Testolone (RAD-140) – Extreme Strength & Lean Gains | 15mg, 60 caps

RAD-140 (Testolone): High-Potency SARM for Muscle Hypertrophy

DISCLAIMER: For research purposes only. Not for human or veterinary use.

RAD-140, also known as Testolone, is a powerful and popular Selective Androgen Receptor Modulator (SARM). Engineered by Radius Health Inc. to treat muscle wasting and osteoporosis, it is designed to mimic the anabolic effects of testosterone with significantly greater tissue selectivity. This makes it one of the most sought-after compounds for research into rapid muscle growth and strength enhancement.

Chemical & Biological Properties

• IUPAC Name: 2-chloro-4-[(1R,2S)-1-[5-(4-cyanophenyl)-1,3,4-oxadiazol-2-yl]-2-hydroxypropyl]benzonitrile
• CAS Number: 1182367-47-0
• Molecular Formula: C₂₀H₁₆ClN₅O₂
• Molar Mass: 393.83 g/mol
• Elimination Half-Life: Approximately 16–20 hours, ideal for once-daily dosing.
• Binding Affinity: Extremely high affinity for androgen receptors, surpassing testosterone in anabolic potency.

Mechanism of Action

RAD-140 selectively binds to androgen receptors in skeletal muscle and bone tissue. It stimulates anabolic activity without significantly impacting the prostate, liver, or other organs. Crucially, Testolone does not aromatize into estrogen, eliminating the risk of water retention and gynecomastia.

Potential Research Benefits

• Explosive Lean Muscle Mass: Promotes rapid and significant gains in muscle size and raw strength.
• Fat Oxidation: Helps maintain muscle mass while shifting the body's energy preference toward burning fat.
• Enhanced Bone Density: Improves bone mineral density, supporting skeletal strength during heavy lifting.
• Neuroprotective Effects: Early studies suggest RAD-140 may provide protective benefits for brain cells.
• Dry Gains: Provides a hard, vascular look due to the lack of estrogen conversion.

Recommended Cycling Protocols

Due to its high potency, RAD-140 protocols require careful planning regarding dosage and cycle length.

1. Standard Research Cycles

• Beginner: 6–8 weeks at 10 mg/day.
• Intermediate: 8–10 weeks at 15 mg/day.
• Advanced: 10–12 weeks at 20 mg/day (Higher doses increase the risk of severe suppression).

2. Goal-Specific Stacks

• Bulking: 15–20 mg/day for 8 weeks. Often paired with MK-677 or LGD-4033 for maximum hypertrophy.
• Cutting: 10–15 mg/day for 8–10 weeks. Commonly combined with Cardarine (GW-501516) to shred fat while preserving muscle.
• Recomposition: 15 mg/day for 8–10 weeks. Often stacked with Ostarine (MK-2866) or S4 (Andarine).

Side Effects & Detection Time

• Testosterone Suppression: Moderate to high. Natural production will likely drop, requiring recovery time.
• Liver Health: Possible elevation of liver enzymes with prolonged use.
• Mood & Well-being: Anecdotal reports mention occasional headaches, mood swings, or increased aggression.
• Detection: Traceable in urine for up to 8 days after a single 10 mg dose; metabolites may linger for several weeks with repeated use.

Post-Cycle Therapy (PCT)

Is PCT required? YES. RAD-140 is highly suppressive. A 4–6 week PCT using Clomid (25–50 mg) or Nolvadex (20–40 mg) is strongly recommended to restore natural testosterone levels. PCT should ideally begin the day after the cycle concludes.
