RAD-140, also known as Testolone, is a selective androgen receptor modulator (SARM) investigated for anabolic activity involving skeletal muscle and bone. It has become particularly prominent in muscle-growth and performance-related research.

Product Information

RAD-140 selectively interacts with androgen receptors and has been investigated for anabolic effects while attempting to produce less activity in certain androgen-sensitive tissues than traditional anabolic steroids. Recent preclinical work has examined its effects on muscle mass and bone mineral density.

How It Works

RAD-140 binds to androgen receptors in tissues such as skeletal muscle and bone. Activation of these receptors influences gene expression involved in anabolic processes, including muscle protein synthesis and tissue growth.

POTENTIAL BENEFITS

1. Muscle-Growth Research

Preclinical studies have reported increased muscle fiber size and anabolic effects following RAD-140 exposure. This is one of the primary reasons it continues to attract research interest.

2. Lean-Mass Research

By activating androgen receptors, RAD-140 has been investigated for its potential influence on skeletal muscle mass and body composition.

3. Bone Research

Research has also examined RAD-140 in relation to bone mineral density, making it relevant to studies investigating androgen-receptor signaling in skeletal tissue.

4. Selective Androgen-Receptor Activity

RAD-140 was designed to provide anabolic androgen-receptor activity with greater tissue selectivity than conventional anabolic steroids. This pharmacological profile is central to its research interest.

Dosage

There is no established clinical dosage for RAD-140. Online bodybuilding communities commonly discuss daily oral administration, but these user-reported protocols have not established a medically validated or universally appropriate dose.

Side Effects

Potential concerns include suppression of natural testosterone production, unfavorable lipid changes, and liver-related effects. Human case reports have also described acute liver injury and myopericarditis associated with RAD-140 use.
