S4 ANDARINE

Selective Androgen Receptor Modulator (SARM) for Lean Muscle & Definition

Nordic Labs S4 Andarine is a research‑grade selective androgen receptor modulator (SARM) designed for laboratory investigation into lean muscle pathways, strength signalling, and body composition research. Also known as S‑4 (Andarine), this compound selectively binds to androgen receptors in muscle and bone tissue — promoting anabolic mechanisms with reduced non‑target effects compared with traditional anabolic agents. 

Main Research Benefits of Nordic Labs S4 Andarine

• Supports investigation into lean muscle maintenance and growth pathways
• May assist research into fat metabolism and body composition modulation
• Useful for strength and endurance signalling studies
• Non‑hormonal compound with selective tissue activity
• Investigated for bone‑related anabolic pathways in controlled studies

In research settings, Andarine is often explored in cutting or recomposition protocols where both muscle preservation and fat utilisation are key areas of study. 

How Andarine Works

Andarine (S‑4) is chemically classed as a SARM, meaning it selectively activates androgen receptors in targeted tissues like muscle and bone without strongly engaging receptors in other organs. Research shows this selective activation may help maintain protein synthesis pathways while promoting metabolic efficiency — making it a compound of interest for lean mass and cut‑phase studies. :contentReference[oaicite:2]{index=2}

Some laboratory investigations also highlight Andarine’s role in enhancing lipolysis and reducing fat storage enzyme activity — potentially supporting fat reduction research when paired with energy balance studies.

Ingredients & Specifications

• Active Compound: Andarine S4 – 25 mg per capsule
• Other Ingredients: Magnesium Stearate, Silicon Dioxide (typical inactive carriers) 
• Servings: 60 Capsules per Bottle
• Form: Capsule – convenient daily dosing
• Use: Research and laboratory investigation only — not approved for human or veterinary use

Suggested Research Usage

In experimental settings, researchers often administer one capsule daily with food to support stable receptor engagement, or may split doses (e.g., morning and early afternoon) to maintain compound levels due to Andarine’s moderate half‑life.

Frequently Asked Questions

What is Andarine (S4)?

Andarine, also called S‑4, is a selective androgen receptor modulator (SARM) that selectively targets androgen receptors in muscle and bone tissues — making it useful for studies into lean muscle and body composition pathways. 

What are the main benefits for research?

In controlled studies, Andarine may support lean muscle signalling, strength research, and fat metabolism pathways — particularly in cutting or recomposition investigation protocols. 

Is Andarine approved for human use?

No — Andarine is intended for research use only and has not been approved by any major regulatory authority for human or veterinary use.

Are there known effects to monitor?

Anecdotal reports and some preclinical data note that Andarine may affect visual perception (e.g., temporary yellow tint), potentially due to receptor interactions in eye tissue; however, this is an observation from independent communities rather than formal clinical approval.
