So tommorow I go to my doc.

What should I telly Endo tommorow. Though my level was tested at 757 and free test 62.5. My libido is still low. Any chance my Endo can put me on something?
 
I do know the ref range for the test was 250-1100,free test 46-224. Maybe I should ask my endo for other blood work?
That's Quest labs calculated free T in pg/ml. Many people have started TRT due to free T that low. 62.5 pg/ml is officially hypogonadal according to the guidelines of multiple medical organizations when accompanied by low T symptoms. Free T is the primary determinant of eugonadism or hypogonadism, NOT total testosterone. What is your SHBG value? It must be quite high.

Mainstream endocrinologists are unlikely to treat you based on the combination of free T and low T symptoms when your total T is that high. You may have to shop around for someone more open-minded or someone who specializes in TRT.

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.
