RAD-140, also known as Testolone, is a selective androgen receptor modulator (SARM) that was developed as an experimental treatment for conditions like muscle wasting, breast cancer, and age-related degeneration. Produced mainly in the testes (and in smaller amounts by the ovaries and adrenal glands), testosterone regulates a wide range of biological functions — from muscle growth and fat distribution to libido, mood, and bone density. Over the past decade, selective androgen receptor modulators (SARMs) like RAD-140 (Testolone) have gained huge popularity in bodybuilding circles. It is best recommended for users to take PCT after every cycle to help the body normalize its hormonal levels. RAD140 Testolone is an effective and safe SARM for lean muscle growth without the usual side effects of other SARMs that is muscle wasting. This milder combination can give lean muscle mass up to 10 lbs in eight weeks and some cutting effects. However, MK-677 is technically a growth hormone secretagogue (GHS). WADA states that RAD-140 and other SARMs can undermine the spirit of sports, leading to unfair advantages, while compromising the health of athletes. Sports Technology Labs is a highly cost-effective US SARM source, offering purity levels exceeding 98%, as confirmed by their certificates of analysis. US orders are delivered within 2–5 days, while international orders typically arrive in 4–7 days. There is limited clinical research regarding RAD-140’s effects, particularly on humans over the long term. Dr. Thomas O’Connor has firsthand experience treating thousands of men who have taken performance-enhancing drugs, including RAD-140, and states that it is not primarily used by bodybuilders. Preclinical data suggest RAD-140 is anabolically potent per milligram, comparable to moderate testosterone doses ( mg/week). RAD-140 produces liver enzyme elevation in some users, with documented cases of significant DILI (drug-induced liver injury). While prostate stimulation may be less than equivalent testosterone doses, it's not eliminated—monitor PSA during and after cycles. Dose-dependent increases in strength have been reported anecdotally and are consistent with the compound's mechanism of action as a potent AR agonist in skeletal muscle. When used responsibly, RAD140 poses minimal liver toxicity, but improper dosing or prolonged use can elevate liver enzymes and increase health risks. Blood tests can help monitor hormone levels and detect any adverse effects during SARM use. In some cases, a liver biopsy may be necessary to assess potential liver damage from prolonged or high-dose use. The amalgamation of these ingredients in clinical-range dosages do not exhaust your body nor create side effects. Radbulk does not supply artificial hormones or tweak your biological processes to support your muscle building and fat loss. The company delivers its products worldwide offering a range that is safe, effective, and health-friendly. RAD-140 also protects the brain, may prevent Alzheimer s disease, and increases fats burning. Dr. O’Connor also co-authored the largest survey on anabolic steroid use, involving 2,385 men, published in the peer-reviewed American Journal of Men’s Health. Dr. O’Connor has over 20 years of experience treating men and women with a history of anabolic steroid, SARM, and PED use. Such deteriorations in health are evident in several human trials and correlate with Dr. Thomas O’Connor’s ten years of experience treating males and females on RAD-140. RAD140 can suppress natural testosterone production during and after use, but it typically does not cause permanent damage if proper post-cycle therapy (PCT) is followed. The choice between the two depends on individual goals, experience level, and tolerance for potential side effects. Post-cycle therapy (PCT) is typically recommended after using either SARM to help restore natural hormone levels. Additionally, RAD-140 can help reduce body fat while preserving lean muscle tissue. RAD-140 users often report increased muscle mass, improved strength, enhanced endurance, and faster recovery times. In preclinical studies, RAD-140 demonstrates a significant increase in lean body mass and muscle hypertrophy.
