Free t symptoms

Are there specific symptoms of low free t or are they the same as tt? If so, how do the symptoms differ?

Is there a possibility of having low free testosterone for years and tt being in midrange(500-600)?

My main worst symptom is brain fog, but motivation, focus, intrusive thoughts, worrying, ect have been with me for years. The brain fog has been around for 4-5 years on and off. Tyia
 
It is possible if you have a high SHBG. Measure total T, free T(by dialysis), and SHBG and see.

"Brain fog" and the rest of your symptoms can be caused by a gazillion things and testosterone may have nothing to do with it.
 
Thanks for responding! These are from a couple weeks ago.

Have you taken any steroids, SARMS, aromataze inhibitors, clomiphene, pills to 'increase testosterone', etc within a month before the tests?

The tests are all normal but show lower testosterone, which leads to lower free testosterone.
 
I haven't taken anything other than vitamin d, zinc, and k2. I am not on trt. I'm just trying to figure out if I will benefit from it and have been for a few years now.

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.
