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).
