99% Purity Hormone Steroid Powder Injectable or Oral Stanozolol/Winstrol/Winny/Stanol CAS 10418-03-8 For Muscle Gain and Fat Loss
Stanozolol, commonly sold under the name Winstrol (oral) and Winstrol Depot (intramuscular), is a synthetic anabolic steroid derived from dihydrotestosterone. It was developed by American pharmaceutical company Winthrop Laboratories (Sterling Drug) in 1962, and has been approved by the FDA for human use.
Unlike most injectable anabolic steroids, stanozolol is not esterified and is sold as an aqueous suspension, or in oral tablet form. The drug has a high oral bioavailability, due to a C17 alpha-alkylation which allows the hormone to survive first-pass liver metabolism when ingested. It is because of this that stanozolol is also sold in tabletform.
