The normal level of testosterone in your bloodstream
is between 350
and 1,000 nanograms per deciliter (ng/dl). Medications include oral, intramuscular
and transdermal agents, but results vary a lot. Before you start any medication, I suggest you try a natural approach: physical exercise + DHEA, vitamins C,D, B, E and fish oil. Make sure you're not taking any meds that may influence your hormone levels, e.g. finasteride (brand names Propecia, Proscar) for male pattern baldness.
