How does this medication work? What will it do for me?
Testosterone gel belongs to a group of medications known as androgens (male hormones). It is used to treat men who have testosterone deficiency.
Testosterone is a sex hormone that produces "male" physical characteristics and increases sex drive. This medication works by replacing the testosterone that would normally be produced by the body. Testosterone gel should only be used if testosterone deficiency has been confirmed by symptoms and blood tests.

Apply the gel to a clean, dry area of non-broken skin on the shoulders, or upper arms. Do not apply the gel to the genitals or to any damaged skin. After applying the gel, let it dry for a few minutes, then cover it with clothing and wash your hands with soap and water to avoid getting the medication on other people’s skin. Wait at least 2 hours before, showering, or swimming. After applying the gel, allow it to dry completely before smoking or going near an open flame.
