I recall when I was first diagnosed with asthmatic bronchitis, I had pneumonia and didn’t know it, made a regular clinic appointment for what I assumed was just my normal bronchitis, and my 02 was like 78. I walked into the room and the nurse took one look at me, left the room to get the pulse ox, came back and measured it. Got that level, and went to get the oxygen tank. I was actually terrified. I had noticed I was out of breath a lot, and that I needed to sit down after walking across the room or up the stairs, etc. But I didn’t think it was that bad! They also nebbed me that visit.
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.
