Anadroxyl (Oxymetholone)

Anadroxyl (Oxymetholone) is a potent oral anabolic steroid derived from dihydrotestosterone. More specifically, it is a close cousin of methyldihydrotestosterone (mestanolone), differing only by the addition of a 2- hydroxymethylene group. This creates a steroid with considerably different activity than mestanolone, however, such that it is very difficult to draw comparisons between the two. For starters, oxymetholone is a very potent anabolic hormone. Dihydrotestosterone and mestanolone are both very weak in this regard, owing to the fact that these molecules are not very stable in the high enzyme (3- alpha hydroxysteroid dehydrogenase) environment of muscle tissue. Oxymetholone remains highly active here instead, as is reported in standard animal assay tests demonstrating a significantly higher anabolic activity than testosterone or methyltestosterone. Such assays suggest the androgenicity of oxymetholone is also very low (1/4th to 1/7th its anabolic activity), although real world results in humans suggest it is decidedly higher than that. Oxymetholone is considered by many to be the most powerful steroid commercially available. A steroid novice experimenting with this agent is likely to gain 20 to 30 pounds of massive bulk, and it can often be accomplished within 6 weeks of use. This steroid produces a lot of water retention, so a good portion of this gain is going to be water weight. This is often of little consequence to the user, who may be feeling very big and strong while taking oxymetholone. Although the smooth look that results from water retention is often not attractive, it can aid quite a bit to the level of size and strength gained. The muscle is fuller, will contract better, and is provided a level of protection in the form of extra water held into and around connective tissues. This will allow for more elasticity, and will hopefully decrease the chance for injury when lifting heavy. It should be noted, however, that a very rapid gain in mass might also place too much stress on your connective tissues. The tearing of pectoral and biceps tissue is commonly associated with heavy lifting while massing up on steroids, and oxymetholone is a common offender. There can be such a thing as gaining too fast.

Administration (Men):

Early prescribing guidelines for oxymetholone recommended a dosage of 2.5 mg three times per day to reverse the wasting process and provide lean body mass gain. Doses as high as 30 mg were employed in some cases. Current prescribing guidelines recommend a dosage of 1-5 mg per kilogram of bodyweight per day for treating anemia, although indicate that a dose of 1-2 mg/kg is typically sufficient. A 175-pound person would take approximately 150 mg per day at the 2 mg/kg dosage level. In some other countries, it is recommended to limit the dosing of oxymetholone to 100 mg per day. Therapy is usually given for a minimum of three to six months. When used for physique- or performance-enhancing purposes, an effective oral daily dosage would fall in the range of 25-150 mg, taken in cycles lasting no more than 6-8 weeks to minimize hepatotoxicity. This level is sufficient for dramatic increases in muscle mass and strength. Higher doses are rarely administered due to the strong estrogenic nature of the drug, as well as the high potential for hepatotoxicity.

Administration (Women):

Prescribing information for oxymetholone in the U.S. makes no distinction with the dose for females. Oxymetholone is generally not recommended for women for physique- or performance-enhancing purposes due to its very strong nature and tendency to produce virilizing side effects.
