What is Andarine?
Andarine, also known as S-4 and GTx-007, is a drug that belongs to the Selective Androgen Receptor Modulators, or SARMs for short. These compounds are being researched and developed as a possible safer alternative to anabolic-androgenic steroids (
It was initially developed to treat osteoporosis and muscle wasting. It quickly became popular among bodybuilders and athletes because of its muscle building and fat burning capabilities.
How does Andarine work?
Andarine works much in the same way as anabolic steroids. Both target the androgen receptors in the body, resulting in an increase in muscle mass, enhanced fat burning and faster recovery.
But unlike anabolic steroids, SARMS, such as S-4, are more selective in the type of tissue they target. While anabolic steroids target all androgen receptors in the body, Andarine mainly targets the receptors in skeletal muscle, and the eyes.
Andarine benefits
The main benefits associated with this SARM are:
- Increased muscle mass
- Fat loss
- Faster recovery
- Body recomposition
- Increased strength
Side effects of Andarine
The most common side effects associated with S4 are:
- Testosterone suppression
- Impaired vision
Testosterone suppression
While Andarine is a type of SARM that can have an impact on the production of Testosterone, it is important to note that this impact is typically far less severe than what is experienced with anabolic steroids. While Andarine may suppress the natural production of Testosterone to a certain degree, it does not cause the same level of suppression as steroids.
Stacking
Andarine is often stacked with other SARMs such as Cardarine (GW-501516) and Ostarine (MK-2866) for better results.
