Oxymetholone was the U.S. brand name for 50mg Oxymetholone tablets, which were available in the U.S. until 1993. Syntex is the world producer of this drug, and markets it under a few different brand names in other areas. Oxymetholone is a 17alpha alkylated oral steroid. Second to none, this product is generally considered the most powerful steroid available. Oxymetholone will produce extremely dramatic weight and strength gains in its user. Some of this weight and strength gain will be due to the drugs heavy water retention. Users of Oxymetholone report severe crashes when stopping usage, mostly due to the loss of water and inhibited endogenous hormone production brought about during the cycle. Aside from the water, Oxymetholone will pack on the mass like no other steroid. A short cycle of Oxymetholone could account for a gain of over 20lbs in many users, sometimes more. As this drugs anabolic properties are so extreme, so are it's androgenic side effects. Due to the strength of these side effects, Oxymetholone should never be used by women. For starters, oxymetholone will easily convert to estrogen and DHT. As stated earlier water retention will be present, along with an increase in blood pressure. Kidney functions may also need to be looked after during longer use. Hair loss has also been reported among users with a predisposition for male-pattern baldness. The most dangerous attribute of Oxymetholone is that is it 17alpha alkylated. As you probably know 17aa orals are toxic to the liver. 

Unlike Dianabol (another popular 17aa oral) which is effective in doses of as little as 15mg, Oxymetholone users generally start with 50mg/day and often lead up to 150mg/day. So when a user takes 3 Oxymetholone tablets, his liver is processing roughly the equivalent of 30 Dianabol tablets. This obviously is quite a lot of 17aa steroid for your liver to process, so it is pertinent a user has his liver enzymes checked regularly with a doctor. When you hear of horror stories involving liver cancer from steroid use, Oxymetholone is most often the culprit. For medical treatment, Syntex recommends 1-5mg/kg of bodyweight per day. This leads many patients to take as many as 8+ tabs per day, for extended periods of time. This is much more than an athlete would need and should be using, which may be why documented cases of liver cancer seem more prominent among non-athletes taking Oxymetholone medically. Lately, many people are speculating on how long this product will be available worldwide. Syntex has stopped production of Oxymetholone in the U.S., Oxitosona in Spain and medical use in other areas of the world seems to be declining due to the advent of newer drugs to treat conditions in which Oxymetholone was formerly used. 

All forms of Oxymetholone are now being counterfeited, often with incredible accuracy. In the U.S., a version of the now unavailable American Oxymetholone has been found in which box, bottle and even the stamping of the tablet are identical to the real version. The only seen difference is the lack of active ingredient. Since real U.S. Oxymetholone has been out of production for some time, it would be safe to say anything labeled Oxymetholone is fake. Anapolon is copied as well with good accuracy. Oxitosona was/is counterfeited but since Syntex dropped its production in 1993, all forms should be considered fake. Hemogenin from Brazil is another popular version, which makes its way to the states and is also counterfeited.
