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. 
Hi, I just bought your book, and I’m very excited to get started. I’ve always wanted to be in “good shape,” lean and tone, but have never been able to get rid of jiggle. I’m curvy at 5’3″ and 132 pounds, and getting rid of fat in place of muscle is what I’m looking to do. I’ve always tried to remain active, even when I can’t go to the gym on a regular basis. For the past few weeks I’ve been working out twice a day, with heavy cardio and mild weight training in the morning, and interval circuit training in the evening while also doing a heavy HEAVY cut back on calories. I lost weight in my first week, but after that, it kind of just stuck near 132 and hovered. I’m much more concerned with my appearance than the number on the scale (though that doesn’t hurt either). I’m a little nervous that going from eating so few calories to what you recommend might cause a temporary fat gain. Also, I have a very busy schedule, but I make the time to make my own lunches and snacks to bring to work so that I can stay on track with whatever program I’m doing. Is there a meal plan provided in the book or just guidance tips to create your own? The book comes tomorrow, but I’m excited to get started and want to make sure I have all the tools I need to do so.
