Glossary: Tissue Selectivity
What Is Tissue Selectivity? (Simple Definition) Tissue selectivity is the ability of a drug or compound to activate receptors in some tissues while avoiding others.With SARMs, this means switching on muscle- and bone-building signals without strongly activating androgenic pathways in the prostate, skin, or hair follicles. It’s the core scientific reason SARMs exist. Why Tissue …

Does RAD140 Increase or Decrease Testosterone?
Evidence from Human Clinical Trials TL;DR:Clinical trial data shows that RAD140 decreases natural testosterone levels through suppression of the hypothalamic-pituitary-gonadal (HPG) axis. Despite its anabolic properties, it does not raise testosterone, and suppression has been observed even at therapeutic doses. Key Takeaways: Does RAD140 Increase or Decrease Testosterone? What Clinical Trials Say About RAD140 and …
