S-BOL10 is one of the most popular and well-known anabolic steroids in the world. It was developed by Winthrop Laboratories in the late 1950s and has attracted media attention over the years. Even people who have never used anabolic steroids, if anyone can name one, it’s usually Winstrol or Stanozolol. The name Winstrol is actually the most popular trade name for the anabolic steroid Stanozolol. It enjoys worldwide attention because of the many sports scandals over the years. When athletes have been caught using anabolic steroids, Winstrol has been at the forefront countless times.

Purpose and properties of S-BOL10

S-BOL10 (Stanozolol) is an anabolic androgenic steroid, a derivative of dihydrotestosterone (DHT) or, more specifically, its structurally modified form. Stanozolol is a DHT with two structural changes. The first change is the addition of a pyrazole group to the A-ring replacing the 3-ketone group. This modification officially classifies stanozolol as a heterocyclic steroid. S-BOL10 (stanozolol) also has a methyl group added to preserve the hormone after oral administration. This structural change occurs at the 17th carbon position, which officially classifies stanozolol as a C17-alkylated (C17-AA) anabolic steroid.

This combination of structural changes significantly reduces the androgenicity of S-BOL10 (stanozolol) and greatly increases its anabolic potential. Officially, the anabolic class of S-BOL10 (stanozolol) is 320 and its androgenic class is 20. Most importantly, its levels exactly match its actual action, giving us an extremely useful anabolic steroid.

S-BOL10 (stanozolol) has many positive properties as an anabolic steroid, one of which is its ability to significantly reduce levels of sex hormone binding globulin (HSPG). This allows more of the steroid taken to remain unbound and provides an increase in free testosterone levels. While many steroids reduce HSPG, S-BOL10 (stanozolol) appears to have a much stronger affinity for it than most others. Studies have shown a reduction in HSPG by about 50% in just a few days, even at relatively low doses.
