GenShi Labs Stanozolol 25 mg offers a potent oral anabolic steroid commonly known as Winstrol or "Winny," ideal for cutting cycles and increasing athletic performance.

Stanozolol is favored for its ability to promote fat loss while preserving lean muscle. Unlike many anabolic steroids, it doesn't convert to estrogen, making it a go-to for dryness, vascularity, and muscle definition. It also enhances strength without excessive bulk, which is why it's widely used in sports like MMA, sprinting, and bodybuilding.
Stanozolol was originally developed for medical use in conditions such as angioedema and muscle-wasting diseases. According to research published on PubMed, its anabolic-to-androgenic ratio makes it effective at promoting muscle retention with fewer androgenic side effects compared to other orals.
Typical dosing for performance enhancement ranges from 25 to 50 mg per day, split into two doses for optimal blood level stability. Cycle duration should not exceed 6–8 weeks due to liver stress. For men, 50 mg/day is common during a cutting phase. For women, 5–10 mg/day is considered a safer threshold.
Stanozolol stacks well with non-aromatizing injectables and mild compounds. For enhanced muscle hardness and strength, consider the following:
For improved fat loss:
Since oral Winstrol is hepatotoxic, it's recommended to pair it with liver support like TUDCA. Post-cycle therapy (PCT) is essential to restore natural testosterone levels after cycle completion. A 4-week protocol with Clomid 50 mg is often used.
While Stanozolol doesn't cause estrogen-related side effects, it can lead to joint dryness, elevated LDL cholesterol, liver stress, and androgenic effects such as hair loss in predisposed individuals. Adequate hydration, joint support supplements, and cycle length management can help minimize risks.
