    TRT Restart Protocol after 5 years

    Hello, I am considering going off TRT due to prostate cancer risks. (My father is currently dying from it, and it runs in my family. His own father died from it, too.) I am 48 years old, and began TRT at 43. Never abused steroids. I have been happy on a standard, doctor supervised TRT...

    Attempting restart with Clomid and arimidex (for E2). Logging experience, and ready for input!

    Long story short, I never really got "dialed-in" on TRT. My dosage fluctuated, but I never felt "great." My ending dose was 100mg test cyp (2 shots IM weekly of 50mg) and 600iu HCG (3 shots SQ weekly of 200iu), with no AI. This kept my total T at around 800 measured in my trough, and E2 at about...

    Reboot T production using arimidex?

    Hi Just got back from my appointment with one of my endo's and I have a question related to what was said during our meeting. My last MRI shows that my pituitary gland tumor hasn't been growing the last year and all the bloodwork that has been done the last two years shows that only my T has...

    Does testosterone replacement cause primary hypogonadism?

    I am secondary hypogonadal, and I currently take HCG monotherapy. Together with eating "paleo" and avoiding other foods I'm sensitive to, and focusing on better sleep, etc., I'm feeling more energetic, upbeat and focused. However, I'm still mildly depressed with very little libido, and I don't...

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.
