In this video I describe how to perform a subcutaneous injection of testosterone for by our dinner go hormone replacement therapy. This technique is sometimes used to keep testosterone levels more consistent than with a once weekly intramuscular injection. The twice weekly subcutaneous route allows the subcutaneous fat to act as a reservoir of the testosterone, slowly releasing it over time. This typically leads to more consistent testosterone levels. Side effects of testosterone such as acne are often lessened by twice weekly administration of testosterone.
