What are the stages of testosterone?
Testosterone level less than 30 ng/dL – Generally prepubertal (Depending on the laboratory, testosterone levels of 20-30 ng/dL may represent early puberty) Testosterone level of 30-100 ng/dL – Early pubertal. Testosterone level of 100-300 ng/dL – Mid-to-late pubertal. Testosterone level of more than 300 ng/dL – Adult.
What does testosterone do to a man?
Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm. A small amount of circulating testosterone is converted to estradiol, a form of estrogen.
What happens if testosterone is too high?

How do you know if your testosterone is low?
Low testosterone, or low T, is diagnosed when levels fall below 300 nanograms per deciliter (ng/dL). A normal range is typically 300 to 1,000 ng/dL, according to the Food and Drug Administration. A blood test called a serum testosterone test is used to determine your level of circulating testosterone.
When should a man take testosterone?
There’s no magic number for the age at which men should start thinking about hormone therapy.

Testosterone is a steroid from the androstane class containing a ketone and a hydroxyl group at positions three and seventeen respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites. It exerts its action through binding to and activation of the androgen receptor.
What is the mechanism of action of testosterone?
The mechanism of action of testosterone is as an Androgen Receptor Agonist. The chemical classification of testosterone is Androstanes. Therapeutic Testosterone is a synthetic form of the endogenous androgenic steroid testosterone.
What is therapeutic testosterone?
More… Therapeutic Testosterone is a synthetic form of the endogenous androgenic steroid testosterone. In vivo, testosterone is irreversibly converted to dihydrotestosterone (DHT) in target tissues by the enzyme 5-alpha reductase.
How long does it take for serum testosterone to reach steady state?
Serum testosterone concentrations approximate steady-state levels by the end of the initial 24 hours and are at steady state by the second or third day of dosing of the 1% gel.
