RAD 140 (Testolone) is a selective androgen receptor modulator (SARM) used primarily for muscle growth, strength enhancement, and fat loss. Before and after results from users typically show noticeable muscle gains and fat loss within a few weeks to a couple of months of use. For example, a typical cycle of 8 weeks with 30 mg/day has shown muscle gains of around 21 lbs and fat loss of about 12 lbs. Other users report lean mass gains around 10 pounds and improved muscle hardness and definition, although some also note side effects like mild hair loss or increased visceral fat when stacked with other substances. The cycle usually lasts 2-3 months, followed by a recovery period to maintain gains and balance hormone levels. A few user testimonials indicate gains of 4 to 6 kg (9-13 lbs) of lean mass over 8 weeks, alongside strength improvements and muscle size increases. Some users experience increased libido and aggression, but less intense than with stronger SARMs or steroids. Proper post-cycle therapy (PCT) is recommended to restore natural testosterone production. Overall, RAD 140 before and after results show solid muscle growth and fat loss, with fewer side effects than anabolic steroids, although long- term safety is still unclear due to ongoing research.
