What is a testosterone?

-What is it? A hormone, specifically the principal male steroid androgenic hormone.

-How can i tell if I or someone has it? Blood tests ... Total testosterone serum, free/bio available testosterone. LH serum as an additional lab to compare against testosterone levels, which will give a better understanding on how well the HPTA is functioning in conjunction with testicular production (negative feedback loop)

-If someone have high testosterone, what good does he gets?
"High" can subjective in this discussion. The key is to keep this hormone (and others) in balance, where optimal health can be achieved. If you want to know what benefits an individual will get with optimal testosterone levels, then "invest" the time to read through our forum! It's abundant, and definitely more in-depth than a simple answer in a paragraph.

Let us know if you have something specific that is on your plate? Thanks

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.
