    New Atrevis Hydrogel Based Testosterone Cream from Empower: Surprising Results!

    @Nelson Vergel have you considered doing something about that Ferritin? Not relevant in your case, but I've seen a study on hypothyroid women who remained symptomatic until ferritin >100. Secondly, have you ever tested your GH or had a GH stimulation test?

    Testosterone gel application sites for maximum DHT

    "Thus, the present study demonstrates that the 5α-reductase activity is mainly located in the apocrine sweat gland and sebaceous gland.

    Testosterone gel application sites for maximum DHT

    Hi all, Wanted to know if anyone knew this. I'm aware that likely genital skin/scrotum is richest in 5a-reductase and thus yields the most DHT from topical testosterone (gel or cream). Does anyone know which site comes after that? From what I've read the sheer amount of skin you apply on...

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.
