    Those numbers look pretty good. I'm starting trt this week and my pre trt numbers look similar to yours. Do you mind sharing your trt protocol?

    How did you feel before starting, and how do you feel now? I recently had my labs taken and my free test was the same. I am currently waiting for my first consult with Defy.

    Do My Labs Show TRT a Possibility?

    This is basically what I am trying to avoid. If I wasn't starting to see myself starting to fall off, I wouldn't even consider it. Lifestyle wise I have always tried to stay on top of that. I have always gotten really good sleep but I feel like in the last year or so it's not been quite as good...

    Do My Labs Show TRT a Possibility?

    What lab tests for women?

    My wife has been slowly gaining weight even with a pretty decent diet and activity level. She feels run down as well over the last couple years.

    Do My Labs Show TRT a Possibility?

    Do My Labs Show TRT a Possibility?

    Tanks for the responses guys. Vince Carter, your'e correct in that I should have got free test checked. My thinking going in was that if total test is under 500 I would probably go to defy and at that point they would test everything before making a decision. What I am wondering, is if it were...

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.
