Bodybuilding Benefits: fat loss and boosting testosterone levels

How It Works: Forskolin breaks down fat, allowing it to be more readily pulled out of cells. Once the fat has left the cell, the body can burn it for energy. Forskolin also directly boosts testosterone levels.

Dose: 20 to 50 milligrams of forskolin, two to three times per day before meals
