RAD-140, commonly known as Testolone, is a highly selective androgen receptor modulator (SARM) developed to support lean muscle growth, strength progression, and performance output. It is widely regarded as one of the most potent SARMs due to its strong anabolic signalling and targeted action.
RAD-140 is designed to focus on muscle and bone tissue, making it a popular choice during lean bulking, strength, and recomposition phases.
Key Benefits
- Supports lean muscle growth and size
- Helps increase strength and power output
- Highly selective to muscle and bone tissue
- Supports muscle retention during intense training
- May assist with bone density and structural strength
- Non-aromatising (does not convert to estrogen)
- Popular for lean bulking and performance protocols
