I am 56 years of age. I have lifted weights most of my life . Never taken PEDs and I am still solid. I understand that the ability to gain muscle is related to the amount of
testosterone a man produces. When I was young I would wake up with an erections frequently. If I see an attractive woman etc but not anymore. I'm no longer confident that I can perform when my girlfriend initiates. And have resorted to Cialis. I still have no problem gaining muscle why is it that my libido is so low
