    Testosterone and Anastrozole starting dose for ED injections

    have you had a chance to run your labs yet? I just read systemlords advice and finally am realizing that a lower dose is better for me. I had it in my head that less than 100mg was no good but realized how much better I felt on lower doses. I just started 12mg a day and already am feeling better...

    Headaches and Brain fog?

    Headaches and Brain fog?

    Hey guys, been on TRT for about 6 months. Started with weekly shots at 150mg up to 180mg which would cause extreme anxiety, never really felt that good. Since then have tried a few different protocols 60 mg every 3.5 and most recently 30 mg EOD with 250mg HCG EOD. No AI. Problem is no matter...

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.
