How common is it to have to adjust testosterone dose as you age? I've been on TRT for around 12-13 years. I've always used 100mg a week and my total testosterone has run around mid 900's. My E2 has been around mid to lower 40's and I've not been using anastrozole. My last 2 blood draws have shown me with total testosterone around mid 600's and my E2 in the lower 50's. I haven't gained weight or changed my diet or training routine. Is this something that is common as a man ages? My doctor wants me to start anastrozole at 1 tablet per week.

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.
