Alpha Oxydrolone

Oxydrolone is most likely second only to Dianabol (methandrostenolone) as a bodybuilding anabolic steroid. Additionally, it has had considerable medical importance particularly for treatment of anemia, and more recently to help maintain lean body mass in HIV-compromised patients. While many have the subjective opinion that Anadrol is a harsh drug in terms of side effects, medical findings and the findings of many athletes are quite different.
Stacking Anadrol with Other Steroids

An interesting further question concerns combination of Anadrol with other anabolic steroids. For exmaple, adding Anadrol to 50 mg/day of Dianabol gives little added benefit to a steroid cycle; in contrast, adding Anadrol to 50-100 mg/day trenbolone acetate or 60-80 mg/day Anavar (oxandrolone) gives dramatic improvement. In this its stacking behavior is similar to that of Dianabol, but not to that of trenbolone. Likely this is because unlike trenbolone, oxymetholone does not bind strongly to the androgen receptor, and most of its anabolic effect is likely not genomically mediated via the AR.
Anadrol Side Effects

With regard to harsh side effects sometimes perceived in bodybuilding, this principally or only occurs when estrogen levels are elevated. While oxymetholone does not itself aromatize and does not have estrogenic activity, it may be that it can interfere with estrogen metabolism. Whether that it is the cause of the problem or not, keeping estradiol levels under control keeps Anadrol similar in side effects to other oral anabolic steroids. Estradiol levels may be kept under control either by using an aromatase inhibitor such as letrozole or Arimidex, or by limiting use of aromatizing steroids such as testosterone.
