Winstrol (Stanozolol) is a DHT-derived oral anabolic steroid with powerful effects on muscle definition and performance. It does not aromatize into estrogen, making it a preferred choice during cutting cycles where users want to retain lean muscle while reducing body fat. Its anabolic properties promote strength, endurance, and a dry, vascular appearance—making it especially popular among physique athletes and competitive bodybuilders.
Unlike many other orals, Winstrol 15mg may also help reduce SHBG (sex hormone-binding globulin), increasing the availability of free testosterone in the body. While potent, it can be harsh on the liver, so proper cycle planning and liver support are recommended.

Side effects
Despite its benefits, Winstrol 15mg can cause several side effects, especially with improper use:
-
Liver toxicity due to its 17α-alkylated oral structure
-
Joint dryness and discomfort (due to lack of water retention)
-
Suppression of natural testosterone production
-
Androgenic side effects such as acne or hair thinning
-
Cholesterol imbalance (lowered HDL, increased LDL)
Use of a testosterone base, liver support supplements, and proper PCT is strongly advised.
