    Do estradiol levels "move" in parallel to test levels?

    That greatly depends on your aromatization enzyme activity. It typically is not a linear dose dependent response. Keep Es in check with Aromasin.

    lower SBHG with Proviron

    The all knowing FDA does not approve of human use. You cannot have it prescribed. I have crazy high SHBG that was stealing most of my free T even on heavy handed TRT. You'll have to do your own homework to find a source that is reliable.

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.
