Finally Dr. Geo interviews the grandmaster of T!


* in my experience if its <100 pg/mL (10 ng/dL) and the guy has symptoms I'll treat them





If you’re 55, 60, 65+ and dealing with low energy, low libido, ED, or you’ve been told testosterone therapy (TRT) is dangerous for prostate cancer—this episode is for you.

Dr. Geo sits down with Dr. Abraham Morgentaler (Harvard-trained), founder of the first comprehensive Men’s Health Center in the U.S., co-founder of the Androgen Society, author of the bestseller Testosterone for Life, and winner of the 2024 Grandmaster in Testosterone Award.




In this conversation, Dr. Morgentaler explains how the old “testosterone causes prostate cancer” dogma took hold, why it’s being challenged, and what men should understand today about:


* TRT and prostate cancer (past, present, and what’s changing)

* Why FREE testosterone matters more than total testosterone for symptoms

* The importance of listening to patient symptoms, not just “a number”

* Testosterone options: injections, gels/creams, pellets, oral testosterone

* What men should ask their doctor if they have low testosterone, active surveillance, or history of prostate cancer treatment





This episode is educational and designed to help you walk into your next doctor’s visit with better questions and clearer understanding.

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.
