It has weak androgenic effects, i.e. it causes very strong gains in strength but without excessive weight gain because it produces almost no water retention in the body. Oxandrolone itself does not cause a qualitatively significant change in muscle mass. However, according to recent studies, the mass gained is maintained in the long term. It does not aromatize even with higher and longer-term use. This substance does not affect endogenous testosterone production at short-term and low use. With long-term use, however, testicular atrophy is common. (A study showed that for 12 weeks, taking 80mg daily suppressed endogenous testosterone production by 67%).

Oxandrolone is a very popular steroid. The Searle company introduced it to the US market under the name Anavar in 1964. Oxandrolone enjoyed great popularity for two decades until its production was discontinued (June 1, 1989). Today, oxandrolone is legally produced only in a few countries, and only in the form of tablets with a very low content of the active substance.

Structurally, it is a 17-alkylated derivative of DHT, which is unique among steroids by the substitution (replacement) of the 2nd carbon on the A-ring by oxygen (O). This minor chemical change prevents flavoring and overall makes oxandrolone one of the least androgenic steroids with minimal side effects.

Side effects:

Side effects compared to other substances are quite a bit weaker, acne is most commonly mentioned and it has quite a strong effect on the digestive tract (at higher doses), thus regular diarrhea is often mentioned when taking oxandrolone. As one of the few steroids it promotes the multiplication of muscle myofibrils, especially with long cycles of around 2-3 months. It is Particularly suitable for the second half of the cycle, but can also be used for the whole. Efficacy on positive nitrogen balance is even in minimal amounts. It promotes the formation of creatine phosphate and increases its storage in the muscle. It is especially suitable for dieting, but also for volume. It suppresses the feeling of hunger and, according to the latest studies, it also has mild fat-burning effects. It is a 17-alpha alkylated preparation, so it is toxic to the liver, but it is not extreme (studies where oxandrolone was given every day at 20mg for 12 weeks saw minimal effect on increasing liver values).

Because oxandrolone is a derivative of dihydrotestosterone, it does not aromatize at all and thus does not cause a soft muscular appearance, a worn down look or gynecomastia in men. Also, androgenic effects are minimal, even in sensitive individuals. It can be said that in normal doses, oxandrolone has virtually no visible side effects. Because it does not produce sudden muscle gains, it is suitable for users with a potential risk of higher blood pressure. Oxandrolone can sometimes cause bloating and vomiting if taken with food. Some users also report nausea if they take oxandrolone alone.

The use of this weak androgen is quite widespread in women. Almost no signs of masculinization have been observed in women taking 5 mg of oxandrolone daily. Most women start on one tablet a day and increase the dose up to 3 tablets. A dose of 5 mg has been shown to be optimal. The first signs of virilization are increased pubic hair, thickening of the voice, acne, decreased libido or enlargement of the clitoris. If any of these symptoms occur, women should stop taking oxandrolone immediately.

It is often stated that oxandrolone even in high doses does not cause suppression of natural androgen levels, however this information is not based on truth. Like any steroid, it reduces the body’s testosterone levels, albeit to a lesser extent than other steroids. Twelve weeks on 20-40 mg/day can lead to about a 45% reduction in body testosterone. Taking 80 mg/day for the same period of time dropped body testosterone by 66%!

Anabolic effects:

Oxandrolone is not good for bulking, rather for strength and muscle hardness as it promotes myofibrillar hypertrophy and stimulates creatine phosphate stores. Some powerlifters claim that it is the number 1 steroid for gaining strength without weight gain and excessive water retention. The development of muscle mass progresses slowly, but it is high quality muscle. Oxandrolone is therefore widely used by powerlifters who want to increase strength but stay in their weight category. It is also a good choice for when drawing when the purpose is not to put on weight. It is appreciated as a very good “fat burner”. It is often possible to see several bodybuilders taking oxandrolone two months before a competition. It is also recommended for conditions of catabolism or loss of active body mass related to AIDS, cancer, osteoporosis and hepatitis.

The views on the anabolic effects of oxandrolone are influenced by its low concentration in tablets and its high price, which makes it difficult to take high doses. Athletes often take only about 20 mg per day, which is very low compared to doses with other steroids. For sufficient effect, however, 40-80 mg/day is recommended.
