Anadrol is an oral steroid that was first developed in the 1960s to treat muscle wasting diseases and anemia. This potent steroid is well known for how quickly it can increase size and strength. Estrogen levels can climb considerably with the use of anadrol, making water retention and gyno major problems. Since much of the weight gained while taking anadrol is in fact water retention, much of it can expected to be lost once use is discontinued. Anadrol use is much more common than the other drugs discussed here. As with cheque drops and halotestin, anadrol is a 17aa oral steroid. Like all steroids in this category, anadrol is liver toxic. Liver enzymes increase dramatically with the use of anadrol. This steroid may not be as liver toxic as cheque drops or halotestin, but its ability to cause damage is a concern. Liver enzymes appear to return to normal when it is used for only 4-6 weeks and use is stopped. When anadrol is used at doses above 100mg a day or for extended periods of time, the potential for permanent liver damage does exist. The dangers of this steroid increase when it is combined with other oral steroids and/or alcohol.
