The way that S4 works is by binding to the androgen receptor demonstrating bone and muscular anabolic activity. By binding to the androgen receptors, S4 alters the expression of genes and increases protein synthesis. This leads to the building of quality muscle. S4 can produce muscle growth as steroids do without the type of side effects that steroids produce.


Andarine (GTx-007, S-4) is an investigational selective androgen receptor modulator (SARM) developed by GTX, Inc for treatment of conditions such as muscle wasting, osteoporosis and benign prostatic hypertrophy, using the non-steroidal androgen antagonist bicalutamide as a lead compound.

Andarine is an orally active partial agonist for androgen receptors. It is less potent in both anabolic and androgenic effects than other SARMs. In an animal model of benign prostatic hypertrophy, andarine was shown to reduce prostate weight with similar efficacy to finasteride, but without producing any reduction in muscle mass or anti-androgenic side effects.

This suggests that it is able to competitively block binding to its receptor targets in the prostate gland, but its partial agonist effects at androgen receptors prevent the side effects associated with the anti-androgenic drugs traditionally used for treatment of BPH.

Usage It is a potent and tissue-selective androgen receptor modulator (SARM)

Here are some of the other benefits of Andarine that are worth noting:

· 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 characteristics during the post cycle recovery. [Kearbey et al., 2007]

· 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 as enlarged sexual characteristics.

· S-4 has overall presented larger increases in muscle mass than DHT.
