23G vs. 25G: What Needle Size is Best for Testosterone Injections?
When administering testosterone injections, the gauge of the needle—23g versus 25g—plays a crucial role in determining the ease and comfort of the injection process. A 23-gauge needle is thicker and typically used for drawing up the testosterone medication due to its larger bore. However, for actual injection, a 25-gauge needle is often preferred as it is thinner, potentially making the injection less painful and reducing tissue trauma. The choice is influenced by factors like injection site and muscle mass.
