The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands .   This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States.   Oxandrolone has also been sold under the brand names Antitriol ( Spain ), Anatrophill ( France ), Lipidex ( Brazil ), Lonavar ( Argentina , Australia , Italy ), Protivar, and Vasorome ( Japan ) among others.     Additional brand names exist for products that are manufactured for the steroid black market. 
On the . black market one of the most popular preparations as of late is the new Boldenon 200 from Ttokkyo. This is the highest dosed version of this steroid ever produced, and is likewise in very high demand right now. This is of course a tremendous improvement over the 25 and 50mg products circulating exclusively just a couple of years ago. Before the Ttokkyo product Denkall had introduced us to the 100mg version of their Ultragan product, which remains a popular and trusted item on the black market today. Ganabol from Middle and South America is also common, and is typical sold in 50 ml vials. However this steroid is also produced in 10, 100, and 250 ml versions. Available in both 25 and 50 mg/ml version, one would look for a large “50” on the label indicating the stronger product. Equi-gan and Maxigan from Mexico are also common as of late, and are acceptable. A 50m1 vial of either usually sells for $250-300 on the black market. Unfortunately the weaker 25mg/ml products are usually very close in price.
Equipoise is not an ideal steroid for the drug tested athlete however. This drug has the tendency to produce detectable metabolites in the urine months after use, a worry most commonly associated with Deca-Durabolin. This is of course due to the high oil solubility of long chain esterified injectable steroids, a property which enables the drug to remain deposited in fatty tissues for extended periods of time. While this will reliably slow the release of steroid into the blood stream, it also allows small residual amounts to remain present in the body far after the initial injection. The release of stubborn stores of hormone would no doubt also be enhanced around contest time, a period when the athlete drastically attempts to mobilize unwanted body fat. If enough were used in the off-season, the athlete may actually fail a drug screen for boldenone although many months may have past since the drug was last injected.
