Furazabol
Encyclopedia
Furazabol is a derivative of the anabolic steroid
stanozolol
. It differs from stanozolol by having a furazan ring system in place of the pyrazole
. It has a c-17alpha methyl group, which allows it to be taken oral
ly and causes hepatotoxicity
in some individuals.
According to William Llewellyn, author of Anabolics 2007, the cholesterol-lowering effects of furazabol are a myth. In the 1970s, research studies showed that furazabol along with many other orally-active AAS like Anavar (oxandrolone) lowered total serum cholesterol. It was subsequently established that the cholesterol reduction from oral AAS was the result of suppressed HDL levels. As such, it would be expected that furazabol, like other oral anabolic steroids, while reducing total cholesterol levels would still adversely affect the HDL/LDL ratio and increase the risk of cardiovascular disease.
The Canadian sprinter Ben Johnson tested positive for stanozolol after winning the gold medal in the 100 meter sprint at the 1988 Summer Olympics. His doctor, Dr. Jamie Astaphan, maintains that his urine sample was sabotaged because Johnson was administered furazabol, which was not an IOC banned substance at the time. Subsequently, training partner and fellow Charlie Francis athlete Angela Issajenko (Taylor), in her book "Running Risks" outlined a theory stating Ben Johnson actually was using stanozolol. She substantiated this by stating that her supply of what she thought was furazabol was retested following the Dubin Inquiry and was found to be stanozolol, explaining the positive test.
Anabolic steroid
Anabolic steroids, technically known as anabolic-androgen steroids or colloquially simply as "steroids", are drugs that mimic the effects of testosterone and dihydrotestosterone in the body. They increase protein synthesis within cells, which results in the buildup of cellular tissue ,...

Hepatotoxicity
Hepatotoxicity implies chemical-driven liver damage.The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents. Certain medicinal agents, when taken in overdoses and sometimes even when introduced within therapeutic ranges, may injure...
