Anadrol is an anabolic steroid known for its rapid effects on the body. It would be possible, in just a few days, to see a physical transformation with the right dosage. This effectiveness would be due to the fact that this steroid was originally developed to address the problems of anemia and muscle loss that sometimes occur when suffering from certain diseases like HIV. It increases the number of red blood cells in the body and allows your muscles to swell as quickly as possible by increasing protein synthesis. Anadrol is recognized as one of the most effective anabolic steroids for gaining muscle and especially for not losing this newly acquired muscle mass.
