How To Raise Libido

Do they have anything to do with libido?

I have an ongoing battle with iron / ferritin / hematocrit

Who knew!

Sit back and take a good look at your most recent labs.....clear as day.....your trough FT level is too high which is going to drive up your RBCs/hemoglobin/hematocrit.

Not only are your RBCs/hemoglobin/hematocrit elevated but top it off that you have crashed your ferritin from way too frequent blood donations to try and control your elevated RBC's/hematocrit.

Again as I have stated numerous times on the forum although TT is important to know FT is what truly matters as it is the active unbound fraction of testosterone responsible for the positive effects.

The only way to know where your FT truly sits is to have it tested using an accurate assay such as the gold standard Equilibrium Dialysis or Ultrafiltration (next best).

You are injecting 140 mg T/week (70 mg every 3.5 days).

Although your trough TT 707 ng/dL is far from absurdly high your trough FT is high due to your lowish SHBG 16 nmol/L.

At least you had your FT tested using one of the most accurate assays (Equilibrium Ultrafiltration).

Your estradiol, RBCs/hemoglobin/hematocrit is elevated due to your high trough FT level, and keep in mind that peak levels can be much higher.

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.
