Overview of S4 Andarine
S4, also referred to as Andarine, is a non-steroidal selective androgen receptor modulator (SARM). It was developed to target androgen receptors in muscle and bone tissues. It acts as a partial agonist and selectively stimulates anabolic pathways in these tissues. It has minimal effects on other organs of the subject. S4 contributes to lean muscle development, improves muscle strength, and increases fat metabolism in research models.
Studies indicate that S4 preserves muscle mass and increases the ratio of muscle to fat in research models. Its anabolic effects are moderate compared to some other SARMs. The potential of S4 to promote muscle hardness and vascularity makes it beneficial for research related to lean tissue enhancement and metabolic activity in research.

Andarine’s Mechanism of Action in Research Models
S4 works by selectively binding to androgen receptors in skeletal muscle and bone in test models. This interaction activates anabolic pathways that promote protein synthesis, muscle growth, and bone formation. It acts as a full agonist in muscle and bone tissues and shows partial agonist activity in other androgen-sensitive tissues in models.

Frequently Asked Questions
Are S4 Andarine Capsules legal?
Andarine is not approved for human use by the FDA. This compound remains a research chemical, and it is available for research purposes in the United States.
What are the effects of Andarine in research models?
Andarine increases lean muscle mass and supports bone strength in research models. Some cell-based research also shows that S4 reduces cancer-cell growth, but these findings are limited to laboratory conditions.
How long is Andarine detectable in test models?
Andarine has a half-life of roughly 2 to 5 hours in research models. This means it is rapidly cleared from the system.
What are the risks associated with S4 in research conditions?
S4 carries documented risks in research. The reported adverse effects include vision disturbances, liver toxicity, and increased risk to other vital parts in research models.
What is the best place to buy Andarine Capsules online?
Experts recommend reputable brands for research-based products like Andarine (S4) Capsules. Iron Mountain Labz is one of the researchers’ favorite online brands, because our SARMs are tested for ingredients’ purity. Our products come with a Certificate of Analysis for research verification. We sell SARMs in different forms, such as capsules, liquids, and injectables, for research.
