As an anabolic steroid, Fortesta is classified as a Schedule III
controlled substance in the United States. This means that special laws and regulations control its sale and use.
Brand-name Fortesta is made by Endo Pharmaceuticals, Inc.
Fortesta contains the hormone testosterone in a special gel that is applied to the skin just once a day. The gel dries on the skin, and testosterone is absorbed into the bloodstream throughout the entire 24-hour period. Fortesta helps increase testosterone to a normal level.
Fortesta is used as a gel, not taken by mouth, because it would have little effect on testosterone levels if taken orally. When medications are taken by mouth, they must first pass through the liver before they reach the bloodstream. The liver metabolizes testosterone extensively before it has a chance to reach the bloodstream, and significant blood levels of the medication cannot be achieved.
However, when testosterone is applied to the skin, it bypasses the liver, allowing significant amounts of the hormone to reach the bloodstream.
