RAD-140 (Testolone): Benefits, How to Use It & Do You Need PCT?

RAD-140, also known as Testolone, is one of the most powerful SARMs (Selective Androgen Receptor Modulators) available today. Designed to mimic the effects of testosterone in muscle and bone tissue — without the side effects of steroids — RAD-140 has become a go-to choice for athletes and bodybuilders seeking rapid lean muscle growth and improved strength.

At DiscountedSARMs.co.uk, we stock only lab-tested, high-purity RAD-140 so you can research with confidence.


💪 What Is RAD-140?

RAD-140 was originally developed as a testosterone replacement therapy alternative, offering anabolic effects similar to testosterone but with greater tissue selectivity and fewer unwanted side effects.

Unlike anabolic steroids, RAD-140 does not convert to estrogen or significantly affect the prostate or liver, making it a safer option for performance enhancement and physique transformation.


✅ Benefits of RAD-140

1. Rapid Lean Muscle Gains

RAD-140 is known for producing dry, lean muscle mass gains in a short period. Users often report gaining 5–10 lbs of muscle in an 8-week cycle when paired with proper training and nutrition.

2. Increased Strength & Power

Thanks to its potent anabolic action, RAD-140 can lead to faster strength progression, enhanced endurance, and better workout performance overall.

3. Fat Loss & Recomposition

Testolone promotes fat loss while preserving muscle mass, making it ideal during cutting cycles or body recomposition phases.

4. Neuroprotective Effects

One unique feature of RAD-140 is its potential neuroprotective properties, as observed in clinical research. This may benefit long-term cognitive health¹.

5. Improved Vascularity & Definition

Because RAD-140 doesn’t cause water retention, users typically see dry gains with improved vascularity, muscle hardness, and definition.


📅 How to Use RAD-140

Typical Dose: 10–20 mg daily

Cycle Length: 6 to 8 weeks

Half-Life: ~20 hours (once-daily dosing is sufficient)

🔄 Stack Compatibility

RAD-140 can be used:

Solo, for beginners or during a first cycle

Stacked, with other SARMs like LGD-4033 or MK-677 for advanced results

⚠️ Due to its potency, RAD-140 should not be run for longer than 8–10 weeks without a break.


❓ Does RAD-140 Require PCT?

Yes, a PCT is recommended after using RAD-140.

Although RAD-140 is a SARM and not a steroid, it is strong enough to suppress natural testosterone production in many users. PCT (Post Cycle Therapy) helps your body restart natural testosterone levels and maintain the gains made during your cycle.

🔁 PCT Options:

Milder cycles (10mg for 6 weeks) may require only a natural testosterone booster

Heavier cycles (20mg+ or stacks) should include a PCT with Clomid or Nolvadex for 4 weeks

Always assess your own response and consider bloodwork to determine suppression levels.
