WHAT DOES TESTOSTERONE DO?  Testosterone is an important hormone for muscles. It:

  • Maintains heart muscle protein synthesis
  • Promotes coronary artery dilation, & therefore improves blood flow to the heart
  • stimulates the production of red blood cells
  • Maintains a positive balance of Calcium, Phosphorus, Potassium, & Nitrogen in the bone (thereby promoting and supporting bone health)
  • Increases the incorporation of amino acids & protein synthesis in muscles, liver, & kidneys, thus stimulating their growth & metabolism.
  • Increases the breakdown of fat, while decreasing the breakdown of amino acids.
  • Increases basal metabolism
  • Regulates oxidation.
  • Increases creatine storage (a muscle & digestive tonic) & decreases loss of creatine in the urine.
  • Effects new RNA synthesis & the DNA template in the nucleus.
  • Increases cell division in certain tissues (if you have a prostate cancer cell in your prostate, this is a bad thing)
  • Essential for reproduction & maintenance of male sexual characteristics (like beard and body hair growth), organs & behavior
