    Testosterone Levels Too High?

    I’ve been on TRT for 8 months. Started out at .10 per day and then they increased to .15 per day and then to .20 per day. My T levels increased moderately at first from 250 total to 500 total. I don’t have the data on free initial T handy. At 500 total I was at 74 free. Then it went up to 1400...

    Upping my dose

    Hey Guys, I've been on Trt for 5 months now and have seen some benefits but would like to see more. Is this enough time on it to really gauge if I need to go up yet and if so, is there any reason to go from 200ng weekly to 250ng weekly vs straight to 300? Any feedback is great appreciated.

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.
