What exactly is Anabolic to Androgenic ratio?

Posted by OneStop. Fit on


The anabolic-androgenic ratio refers to synthetically produced variants of naturally occurring male sex hormone testosterone. Anabolic refers to muscle-building activities like increase appetite, bone growth, stimulation of bone marrow causing an increase in the production of RBC. Androgenic refers to the development and maintenance of masculine characteristics like pubertal growth, facial and body hair growth, deepening of the voice, suppression of natural sex hormones, etc. The anabolic-androgenic ratio is an important factor when determining the application of such compounds.

         As far as how this measurement applies to physique athletes and strength training, compounds which retained a high degree of anabolic activity coupled with weak androgenic activity is preferred. Determination of anabolic-androgenic ratio has led to the production and marketing of Sarms which meet all these requirements.

Comparison between the anabolic and androgenic activity of Steroids and Sarms are shown below:

Steroids                                              Sarms

Steroids have equal anabolic              Sarms have high anabolic activity with

and androgenic effects or 1:1              weak androgenic effects or 9: 1 ratio.

e.g. 10 mg of Testa                               e.g. 10 mg Cardarine

        5 mg of anabolic activity:                     9 mg of anabolic activity:

        5 mg of androgenic effects.                 1 mg of androgenic effect.

From the above image, it has shown that the intake of anabolic steroids causes the estrogen level to increase along with the testosterone level. This has led to the appearance of female sexual characteristics as well.

Anabolic activity                                       Androgenic effects

Increase muscle mass                             Increase skin quality

Increased strength                                   Bone density decreases

Increased bone density                            Decreases strength


After using Sarms, preferred anabolic activities is achieved to the maximum without interfering the natural hormones activities.

Anabolic activity                                       Androgenic effects

Increases muscle mass                                     Nil

Increases stamina                                              Nil

Bone density increases                                      Nil

 Due to an increase in Androgenic activity, such side effects occur
