I am 64, 5'6" 195 lbs (yes, I know, way too much - it was significantly worse!)

I've been very de-motivated and lazy, spending a lot of time laying in bed reading the internet on my phone. (Being retired. Lets me do that.)

I'm on some psych meds, thoough they haven;t changed in a while.

Type 2 diabetic. pretty well controlled with Victoza - just starting on Metformin in hopes it will allow me to lose morre weight. Most of my fat is visceral - so theoretically if I got rid of that my diabetes can improve and my testosterone levels can be better. Belly fat sucks!

NOTHING wrong with my libido. I've had ED 2 years ago because of too much porn (yes, that's real) but I'm over that - and also one time I got off twice in about 4 hours and things didn't work right for a week or 2. Due to that occasion, plus BPH, I'm on Cialis daily.

ANYHOW, the motivation/depression issues made me wonder if I was a candidate for TRT. Based on test results, I thought I might be, though my endocrinologist didn't.

I ran the first set of results by Defy, and they were game, but the initial startup expense held me off.

BUT I've had another set of test results since that make me wonder if I should even bother.

Both from Quest, but different types of tests.

So the first, from Jan 3 2019:

And the second from May 21, 2019:

The second set of tests appear to have better results, and also to be better *tests* .

It seems the first were an ImmunoAssay for total and some unknown method for Free.

The second test seems to be mass spectography for Total and a Dialysis test for Free, which from my reading seems like a direct measurement of the percentage free using tritiated testosterone.


One reason that I insisted on a second set of tests is that I am just starting on Metformin (Glucophage) for my diabetes, and I read some places that that can reduce Testosterone and testosterone receptors, though it doesn't seem to be established science.


So anyhow, am I in the right place? Or do the second set of numbers say that my T levels are fine?

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.
