What is Testosterone gel?

Testosterone gels deliver testosterone through the skin. They avoid injections but introduce important application, transfer and daily-consistency considerations.

Approved-use context

Transdermal testosterone is authorised for replacement in appropriately diagnosed hypogonadism. Different gel brands and concentrations are not automatically interchangeable.

How it works

Testosterone passes through the skin into systemic circulation. Absorption varies with product, application area and adherence to product instructions.

Formulations and schedules

Gels may be supplied in pumps, sachets or unit-dose containers at different concentrations. Only the application sites specified for the exact product should be used.
