RAD-140 (Testolone): The Ultimate Guide to Strength, Size, and Shredded Gains

Looking for explosive muscle growth and next-level performance — without the harsh side effects of steroids?
RAD-140 (Testolone) is one of the most powerful SARMs on the market and a go-to for bodybuilders and athletes seeking size, strength, and dry gains.

In this article, we’ll break down everything you need to know about RAD-140, how it works, what the research says, and how to get research-grade Testolone at aminoxgen.com.

What Is RAD-140?

RAD-140, also known as Testolone, is a Selective Androgen Receptor Modulator (SARM) developed by Radius Health to help treat muscle wasting and breast cancer.

Its goal was to replicate the effects of testosterone — without the unwanted side effects associated with traditional anabolic steroids.

• Classification: SARM

• Half-Life: ~20 hours

• Original Purpose: Preserve muscle in patients with age-related or disease-related wasting

Today, it’s used by athletes and researchers for its potent anabolic effects, clean strength gains, and fast physique changes.

How RAD-140 Works

RAD-140 selectively binds to androgen receptors in muscle and bone, triggering anabolic activity (aka muscle-building) without affecting the prostate, liver, or other sensitive tissues.

Benefits include:

• Enhanced protein synthesis

• Increased nitrogen retention

• Boosted strength and endurance

• Zero conversion to estrogen or DHT

This makes RAD-140 a top-tier choice for bulking, recomping, or even cutting, depending on your stack and diet.

What the Science Says

While RAD-140 is still classified as a research chemical, several studies have confirmed its potent anabolic effects:

🧪 Preclinical Studies (2010–2017)

• Shown to increase lean body mass in primates and rodents

• Demonstrated strong neuroprotective properties

• Comparable anabolic activity to testosterone at a fraction of the dose

• Minimal androgenic side effects
