Priority: Regardless of the purpose of use, all those who supplement with Anavar will find their rate of recovery is enhanced, as well as their muscular endurance. The individual will not tire out as fast, and he will be able to push longer and harder. This does not mean we should increase the duration of our training sessions, which may or may not be the case depending on the situation. However, we will make better use of each training session, we will make better use of our time on the field and all in all more quality work will be done.
Corticosteroids have been used as drug treatment for some time. Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a complicated 36-step process that started with deoxycholic acid, which was extracted from ox bile .  The low efficiency of converting deoxycholic acid into cortisone led to a cost of US $200 per gram. Russell Marker , at Syntex , discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams . His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception .  In 1952, . Peterson and . Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone.  The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US $6 per gram, falling to $ per gram by 1980. Percy Julian's research also aided progress in the field.  The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.
So, we see that steroid hormones control many vital functions in your body. Of course, we wouldn't have these or any steroids if we did not have cholesterol. It could be said that the most important steroid molecule in your body is cholesterol , because cholesterol is the parent compound from which steroids are derived. It is basically the precursor for steroid hormones and other steroids. We see by looking at the structure of cholesterol that it is a steroid, because it has the four rings of carbon atoms. Attached to the rings we see a hydrocarbon tail and a hydroxyl group . Cholesterol is a 27-carbon steroid and has a molecular formula of C27H45OH.
