I really like Thermo CLA
So far so good, Thermo CLA has given me energy and has helped me control my appetite. When I don't take this pill I tend to over eat. I take only half a dose of Thermo CLA mid morning when I need an energy boost and appetite control.

The work
I hardly have any change using other products, but this is doing the job. I take it about thirty minutes before hitting the gym. I normally do not sweat, and now I sweat! I started doing a little more cardio and watch what I eat and I have lost about 24 lbs. Keep in mind everyone is different, so you have find what regimen works for you while you are taking it.
August 10, 2017
They work, but you have to put in the work.
No nonsense, these work, but you're not going to lose weight taking them unless you're dieting and working out ( which is the case with most work out things). If you buy these and expect to lose weight eating normally and not exercising, then you're the problem, not the product. I take two before working out and I'm sweating like crazy. Good stuff.
