Testosterone
"I tried Testim samples and found its fragrance revolting and it did not dissipate through the day.  I cannot imagine smelling as if I applied cologne every day of my life.  And I really ripped into the manufacturer's stupidity on their website.  One thing any man with hypogonadism wants is for no one but his doctor and lover to know he has hypogonadism.  Walking around with the same strong scent everyday would be odd in an office environment and no doubt someone would ask what the cologne name is.  It is so thoughtless."
