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.

On the black market Deca remains one of the most popular anabolics in circulation. Currently 200mg/ml preparations from Mexico are dominating the marketplace, and due to their high availability and lower cost are minimizing the appearance of lower dosed compounds. For example, in addition to Norandren 200 Brovel also makes Norandren 50 (a 50 mg/ml version of this steroid), but it is almost unseen right now. I should point out that their 50m1 vial of Norandren 200 is also the largest container of nandrolone to be found in such strength, and represents one of the best values anywhere for this steroid. We can see why it is much more desired right now. Also common are Nandrolona 200 from Tornel and Decanandrolen from Denkall, both in 1 Oml vials. In an effort to provide more innovative, conspicuous and cost-effective products, the Mexican firm Ttokkyo has recently topped its competitors and released Nandrolona 300. This is a 300mg/ml preparation of nandrolone decanoate, which is by far the highest dose of this compound ever to be produced commercially. To spite the defiant opinions of many, indeed this is a legitimate product. I have not experimented with the solubility of nandrolone decanoate myself, but do know that this particular ester is highly fat-soluble. Reaching 300mg in a milliliter of oil does not seem like an unreasonable or impossible task, and I would guess requires at best some minor tweaking of alcohol levels (perhaps none at all).
