S4, commonly known as Andarine, is a selective androgen receptor modulator investigated for anabolic activity involving muscle and bone tissue.

Product Information

Andarine was developed as a selective androgen receptor ligand and has been studied in preclinical models for anabolic and tissue-selective effects. S4 is also among the SARMs monitored in anti-doping research.

How It Works

S4 binds to androgen receptors and influences androgen-responsive gene expression. Its selective activity allows researchers to investigate anabolic signaling in skeletal muscle and other tissues.

POTENTIAL BENEFITS

1. Muscle Research

S4 has been investigated for anabolic activity in skeletal muscle. Its androgen-receptor action makes it relevant to research involving muscle growth and maintenance.

2. Bone Research

Androgen receptors are important to skeletal physiology, and S4 has been investigated as part of the broader development of SARMs targeting muscle and bone.

3. Selective Androgen Signaling

Compared with conventional anabolic steroids, SARMs are designed to provide more tissue-selective androgen-receptor activity.

4. Body-Composition Research

S4 remains of interest in experimental research examining the relationship between androgen signaling, lean tissue, and body composition.

Dosage

There is no established clinical dosage for S4. Online bodybuilding communities discuss various oral schedules, but those reports do not establish a medically validated dose.

Side Effects

A notable concern associated with S4 is visual disturbance, including altered night vision or changes in color perception. Other potential concerns include testosterone suppression and lipid changes.
