Ostarine is a SARM (selective androgen receptor modulator) developed by GTX to help treat muscle wasting conditions. These kinds of diseases cause weakness, loss of function, and other symptoms. SARMs are different from steroids because they only target certain parts of the body, making them more selective and less harmful.

How Does Ostarine Work On Your Muscle

You probably have a vague idea of how ostarine works. It binds to muscle and bone cells, which increases protein production in those cells. However, it doesn’t bind to other types of cells in your body (like prostate cancer cells).

You may be thinking: “So what? This sounds like any old anabolic steroid.” And you would be right to think that—but it’s not an anabolic steroid! That’s because Ostarine is a selective androgen receptor modulator (SARM).

What Ostarine Is Made Up Of

Ostarine is made up of chemicals that bind to receptors in muscle and bone cells. This increases their production of proteins, which helps them grow stronger. Ostarine doesn’t have any effect on other types of cells like it does for muscle and bone cells, so there aren’t as many side effects associated with this drug compared to other SARMs or anabolic steroids.

Ostarine is a selective androgen receptor modulator (SARM). This means it’s a type of drug that binds to your androgen receptors. Androgens are hormones that influence muscle growth, including testosterone, DHT, and progesterone.

When you take Ostarine, it binds to the AR (androgen receptor), which is a protein inside your muscle cells. The AR is responsible for signaling cells to grow stronger and larger when they are stimulated by hormones like testosterone or DHT. By binding with the AR, Ostarine can cause more proteins to be produced in your muscles and bones—this makes them grow stronger over time!

The Difference Between SARMs And Anabolic Steroids

The main difference between SARMs and anabolic steroids is that SARMs only affect certain types of cells while steroids affect all types of cells in your body – including liver cells! Because SARMs only target specific areas like bone/muscle tissue while avoiding others such as heart tissue (which could cause cardiac hypertrophy), there aren’t as many side effects associated with this drug compared with other SARMs or anabolic steroids.

How Do You Take Ostarine

Ostarine is an oral supplement, which means it needs to be taken with food. The recommended method of administration is to take one capsule with each meal. This ensures that the body gets a steady stream of nutrients as well as enough protein to maximize muscle growth. If you don’t eat meals at regular times during your day or have a low appetite, then taking Ostarine on an empty stomach may be best for you—but still only once per day.


Ostarine is a safe and effective way to increase muscle mass. It’s also an alternative to steroids, which can have negative side effects on your body. You should talk with your doctor before taking this drug if you have any medical conditions or are taking other prescription medications such as hormone therapy.
