Steroid Guide Review

Androgel & Androderm

(testosterone)

Transdermal Testosterone has been marketed heavily in the Hormone Replacement Therapy Market for the last decade. For over 50 years, testosterone therapy has been used for the treatment of hypogonadism. In recent years, there has been an increase in the use of testosterone therapy for men with late-onset hypogonadism, sometimes referred to as andropause. Testosterone therapy in older and hypogonadic men can significantly improve their sense of well-being, and lead to increases in muscle and bone mass, upper body strength, virility and libido (5). Oral delivery of unmodified testosterone is not really a viable option, due to it´s rapid first-pass metabolism, possible liver toxicity, and its relatively short half-life.

Thus, injectable testosterone was used for a very long time as an effective hormone replacement method. Roughly a decade ago, alternatives to injectable and oral testosterone were developed. Originally, these alternative methods of application for testosterone meant shaving an area of the skins surface (*usually the scrotum… no, really) and attaching a testosterone patch with low, dry heat (again, no, really) like a hairdryer, which basically hot-glued the testosterone patch to the scrotum.

I can´t see, for the life of me, the logic employed by the doctor who thought this method was preferable to weekly or twice-monthly injections. Luckily, this painful procedure progressed to the point where it´s at now, and you can simply apply a self sticking patch or rub some testosterone gel anywhere on your body, and get the same effect. Recently, the BALCO scandal featured many references to the gel method. I think, for an adequate understanding of these types of products, we´re going to have to take a look at both the drug (testosterone) as well as the method of administration (transdermal delivery), and see how they work together, and how they compare with testosterone injections.

When some (nonscrotal) transdermal testosterone preparations have been examined, they showed that the plasma concentration of TS increased very rapidly, and reached the peak level within 3-6 hours of application of the experimental patch..(2) This is comparable with some of the better oral products out there, in my experience, an athlete would usually swallow a pill than have a patch hanging on them for a day, though.

Basically, you can expect all of the benefits of injectable testosterone with the transdermals (if the mg doses were the same, which they are not). What we´re dealing with here is Androderm, which is a patch containing 12.2mgs of testosterone, and androgel, which gives you about the same (you only get 10% of the total drug contained in the preparation… thus a hundred mgs of test in a gel form, would yield a 10mg amount in your body).
