Dr. Knapp provided no information as to ALL that could possible explain the fact that I lost 2 inches in height in the last 2 years, I have insominia, lack of energy, hair loss, loss of muscle mass. His answer to these issue and my chronic fatigue was to offer viagra as a solution. In the past, after a 6 week protocol of testosterone, I felt invigorated and more alert. when I stopped the protocol, I felt very bad again. This might lead one to think that some sort of hormone treatment and NOT viagra would help in some way. I felt he wasted valuable time by not looking at ALL possibilities. This man thgouht I just wanted to have sex. MY INTENTION IN SEEING HIM WAS TO FEEL BETTER AND GET WELL. He did nothing to assist in that process. Not one offer to consider what I had told him. I believe he is a poor example of a good doctor.
