    Trouble getting basic Phlebotomy

    I even managed to get a prescription for a phlebotomy! But my blood bank (which took my blood twice last year) refuses to honor this prescription. My private GP doctor also refuses to give me a therapeutic phlebotomy. Any suggestions?

    Hematocrit still high even after Blood donation!

    Do I really have to take an AI like Arimidex during TRT? I think it makes me miserable.

    Given my estrogen levels below - what would happen if I stopped taking my Arimidex 2mg / week (taken for about like 10 months)??

    Can HcG alone (withOUT T-cypionate) help sex drive & increase overall testosterone?

    I think that HcG (Pregnyl) ALONE at slightly higher doses (like 2,000 units/week) improves my libido and mood much better than any T-Cypionate brand I've tried. Get this - I even tried my own local pharmacy brand of "Depo-testosterone"...

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.
