Low testosterone levels were affecting my quality of life. Tired, loss of muscle mass, poor mood, poor sleep were a result of below minimum bio-available testosterone. Testosterone in and of itself would be helpful but additional medications (DHEA, DPAC) are necessary to keep hormonal balance and my body producing its own hormones. This reduces the chance of any additional issues or a need to increase other medications, including testosterone, as my body adapts to the testosterone shots.
