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.
It’s all common sense now, certainly I was not going to put myself and my body through the risks of anabolics. I can tell you though, shifting my mind from anabolic steroids simply was not an option for me. However, dealing with it’s side effects is what really held me back from getting any place near this stuff. With my friends’ help in telling about legal steroids, I no longer need to even touch a drop of anabolic steroids. First, I was certainly not going to put my health at risk. Second, I did not want to spend a few years in jail if I ever get busted with this stuff.
our 17 year old cairn terrier has been on Apoquel for 4 mos. the itching, decreased but never stopped. He has been lethargic, urinating more then usual. He has urinated in front of me, also not wanting to stay outside, or even go outside. which is causing more messes to clean up. He has had two seizures which he has never had his whole life. I believe it is the medication that has caused them. He takes mg. tablets, we decreased it to 1/2, he is still having all the symptoms I have described but the seizures started at 1/2 the dose. I am very much convinced Apoquel has caused the seizures.
