    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.

    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.

    Total Waste Of Money
    This thing is total junk. I've had it on 4 occassions. The first two times I took at work and I noticed having head aches so I took them before class and the head aches were back. Just yesterday, I took them 2 hrs before going to the gym and I had to lay down because the head ache was back again. I DO NOT recommend this.

    Product Works - Energy and Appetite Control
    Pros - *I received "Clean" energy when taking these, with no crash or jitters.
    *My appetite was held in check, I could eat a breakfast bar in the morning around 7, and not feel the need to snack or have hunger pains until noon.
    *I lost weight, though I was combining this with diet and exercise.

    Cons - *I grew immune before the end of the bottle. With about 12 pills left, I now hardly feel the energy as stated above, and find myself not being able to hold my appetite as long. I was even able to take a nap after taking 2 pills in the afternoon.
    * As with any thermogenic, you will feel extreme thirst after taking the pills, which in turn causes frequent bathroom breaks.

    Overall, the pills work, but I won't be able to buy another bottle due to the immunity I have developed to their effect.

    Not for me
    I am not sure why so many people love this. It didnt work for me at all. I did not notice any difference at all in weight loss. very disappointed.
    September 14, 2016
    Love it!
    I absolutely love this product! However, I do not recommend mixing with another supplement. I mixed it with Strong Girl and it gave me really bad stomach pains and vomiting. I switched the dosages around a little and same thing. I take CLA everyday in the morning before my meals. I take Strong Girl once a day before my largest meal. My body likes this better. I have lost 30 pounds so far taking the CLA. Took awhile for it to kick in though.
