Winstrol, also called stanozolol, is an anabolic steroid. Medically, it has been used mainly to help prevent hereditary angioedema attacks, but it’s better known for its performance-enhancing and physique-related use because it can promote lean muscle retention and a harder, drier look.

What it does

  • Increases anabolic activity, which can support muscle maintenance and growth.
  • Can reduce water retention, which is one reason some athletes/bodybuilders use it for a leaner appearance.
  • Has limited legitimate medical use, mainly for hereditary angioedema prevention.

Main risks

  • Liver toxicity, including serious liver injury.
  • Worse cholesterol profile, with lower HDL and higher LDL, which raises cardiovascular risk.
  • Other steroid-related side effects, including hormonal suppression and possible long-term health harms.

Important note

Winstrol is a controlled anabolic steroid in many places and should only be used under medical supervision when legally prescribed.

TL;DR

It’s a steroid that can help preserve lean mass and reduce water retention, but it comes with significant health risks, especially to the liver and heart.
