RAD-140, commonly known as Testolone, is one of the most powerful SARMs (Selective Androgen Receptor Modulators) available today. It is widely used by bodybuilders and fitness enthusiasts for lean muscle gain, strength enhancement, and fat loss without the extreme side effects commonly associated with anabolic steroids.
RAD-140 is especially popular because it delivers dry, hard muscle gains, improves performance, and does not convert to estrogen, making it ideal for those who want clean results. SARMs and Peptides Stack 2025: Gains, Fat Loss & Recovery
What Is RAD-140 (Testolone)?
RAD-140 is a non-steroidal compound designed to selectively bind to androgen receptors in muscle and bone tissue. This selectivity allows it to promote muscle growth while minimizing impact on other organs such as the prostate.
Originally researched for muscle-wasting diseases, RAD-140 became popular in the fitness world due to its strong anabolic nature and relatively manageable side-effect profile when compared to traditional steroids.
How RAD-140 Works in the Body

RAD-140 works by:
- Binding to androgen receptors in muscle
- Increasing protein synthesis
- Enhancing nitrogen retention
- Improving strength and recovery
Because it is selective, RAD-140 avoids unnecessary stimulation of androgen receptors in non-muscle tissues.
RAD-140 Benefits Explained in Detail
1. Lean Muscle Growth
RAD-140 supports pure muscle tissue growth without water retention. Users often notice denser and harder muscles within a few weeks.
2. Significant Strength Gains
Strength increases can be felt as early as week 2, making RAD-140 popular for powerlifting and heavy training phases.
3. Fat Loss & Recomposition
RAD-140 improves nutrient partitioning, meaning calories are more likely to go toward muscle instead of fat.
4. No Estrogen Conversion
Since RAD-140 does not aromatize, there is no estrogen-related bloating or gynecomastia.
5. Muscle Preservation During Cutting
Ideal for calorie deficits, helping retain lean mass while dieting.
