    Would you happen to know if the DHT test on discountedlabs is the Equi dialysis? It doesn't say. Is there even a test for HCG and since i'm not even on HCG would this test be irrelevant?

    27 Yr Male on TRT, Zero Libido

    Thanks for your reply, shouldn’t E2 raise with a subsequent rise in testosterone as what was seen, a nearly double increase in test with a small decrease in E2, this makes no sense. Doesn’t high and low E2 have the same symptoms? So basically get E2 retested with the LC/MS/MS method whatever...

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.
