Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Testosterone gel (Testim, AndroGel, Fortesta, Vogelxo) and testosterone enanthate (Delatestryl) are both testosterone replacement therapies used to treat low testosterone levels (hypogonadism) in males. They belong to the same medication class and work by raising testosterone to normal levels. However, they differ in their administration and specific uses. Testosterone gel is applied to the skin once daily, while testosterone enanthate is injected by a healthcare professional into the muscle every 2 to 4 weeks. Testosterone enanthate is also FDA-approved for treating delayed puberty in males and metastatic breast cancer in females, whereas testosterone gel is not. Testosterone gel can accidentially expose others to the medication through skin-to-skin contact, which can cause unwanted side effects in those exposed, while the injection does not have this risk. Common side effects of the gel include skin irritation and acne, while the injection can cause acne, pain at the injection site, and more frequent erections. Both medications can interact with blood thinners, increasing the risk of bleeding.

Testosterone enanthate is a testosterone replacement therapy. It's mainly used in males to treat low testosterone levels and delayed puberty.
