Partly this is due to its apparent lack of non-AR-mediated activity. This can be corrected of course by stacking with a Class II steroid such as dianabol, anadrol, 4-AD, or nor-4-AD: the latter two steroids require high blood levels which are not obtained by oral use of the powders.
The other part of the reason for this is that bodybuilders make unfortunate and unreasonable comparisons when judging anabolic steroids. If say 8 tablets per day does little, then the drug is pronounced useless or weak by the user. But that is only 20 mg/day, or 140 mg/week. Does 140 mg/week testosterone give much results? No. Few anabolic steroids give dramatic results at that dose. Per milligram the potency is reasonable, but each individual tablet is weak because the dosage is small.

Because of its high price, very few bodybuilders have taken large doses of oxandrolone. There is a single case in the medical literature (Forbes et al.) where it is reported that a competitive athlete self-administered 150 mg oxandrolone per day with remarkable gains. This is of uncertain credibility because unless urinalysis was done to verify that no other steroids were taken, there is no way to be certain that the athlete did not actually take more drugs than he reported. In any case, at current prices, only the quite wealthy could afford such a dose. I personally have tried 150 mg/day and considered it somewhat effective, but not dramatically so, and not a preferred regimen.

Oxandrolone does not aromatize or convert to DHT, and has a longer half life than Dianabol - 8 hours vs. 4 hours. Thus, a moderate dose taken in the morning is largely out of the system by night, yet supplies reasonable levels of androgen during the day and early evening.

Oxandrolone shares the liver toxicity problems common to 17-alkylated steroids. At one time it was thought that it did not, but both clinical and practical experience with Oxandrin has shown that at doses of 40 mg/day and higher, liver toxicity is indeed an issue with prolonged use.

Primobolan, I believe, should be considered a superior compound, offering the same activity at (usually) a lower price and without the alkylated-toxicity issue.

Effective Dose: 5 - 15 mg per day

Anavar (Oxandrolone)

Common uses and directions for Anavar, oxandrolone
Oxandrolone has often been used as a growth-promoting agent in the therapy of boys with growth delays in adolescence. Oxandrolone is also used in treating girls affected with Turner's syndrome, another growth-delay ailment. In obese individuals, oral oxandrolone has been shown to decrease subcutaneous abdominal fat more than Testosterone enanthate or weight loss alone, and it also tended to produce favorable changes in visceral fat.
Athletes like oxandrolone for three reasons. First, oxandrolone causes a strong strength gain by stimulating the phosphocreatine synthesis in the muscle cell without depositing water in the joints and the muscles.

Secondly, oxandrolone is one of the very few steroids that does not aromatize into estrogen, at any dosage, which has various advantages for the athlete.

The third reason for the popularity of Anavar is that oxandrolone does not influence the body's own testosterone production.

A suitable dosage of Anavar for a male athlete is 0.125 mg./pound of body weight per day. Women should not take more than about half of that dosage, though. Anavar is normally taken two to three times daily after meals thus assuring an optimal absorption of the oxandrolone.

Oxandrolone can give gastrointestinal problems ranging from a sensation of stomach fullness to appetite suppression, nausea, and diarrhea.

Athletes like oxandrolone for three reasons. First, oxandrolone causes a strong strength gain by stimulating the phosphocreatine synthesis in the muscle cell without depositing water in the joints and the muscles.

Secondly, oxandrolone is one of the very few steroids that does not aromatize into estrogen, at any dosage, which has various advantages for the athlete.

The third reason for the popularity of Anavar is that oxandrolone does not influence the body's own testosterone production. This special feature of Anavar can be explained by the fact that the oxandrolone is not converted into estrogen.

Oxandrolone causes very light virilization symptoms, if at all. This characteristic makes Anavar a favored remedy for female athletes since, at a daily dose of 10-15 mg., masculinizing symptoms are observed only rarely.

Directions

Anavar should be taken two to three times daily after meals thus assuring an optimal absorption of the oxandrolone. Common dosage is 8-12 tablets in men and 5-6 tablets in women. The rule of thumb to take 0.125 mg./pound of body weight daily has proven successful in clinical tests.

Anavar can be combined with almost any other steroid such as Winstrol , Deca durabolin, Dianabol , or Anadrol .

If you miss a dose, take it as soon as remembered if it is within an hour or so. If you do not remember until later, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.

Precautions

Since oxandrolone is only slightly toxic and usually shows few side effects, several athletes use it over a prolonged period of time. However Anavar should not be taken for several consecutive months, since, as with almost all oral steroids it is 1 7-alpha alkylated and thus liver toxic.

Possible side effects

Overdose
