When it comes to muscle building, anabolic hormones rule. We mean the natural anabolic hormones your body produces, such as Growth Hormone, Insulin, and the King of them all, Testosterone. No doubt about it, when the talk turns to increasing your own body’s production of anabolic muscle building power, nothing beats testosterone and for good reason! It’s well known that testosterone has a wide range of anabolic functions in the body, including key roles in promoting muscle growth, enhancing sex drive, and improving stamina. Not to mention, as we begin to age, our natural levels decline – who wants that?
