Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
I’m just shy of age 71. I’ve always had a high sex drive, still do. I’ve only had two T tests, three years ago, 260, recently, 290. I don’t know if that was normal variation, or due to progesterone cream applications over the last few years. My Medicare insurer turned down a prescription the urologist wanted for Androgel. To help with weight loss. Despite those T numbers, I’m still randy as hell, and despite my alcohol consumption, my balls are still huge per internet sources. And many lovers over the years. (The urologist didn’t say anything was wrong.) The other morning I woke up with wood, walked out to the patio, and urinated a strong stream with a dick curving heavenward.
Steroids can also increase the process of male baldness specifically in predisposed users. Because the natural testosterone of human body is not required when anabolic steroids are used, the body halts generating its own testosterone supply which results in testicles shrinking. Abuse of steroids can result in the significant rise of blood pressure due to their overall ability to increase red blood cell count. The steroids users are more exposed to ‘Roid Rage’ or increased aggression. Evidence suggests that abuse of anabolic steroids significantly increase aggressive and violent behavior among some users.
