S4 (Andarine)

Andarine, also known as S4, is classified as a Selective Androgen Receptor Modulator (SARM). It belongs to the first generation of SARMs and is considered one of the oldest substances in this category.

S4 is often compared to Winstrol or Anavar due to its ability to create a "pre-strength physique." It helps in achieving a dry, well-defined, and aesthetic muscle appearance, giving the illusion of a lower body fat percentage.

Unlike Winstrol, Andarine has the advantage of causing fewer significant side effects, thanks to its SARM properties.

SARMs selectively bind to androgen receptors primarily found in muscles and bones. These receptors play a crucial role in muscle tissue development as they interact with the sex hormones responsible for anabolic effects. The quantity and sensitivity of androgen receptors in our body largely determine our ability to build muscle.

Due to their selective nature, SARMs generally have milder side effects compared to steroids or hormones, although some substances may still exhibit certain side effects.

Benefits:

Dry Body: Similar to Winstrol or Anavar, S4 provides excellent muscle fullness from the early stages of usage. It creates the optical illusion of a lower body fat percentage and enhances vein visibility.

Muscle Mass Gain: Andarine is known for its strong anabolic properties among SARMs. It promotes rapid and high-quality muscle mass gain within a relatively short period (visible effects can be observed after approximately 3 weeks of use).

Increased Strength: Thanks to its androgenic activity, S4 significantly boosts strength. Users typically experience noticeable strength gains after 2-4 weeks of use.

Increased Bone Density: Andarine's primary benefit lies in its interaction with androgen receptors in the bones, leading to increased bone density. This advantage is particularly valuable for older individuals and those at a higher risk of fractures.
