I had awesome results on Lipo-6. I felt fine. I lost about 60 pounds altogether. There was a lot that went into that... But, the only fat burner that I was on was Lipo-6. It took me about 3 1/2 or 4 months to lose that. Which was incredibly fast. I was running everyday and eating a VERY calorie restricted diet. Also, I took a multivitamin (GNC UltraMega Gold High Potency w/Iron), and about halfway in I got back on protein. Now, I don't recommend losing weight the way that I did... I took myself down to nothing. 5'8" 168lbs. @ 6% bodyfat. When I started my insane burn, I was 5'8" 228lbs. @ 31% bodyfat. For the first two months or so, I didn't touch a weight. Just ran. After that, I started weight training again, but I was still running on the front of my workouts. Lots of water, no food to speak of, just grilled chicken salad until I started lifting again, then it came up a BIT. I started eating more than once a day, took it up to 4-6 times, but I was still eating between 1000 and 1200 calories. I know that all of this seems irrelevant, but I just wanted to point out that those results probably aren't typical of Lipo-6. However, with that incorporated, I lost quite a bit of weight.
I'm back on Lipo-6 again now since I'm cutting. I'm taking it on a 2300 calorie diet, and have been on it for 1 week now. The Lipo-6 has already cut off 3lbs.! For reference, I'm 181lbs. @ 7% bodyfat now. It's pretty wild stuff. Try it and see how you respond to it. It recommend it wholeheartedly.
