RAD140 TESTOLONE

Selective Androgen Receptor Modulator (SARM) for Research

VST Research Labs RAD140, also known as **Testolone**, is a research‑grade selective androgen receptor modulator (SARM) designed for laboratory investigation into pathways related to **lean muscle growth, strength signalling, performance, and anabolic processes**. RAD140 has been studied as a potential alternative to traditional anabolic agents due to its **tissue‑selective action on androgen receptors** in muscle and bone. 

Main Research Benefits of RAD140 (Testolone)

• Supports anabolic signalling and investigation into lean muscle development in controlled research settings
• May assist strength and performance pathway research
• Explored in pre‑clinical studies for **fat mass modulation** and muscle preservation while engaging anabolic pathways 
• High affinity for muscle and bone androgen receptors with minimal action in non‑target tissues 
• Non‑steroidal compound often used to model anabolic effects without typical steroid profiles in experimental designs 

How RAD140 Works (Research Mechanism)

RAD140 (Testolone) selectively binds to **androgen receptors** in skeletal muscle and bone tissue, stimulating anabolic processes while exhibiting a lower tendency to engage receptors in non‑target tissues. This targeted mechanism enables researchers to investigate **lean muscle and performance pathways** with reduced off‑target effects compared to traditional anabolic steroids. 

Because RAD140 avoids conversion to oestrogen and has minimal interaction with other hormone pathways, it’s frequently included in experimental studies focused on **body composition, strength, and endurance signalling**.

Product Features & Specifications

• Brand: VST Research Labs

Suggested Research Usage

In research or laboratory protocols, RAD140 is typically studied using consistent daily dosing to maintain engagement of androgen receptors throughout the experiment. Because of its oral bioavailability and relatively long half‑life — commonly around ~20 hours in laboratory studies — once daily administration is frequently used in experimental designs. 

⚠️ Important: VST Research Labs RAD140 (Testolone) is intended solely for research use.

Frequently Asked Questions

What is RAD140 (Testolone)?

RAD140, often referred to as Testolone, is a **selective androgen receptor modulator (SARM)** developed to target androgen receptors in muscle and bone tissue while limiting interaction with non‑target tissues — making it useful for lean muscle and performance pathway research. 

Preclinical research indicates RAD140 may support **lean muscle signalling, strength, and fat modulation pathways**, offering a model for anabolic biology studies without some of the side effect profiles seen with traditional anabolic steroids. 

Does RAD140 convert to oestrogen?

No — RAD140 does *not* aromatise to oestrogen, which means it does not convert into estrogenic compounds in standard laboratory models and retains its selective mechanism of action.

Is RAD140 approved for human use?

No — RAD140 is supplied for **laboratory and research use only** and is not approved as a drug, supplement, or therapeutic for human or veterinary use.
