It is interesting to note that oxymetholone does exhibit some tendency to convert to dihydrotestosterone in the body, although this does not occur via the 5-alpha reductase enzyme. Oxymetholone is already a dihydrotestosterone-based steroid, so no such alteration can take place. Aside from the added c-17 alpha alkylation (discussed below), oxymetholone differs from DHT only by the addition of a 2-hydroxymethylene group. This grouping can be removed metabolically, reducing oxymetholone to the potent androgen 17alpha-methyl dihydrotestosterone (mestanolone). 387 There is little doubt that this biotransformation contributes at least on some level to the androgenic nature of this steroid. Note that since 5-alpha reductase is not involved, the relative androgenicity of oxymetholone is not affected by the concurrent use of finasteride or dutasteride.
Oxymetholone for women: what a lady athlete should know about it.
In conclusion one can safely state that the negative effects on the system associated with the use of this hormone are rather drastic and that the use is therefore not recommended for beginners, women or people who have pre-existing afflictions. Nonetheless Anadrol remains a popular steroid among experienced users to kick-start a steroid cycle because of its magnificent increases in strength and size. Most people who have used oxymetholone with great success have no problem calling it the strongest and most reliable steroid available today. A somewhat surprising remark however, since Methandrostenolone can produce similar results with half or a third of the doses normally used with oxymetholone and with less side-effects. So personally I would recommend methandrostenolone over oxymethelone, as its clearly stronger, milligram fro milligram. Oxymetholone remains a strong and favorable compound however, despite its side-effects. Its effects may also be slightly more explosive than those of methandrostenolone and therefore people seeking strength may give it an edge over the former.
The common side effects of oxymetholone include depression , lethargy , headache , swelling , rapid weight gain , priapism , changes in skin color, urination problems, nausea , vomiting , stomach pain (if taken on an empty stomach), loss of appetite , jaundice , breast swelling in men, feeling restless or excited, insomnia , and diarrhea .  In women, side effects also include acne , changes in menstrual periods , voice deepening , hair growth on the chin or chest , pattern hair loss , enlarged clitoris , and changes in sex drive .   Because of its 17α-alkylated structure, oxymetholone is hepatotoxic .  Long term use of the drug can cause a variety of serious ailments, including hepatitis , liver cancer , and cirrhosis ; therefore periodic liver function tests are recommended for those taking oxymetholone.
