Description:
Anavar was the old U.S. brand name for the oral steroid oxandrolone, first produced in 1964 by the drug manufacturer Searle. It was designed as an extremely mild anabolic, one that could even be safely used as a growth stimulant in children.
One immediately thinks of the standard worry, "steroids will stunt growth". But it is actually the excess estrogen produced by most steroids that is the culprit, just as it is the reason why women stop growing sooner and have a shorter average stature than men.
Oxandrolone will not aromatize, and therefore the anabolic effect of the compound can actually promote linear growth. Women usually tolerate this drug well at low doses, and at one time it was prescribed for the treatment of osteoporosis.
As the opinions surrounding steroids began to change in the 1980′s, prescriptions for oxandrolone began to drop. Lagging sales probably led Searle to discontinue manufacture in 1989, and it had vanished from U.S. pharmacies until recently. Oxandrolone tablets are again available inside the U.S. by BTG, bearing the new brand name Oxandrin. BTG purchased rights to the drug from Searle and it is now manufactured for the new purpose of treating HIVAIDS related wasting syndrome.
Anavar is a mild anabolic with low androgenic activity. Its reduced androgenic activity is due to the fact that it is a derivative of dihydrotestosterone (DHT).
