I am 50 yrs old and for the last 6 months have seemed to be tired all of the time, no energy. I have gotten supplements and nothing seems to help. I am 6 2 tall and weigh 230 pds. I weighed 256 a year ago, lost 46 and have gained 20 back. but 6 months ago I was had only gained 10 pds back. I was checked for low testosterone and stated that although my levels were a little low, were still fairly normal. I am just do not see to have the energy. I work out, little weights and 50 minutes of aerobics (stairstepper), 5 days a week, but I struggle to get through the workout. Anything you can provide would greatly help.
