17α-methylandrost-1,4-dien-17β-ol-3-one

Metandienone (INN) (brand names Averbol, Dianabol, Danabol, Metanabol, Naposim, Vetanabol), or methandienone (BAN), also known as methandrostenolone, as well as 17α-methyl-δ1-testosterone or as 17α-methylandrost-1,4-dien-17β-ol-3-one, is an orally active, synthetic anabolic-androgenic steroid (AAS) and a 17α-methylated derivative of testosterone (specifically, the 17α-methylated derivative of boldenone (Δ1-testosterone)).

 

Metandienone was originally developed in 1957 by CIBA and marketed in Germany and the United States. As the CIBA product Dianabol, metandienone quickly became became the first widely used anabolic-androgenic steroid among professional and amateur athletes, and remains the most common orally-administered steroid for non-medical use.

 

It is currently a controlled substance in the U.S. and UK and remains popular among bodybuilders. Metandienone is readily available without a prescription in certain countries such as Mexico (under the brand name Reforvit-b), and is also manufactured in Asia and many Eastern European countries.

 

Non-Medical Use[edit]

 

Metandienone confiscated by the DEA in 2008.

Bodybuilding

 

It is used by bodybuilders and metandienone continues to be used illegally to this day, typically being combined (stacked) with injectable compounds, such as testosterone propionate, enanthate, cypionate as well as other injectable drugs like trenbolone acetate.

 

Several successful athletes and professional bodybuilders have admitted long-term metandienone use before the drug was banned, including Arnold Schwarzenegger. Other steroids stacked with metandienone are primarily, if not always, injectable compounds such as testosterone, trenbolone and nandrolone. Large doses and long-term use of metandienone have been associated with eccentric left ventricular hypertrophy which presents substantially increased risks of cardiomyopathy if and when the hypertrophy atrophies.[medical citation needed] Athleticism is typically associated with left-ventricular hypertrophy; however, natural athleticism generally presents concentric left ventricular growth which is not linked to an increased risk of cardiomyopathy.

 

Detection of use

 

Metandienone is subject to extensive hepatic biotransformation by a variety of enzymatic pathways. The primary urinary metabolites are detectable for up to 3 days, and a recently discovered hydroxymethyl metabolite is found in urine for up to 19 days after a single 5 mg oral dose. Several of the metabolites are unique to metandienone. Methods for detection in urine specimens usually involve gas chromatography-mass spectrometry.
