I will agree that "low T" is being pushed today mainly because of new less medically invasive way of administering this hormone such as Testim gels. (no one like to have a shot every week or every other week)
But for the patient who really needs it, there is no substitute to the weekly or by-weekly injection, because the gels or patches are not very efficient.
Again a person with very low or no testosterone is not a pleasant way to live--and the side effects should be next to none unless pre-existing conditions exist.
Similarly not taking hormone replacement for hypothyroidism or any other vital hormones would be dangerous with very poor health and shortened life span!
