Testosterone is converted to dihydrotesterone → effects genitals
Testosterone is converted to estradiol → effects bone, sexual function, fat
Testosterone is unconverted → effects muscle mass

BENEFITS:

Increased energy, increased muscle mass, improvement in sexual function (ie libido and erectile function), improved sleep, improved moods

RISKS:

Testosterone at chronically elevated levels (> 1100 ng/dL) increase risk for cardiovascular disease (ie heart attack and stroke), erythrocytosis (too many red blood cells), blood clots, elevated cholesterol (triglycerides), lower HDL, testicular shrinkage, gynecomastia

HOW TO GET IT:

Testosterone replacement can be administered orally (least effective), topically, intramuscularly (injection) or intranasally (still in research)
