Testolone RAD 140

RAD-140, known as Testolone, is a selective androgen receptor modulator (SARM) that binds to androgen receptors in muscle and bone tissue. It is designed to promote lean muscle gains and support fat loss while producing less impact on other organs than traditional anabolic steroids. Most users run it for recomposition, aiming to add size and strength while staying relatively lean.

As a guide and not medical advice, first-time users commonly start around 10mg per day taken orally with food, for a cycle of around 8 weeks. More experienced users sometimes go higher, but pushing dose or duration raises the risk of testosterone suppression. Always start conservative and judge your own response before considering any increase.

Yes. RAD-140 commonly suppresses natural testosterone production, so a post-cycle therapy protocol using something like Clomid or Nolvadex is generally recommended, usually starting around two weeks after the last dose. It is also processed by the liver, so pairing it with a liver support product such as one containing NAC or milk thistle is a sensible precaution.

Reported effects include suppressed natural testosterone, mildly elevated liver enzymes, headaches, and disrupted sleep. These are usually managed by sticking to a sensible dose, not extending the cycle unnecessarily, and running proper PCT afterward. Anyone with existing liver or hormonal concerns should speak to a doctor before use.

RAD-140 builds muscle and strength through androgen receptor activity, while Cardarine (GW-501516) works through a different pathway to support fat loss and endurance without adding androgenic effects. Many users combine the two for a recomposition cycle, using RAD-140 for mass and Cardarine to keep conditioning and stamina up. They are not interchangeable, since only RAD-140 carries a real muscle-building effect.
