Thermogenic fat burners are products that are intended to increase your metabolic rate to help you burn calories and lose weight. These supplements differ from other weight management products, such as fat blockers, in that they typically contain stimulants, such as caffeine. Men's thermogenic fat burners may also include testosterone-enhancing ingredients, as that hormone is involved in metabolism.
BPI Sports RoxyLean ECA
BPI Sports RoxyLean ECA is a thermogenic fat loss burner that contains multiple stimulants, including caffeine and 1,3 dimethylamylamine, also known as geranium extract. In addition, BPI Sports RoxyLean ECA contains herbal extracts, such as citrus limonium, which research from the May 2006 issue of the "Journal of Agricultural and Food Chemistry" found has lipolytic, or fat-burning, activity.
Betancourt Nutrition Ripped Juice Concentrated
Betancourt Nutrition's Ripped Juice Concentrated is a fat-burning product that contains numerous stimulants, such as yohimbine and caffeine as well as herbal extracts such as green tea extract and hoodia gordonii. In addition, Betancourt Nutrition Ripped Juice Concentrated contains amino acids, such as carnitine.

Myogenix Black Ops
Myogenix Black Ops is a thermogenic fat burner that does not contain any stimulants, but it may still promote fat loss and weight management. This product contains the amino acid theanine as well as 3-acetyl-7-oxo-dehydroepiandrosterone, also known as 7-keto.
