It makes sense that Androgel would rub off on the shirt, thus ineffectively delivering therapeutic androgen levels. It's like putting rubbing alcohol on the skin and hoping for a buzz. To achieve therapeutic levels on Androgel, it must be left on the skin for 5-6 hours, and you still aren't guaranteed the most from your course of treatment because most of the T is dried on top of the skin and never even has the chance to be delivered through the skin surface. You shoud probably consider Testim 1% gel. Within 2 hours therapeutic levels are achived at mid-high normal ranges. And showering, swimming, and sweating, become non-issue after that 2 hour window because it's all in. This information is in Testim's clinical insert in so many words. Dad says it's a wonder drug. His initial bloodwork -150ng/dl. His endocrinologist tried him on 1 small tube of Testim per day and his level after 2 months- 650ng/dl!!! Dad works his tail off every day doing construction with no AC. He constantly sweats. So he made a good decision to be on Testim- cheaper too. It shoots the medicine through the skin before the hottest part of the day when he sweats gallons of fluid. He does his 90 second rubbing routine each morning and washes his hands before his coffee. He swings a hammer with a smile as opposed to barking orders with an attitude. a changed man.
