    Where to get Testosterone prescriptions?

    If you’re in the DFW area I can recommend an outstanding urologist. I had the same issue with my PCP. As a rule they simply don’t have sufficient experience managing TRT. Anyone can prescribe it but not everyone can properly manage it. I recently relocated out of the country and I have the...

    Starting Nebido

    staggering the dose makes sense. I mainly want to stay away from one huge dose every 4-6 weeks. I’m trying to keep a fairly consistent level.

    Agreed. And what really gets under my skin is my own ignorance at the onset of therapy. I was admittedly naive about TRT and if he had told to go home and drink a gallon of testosterone I probably would have. Because had I known then what I know now I would have asked to be referred to a...

    Cessation Advice

    I'll try to keep this short. A little over a year ago my GP put me TRT at 300mg/wk. This was after an initial blood test and a second to confirm the first. I was left on that dosage for a year until this past November when I had a yearly physical and my labs revealed my testosterone level was...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
