I am going to apologize in advance for being technologically challenged. I can't figure out how to answer individual quotes from people (like EyeDentist did with me) nor was I able to successfully cut and paste some info regarding "optimal T levels".
I readily admit that optimal T levels are subjective. I based my numbers mainly on information from the following article:
Simon, D., Nahoul, K., & Charles M.A. (1996). Sex Hormones, Aging, Ethnicity and Insulin Sensivity in Men: An Overview of the TELECOM Study. In Vermeulen, A. & Oddens, and B. J. (Eds.), Androgens and the Aging Male (pp. 85-102). New York: Parthenon Publishing.
The chart I wanted to post listed age levels ranging from <25 up through 50-59. Each age range listed, among other things, TT levels for men in the 95%ile. The lowest 95%ile TT level was 45-49 at 846 ng/dl and the highest was for 25-29 at 1005ng/dl.
I would imagine many men could have what most consider good T numbers, but still feel nowhere near as good as they did in their 20's. They may look and feel better than their contemporaries, but not like their old selves. This is why I posed the question of attempting to reach "optimal" T numbers. In reality, maybe it's more appropriate to say attempting to re-acquire the youthful qualities that T can deliver. All of this is assuming an otherwise healthy individual, no thyroid issues, etc. Just purely declining T levels over the years.
From a medical viewpoint, I can only think of 2 reasons not to pursue this. First, exogenous T will raise one's hematocrit level, which in some individuals would be detrimental to their health. Second, as mentioned by EyeDentist, there are no long term studies on TRT. I have been unable to find any conclusive evidence stating exogenous T kept at physiologic levels is harmful to the body(assuming E2 is controlled, etc). I'm really hoping for someone better read than I to provide any additional evidence stating the TRT for non-hypogonadal males is ill-advised/dangerous. Otherwise this becomes a purely philosophical debate.
Thanks for your input.
