I have experienced very good results using CLA with decaffeinated green tea extract for a stimulant-free fat-loss stack. However, as DmitryWI has noted, higher doses work best. I personally take 4 grams of CLA three times a day. I'm pleased with the results, but not the price. As soon as my supply of CLA runs out, I'll be trying SesaThin liquid with the green tea extract instead.
