    Joined Defy Medical-- Does this treatment protocol make sense?

    At Nelson's suggestion I had my consultation with Dr Saya over the phone about a week ago. He went over my labwork. My total t came in at 343 on a range of 348-1197. I'm 35 y/o. I basically have all the classic symptoms of low t-- no libido, low energy, depression, no morning wood, increased...

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.
