Hello EM,

Let me start by saying this site has an immense amount of information!
Yes I do have a question.
I recently had my testosterone check thru Lab Corp.
Attached see my results.
Being a 55 yo man, are the results in line with my age or should I look further into a TRT?

Thanks Jeff

Your total testosterone would be considered good, but the lowish free T measurement suggests that your SHBG may be on the high side. Best to remove doubt and measure SHBG directly, as the standard free T test is not very reliable. If SHBG is high there aren't any great options, but see this article: High SHBG
 
It's obvious that you have elevated SHBG which is common when one has high normal Total T and rock bottom Free T. Free T needs to be above 15.0 and preferable higher to relieve all symptoms of low testosterone.

TRT is the one thing that can lower elevated SHBG, or rather excess androgens which your body will never be able to do on it's own for the fact that it's not. Your pituitary should be increasing the stimulating hormone LH to increase free testosterone, that's not happening do to a sluggish pituitary gland and is the most common reason for low testosterone worldwide.

You will require supraphysiological levels to ever have enough Free T, something a sick care doctor will not allow do to insurance companies forcing doctors to keep levels under 800, seeking private care is the only way around this limitation.

Be prepared, healthcare systems are mostly inept to manage TRT effectively.

High SHBG can be genetic, hard dieting and abusing the liver with drugs and or alcohol.

With a TT of 643 ng/dL and a sub-par FT I would say as others have stated your SHBG is high.....hence most of your TT is bound up causing low FT which is the unbound active fraction of testosterone responsible for the positive benefits.

Most men do well having FT 2-3% of TT.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
