Oxymetholone (also known as anapolon or anadrol) is a very drastic synthetic steroid, 17-alpha-alkylated modification of dihydrotestosterone. It was developed for the treatment of osteoporosis and anaemia, as well as to stimulate muscle gain in malnourished and debilitated patients. Oxymetholone has been approved by the American Food and Drug Administration (FDA) for use in humans. Later there where created non-steroidal drugs that effectively could treat anaemia and osteoporosis; because of this anapolon lost his popularity and by 1993 Syntex decided to cease the production of the drug, as well as other manufacturers did.
Dave, let me clear the air here on some of the confusion… I recommend the 1 vial cycle for someone who is either A. younger or either B. already has high levels of natural testosterone. Now, the typical middle aged male who already had declining levels of natural testosterone COULD go with 500 mg/wk for 10 wks. Recovery is recovery at that point and if you’re going to do it then I see nothing wrong with getting the most out of that first cycle. But what you have to realize is a male with a starting level of high average test levels can still yield the same benefits of someone who is middle range-low end of normal and uses 500mg/wk of test. In either case the person can still gain a solid 20 lbs of muscle from either 1 or 2 vials, the determining factor on this is what they were at to begin with
