Great graphics. Unfortunately, not a great job on showing more data on estradiol benefits. At least he mentions some of the risks of overtreating estradiol. Also, never addressed what “ treat based on symptoms” means. Most symptoms blamed on high estradiol have nothing to do with E2.

It's about Erythrocytosis. Maybe treat based on symptoms vs treat based on numbers. I recall an earlier study which linked E2 to Erythrocytosis, and it employed AI to manage it when E2 was high on modest TT levels.

Why the difference between TU and TE/TC? What dose and injection intervall?
When topical is mentioned it probably means Androgel. Not the same as twice daily high percentage Testo cream. Etcetera

You provided a much clearer correlation, i.e. accumulated free T.

Oral TU is outstanding. Why? That's intriguing.

You would need to listen to the full presentation which includes a Q&A at the end to catch the gist here.

I will be post the link after I am done posting some of the other presentations.

Unfortunately he did not spend enough time on the benefits (bone health, libido & erectile function, metabolic regulation) as the presenters were only given 20-30 minutes.

Dr Khera was the moderator.

Dr. Lipschultz was there too!

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.
