RAD-140

Description

RAD-140 is the most potent SARM available — a Selective Androgen Receptor Modulator with a reported 90:1 anabolic-to-androgenic ratio, delivering exceptional lean muscle growth, dramatic strength gains, and outstanding body recomposition results. RAD-140 (also known as Testolone) binds to androgen receptors in muscle and bone with exceptionally high affinity while minimising androgenic activity in other tissues — producing maximum anabolic output with a significantly cleaner side effect profile than traditional anabolic steroids. ✔️ Purity ≥99% — Third-party HPLC tested — Made in the USA.

What Is RAD-140 (Testolone)?

RAD-140 is a non-steroidal SARM developed by Radius Health. It achieves one of the highest anabolic-to-androgenic ratios of any compound in the SARM class — reportedly over 90:1 in preclinical models. RAD-140 demonstrates outstanding oral bioavailability and metabolic stability, providing consistent pharmacokinetics across research applications. Unlike LGD-4033 which excels at raw mass, RAD-140 is particularly valued for strength-to-weight ratio improvements and neurological drive. Comparing SARMs to peptides?

RAD-140 Benefits

• Exceptional lean muscle growth: RAD-140 drives rapid lean mass accumulation through selective androgen receptor activation — one of the most anabolically powerful SARMs available
• Dramatic strength gains: RAD-140 users consistently report rapid, significant strength improvements within 2–3 weeks of starting a cycle
• Superior anabolic-to-androgenic ratio: RAD-140 delivers high muscle-building potency with low androgenic activity — minimal impact on prostate and other androgen-sensitive tissues
• Fat loss support: RAD-140 promotes body recomposition — building muscle while supporting fat loss. Stack with GW-501516 (Cardarine) or AOD-9604 for accelerated fat mobilisation alongside muscle growth
• Bone density support: RAD-140 stimulates androgen receptors in bone tissue, supporting bone mineral density
• Neuroprotective properties: Preclinical research suggests RAD-140 may modulate neuroinflammatory pathways — a unique characteristic among SARMs
• Recovery enhancement: Accelerated muscle repair and reduced recovery time between intense training sessions

How to Stack RAD-140

• Lean muscle + endurance: RAD-140 + GW-501516 (Cardarine) — superior lean mass with enhanced fat oxidation. See our Lean Muscle SARMs Stack
• Maximum bulking: RAD-140 + LGD-4033 + MK-677 for maximum lean mass and GH-driven recovery. See our SARMs Bulking Cycle
• Recomposition: RAD-140 + MK-2866 (Ostarine) for lean muscle + joint protection
• Peptide + SARM performance: RAD-140 + Ipamorelin + CJC-1295 — SARM-driven muscle growth + GH peptide recovery and fat loss
• Fat loss + muscle: RAD-140 + AOD-9604 for muscle preservation + direct fat mobilisation. See our SARMs Cutting Cycle

RAD-140 vs Other SARMs

RAD-140 has the most favourable anabolic-to-androgenic ratio of commonly researched SARMs — ideal for maximum muscle growth with minimal androgenic impact. Compared to LGD-4033, RAD-140 edges ahead for strength-to-weight and neural drive while LGD-4033 is better for raw mass. Compared to MK-2866, RAD-140 is significantly more potent and better suited to bulking. Read our Best Peptides for Athletes guide for full protocols.

Post-Cycle Therapy After RAD-140

RAD-140 is significantly suppressive and PCT is essential after every cycle. Use Nolvadex (Tamoxifen) or Enclomiphene for 4–6 weeks post-cycle. Add Ipamorelin during PCT to maintain GH levels and preserve body composition. For men over 40, read our Men Over 40 protocol guide.

RAD-140 FAQ

What is RAD-140 best used for?
RAD-140 excels in lean bulking, strength-focused cycles, and body recomposition. Its outstanding anabolic-to-androgenic ratio makes it one of the most effective SARMs for quality lean mass. For cutting, pair with GW-501516 or AOD-9604.

Can RAD-140 be stacked with peptides?
Yes — RAD-140 and peptides work through entirely different mechanisms. RAD-140 + Ipamorelin + CJC-1295 is one of the most effective lean mass + GH optimisation combinations available. Read our Peptides vs SARMs guide.
