Conditions:

Stanozolol is a synthetic anabolic steroid derived from dihydrotestosterone. It is indicated prophylactically to decrease the frequency and severity of attacks of angioedema. In rare cases, serious and even fatal cases of liver problems have developed during treatment with stanozolol. Anabolic steroids may increase sensitivity to anticoagulants; therefore, dosage of an anticoagulant may have to be decreased in order to maintain the prothrombin time at the desired therapeutic level.

Mestanolone is an oral analogue of dihydrotestosterone. This steroid is a 17-alpha methylated form of this potent endogenous androgen, being essentially (in structure) to dihydrotestosterone what methyltestosterone is to testosterone. Overall, mestanolone has an activity profile not very dissimilar from the hormone it is derived from. Like dihydrotestosterone, mestanolone is primarily androgenic in nature, displaying a low level of anabolic activity. Both dihydrotestosterone and mestanolone are also devoid of estrogenic activity. Dihydrotestosterone was synthesized in 1935. After that 17-alpha-methylated version also appeared. This steroid was not frequently used in clinical medicine. It was produced under the name of ermalon for short period of time. Most studies involving mestanolone were carried out in the 1950s and 1960s. In the 1970s and 1980s it was used as part of the East German doping machine. Mestanolone was evaluated not for its anabolic ability but for its androgenic essence. It improved the functioning of the CNS and neuromuscular interaction. Athletes claimed that it did not make them huge, but gave them speed, strength, aggression, stamina and resistance to stress. Mestanolone is still valued as an oral androgen.

Conditions:

Oxymetholone (17beta-hydroxy-2-[hydroxymethylene]-17-methyl-5alpha-androstan-3-one) is a 17alpha-alkylated anabolic-androgenic steroid and a synthetic derivative of testosterone. It has been approved by the US Food and Drug Administration for the treatment of anemias caused by deficient red cell production. Acquired aplastic anemia, congenital aplastic anemia, myelofibrosis and the hypoplastic anemias due to the administration of myelotoxic drugs often respond. Drug interactions exist with cimetidine, paroxetine, and haloperidol, but are not expected with indinavir, ritonavir, clarithromycin, or itraconazole.
