I am newbie; never been on TRT; TT 535 FT 67 SHBG 33 (age 59)
Besides Dr. Khera and Dr. Lipshultz, can I get some recommendations for TRT Urologist in Houston, Texas. The reason I ask is getting in to see these guys takes a long time. In Dr. Khera case first available is August.

How do you feel overall?
What time was your labs done and did you fast?

What testing method was used for free testosterone?

Always post the testing method used/reference ranges otherwise we are shooting in the dark here.

Although TT is important to know FT is what truly matters here as it is the active unbound fraction of T responsible for the positive effects.

The only way to know where your FT truly sits is to. have it tested using the most accurate assay the gold standard Equilibrium.

Otherwise you would need to use/rely on the next best testing method which would be the go to linear law-of-mass action Vermeulen (cFTV) which will give a good approximation.

Just keep in mind cFTV tends to slightly overestimate.

Highly doubtful you had it tested using cFTV as your FT would be higher.

With a descent TT 535 ng/dL, normal SHBG 33 nmol/L, Albumin 4.3 g/dL (default) your FT 11.4 ng/dL would be far from low but under where a healthy young natty male would sit cFTV 13-15 ng/dL.

Again keep in mind if you had your FT tested using the most accurate assay gold standard ED than it would most likely come back lower.

FT <5 ng/dL would be considerd low.

FT 5-9 ng/dL would be considered the grey zone where some men may experience symptoms of low-T.

FT 10-15 ng/dL would be healthy.

FT 20-25 ng/dL would be high-end/high!
