another weight loss pill") going into it, but I am pleasantly surprised at how much I like it. My mornings start with the recommended dosage with a healthy breakfast and 20-30 minutes of cardio before I go to work. I feel more energized and feel less of an urge to snack between meals. I wouldn't call it an "appetite suppressant" because I do still feel like eating sometimes, but not "hungry" if you know what I mean. It's very manageable and I recommend it to anyone looking for a natural product like me.
