Many men like to use testosterone gels and patches. Gels tend to be messy and less convenient than other treatment modalities. In addition, there can be a risk of unintentional transmittal to children or others with whom you may have physical contact with the use of gels. Testosterone patches can create a significant rash at the site of application, or do not stick well, especially in the summer months. At T4MEN, we regularly employ intramuscular testosterone injections because of their clinical effectiveness and convenience. You’re a man don’t be scared of a little needle!
