Application:Andarine is a brand of selective androgen receptor modulator (SARM). The full name is S-40503 but called S-4 for short. The product was manufactured by Kaken Pharmaceuticals, a Japanese pharmaceutical company, for the treatment of osteoporosis. SARM comes in different versions with the stronger version called Andarine and it happens to be my favorite of all SARMS in the market today.

How Does Andarine work?

Andarine binds incredibly well to the androgen receptors of bone and muscle. While it doesn't tend to impress in terms of building pounds upon pounds of muscle like trenbolone will, it has amazing effects on fat loss. Why? Andarine is the least anabolic, yet most androgenic of the SARMS. When androgenic hormones or sarms attach to the androgen receptors in your adipose tissue or fat (yes we have androgen receptors in our fat too) they trigger fat oxidation.

This SARM is selective and shows no noticeable prostate activity. Andarine proved to be poor at building muscle tissue at lower doses, but it did, in fact, build lean hard muscle tissue at higher doses. These tissue gains have often been compared to that of winstrol or anavar, but, of course, without the associated androgenic side effects. Andarine is especially outstanding at strengthening, preserving and even building bone mass.

Very minimal growth on secondary sexual organs such as the prostate.
The LDL/ HDL ratio is not affected which makes it a low cardiovascular risk.
0% chance of aromatization, male breast lactation, or rise in any other female characteristic during the post cycle recovery.
Testosterone is not diminished in any capacity during the post cycle recovery.
Very exclusive in tissue selection and growth which means it will not cause heart enlargement or damage to neighboring organs.
SARMs do NOT require the utilization or devouring of liver enzymes to activate their anabolic effects. This eliminates any risk of hepatotoxicity or hepatitis.
Although SARMs such as S-4 are not as powerful as comparable steroids such as Winstrol, they do not require the extensive post cycle therapy and can be cycled back to back throughout the year. Over the course of a year, obtaining the same results is very possible.
SARMs is very female friendly and does not cause excessive masculine features such enlarged sexual characteristics.
S-4 has overall presented larger increases in muscle mass than DHT.
