Uses Of Testosterone Undecanoate

Testosterone undecanoate is a male sex hormone. It works by replacing or supplementing the testosterone that is naturally made in the body. FDA approved testosterone undecanoate is a long-acting man-made version of testosterone, the natural male sexual hormone. Testosterone is responsible for the normal growth and development of male sex organs and characteristics. It includes growth and development of male organs of penis, testicles, prostate, body hair, vocal cord thickening, and muscle and fat distribution.
