The use of oxymetholone should be strict and brief. While it is no doubt the strongest steroid, quantitatively, its also by far the most hazardous steroid to your health. Apart from the great risk of common steroid-related side-effects (acne vulgaris, benign prostate hypertrophy, gynocomastia and androgenetic alopecia), it also has numerous other side-effects. Most notable is oxymetholone's hepatoxicity (damaging to the liver) : Its standard 17-alpha-alkylated as with most oral steroids, resulting in an inavoidable raise in liver transaminase enzyme counts. The most frequent of the hepatoxic effects is jaundice4 (yellow coloration of the skin) due to an oxymetholone induced increase in biliburine, but others include peliosis hepatis and formation of hepatic tumors (cancer). And that's not all. There is also a number of intrinsic side-effects noted with the use of this steroid. Headaches, stomach aches, nausea, vomiting, insomnia and diarrhea are among common afflictions associated with oxymetholone use.
This is the reason why only strict doses of oxymetholone are used , often only 1-2 tabs of 50 mg. The general rule of thumb is to use 0.5 or 0.6 mg per pound of bodyweight, most likely putting you in the 100-150 mg range. Because of the negative effects on the liver, its often not used for more than a two or three weeks. The results are fast, but also fleeting and therapy is usually continued with another aromatizable compound, most likely a long acting testosterone like Sustanon or testosterone enanthate. The Anabolic Review also warns that under no circumstances should oxymetholone use exceed 6 weeks. When using oxymetholone, or any oral 17-alpha-alkylated steroid for that matter, one should always consult a physician on a frequent basis and get your liver values checked. Its not that oxymetholone is necessarily more toxic to the liver, but rather that much higher doses are needed than with other oral steroids, so the relative risk increases as well.
