What the defrenc btween my own testosterone and testosterone replacement by androgel and why treatment of low t are lots of riski'm not my own t?

Testosterone: If you have low testosterone on your own you will benefit from AndroGel or other testosterone therapies. There are potential side effects but that should be monitored by the doctor prescribing your androgel. I monitor psa, hgb/hct, and hdl. If the results indicate possible side effects based on the above labs, discuss this with your doctor.
