RAD 140, also known as Testolone, is a second‑generation SARM developed to provide anabolic benefits without the full spectrum of androgenic side effects associated with testosterone. It exhibits high affinity and specificity for androgen receptors, particularly in muscle and bone tissue, making it one of the most studied SARMs in this category. Research suggests it may support lean muscle growth, strength gains, and muscle retention during calorie restriction, while potentially aiding in fat loss.
Unlike testosterone, RAD 140 does not convert to estrogen or dihydrotestosterone, reducing risks of hormonal imbalance. However, because it still interacts with androgen receptors, it can influence natural testosterone levels during and after use. SwissChems markets RAD 140 in capsule form (10 mg per capsule, 60 capsules per bottle), highlighting its bioavailability and potency. The product is sold with disclaimers: it is not FDA‑approved, not intended to diagnose, treat, cure, or prevent disease, and is strictly for developmental research purposes
