Stanozolol, widely known by its pharmaceutical brand name Winstrol, is a synthetic anabolic compound derived from dihydrotestosterone (DHT) with one of the most well documented histories in both pharmaceutical and sports science research. CSD’s injectable formulation delivers 50mg/mL in a 10mL multi dose vial; a less common presentation than oral Stanozolol tablets, offering an alternative delivery route that bypasses first pass hepatic metabolism associated with oral administration.
The injectable format of Stanozolol is a meaningful research distinction from its oral counterpart. Oral Stanozolol undergoes significant first pass liver processing before reaching systemic circulation, whereas injectable administration delivers the compound directly into the bloodstream. This difference in bioavailability pathway makes injectable Stanozolol a distinct research subject from oral preparations, particularly in studies examining hepatic load comparisons, dose response relationships, and systemic anabolic activity independent of first pass processing an area where injectable Stanozolol shares research parallels with CSD’s injectable Oxymetholone formulation.
Stanozolol is structurally distinct from most anabolic compounds in that it does not aromatise under any circumstances and does not convert to estrogen regardless of dose. As a DHT derived compound it also cannot be converted to a more androgenic metabolite, giving it a well characterized and predictable interaction profile in androgen receptor research. Stanozolol has a documented pharmaceutical history spanning decades, having been clinically approved for treating hereditary angioedema and anemia, which contributes to its extensive presence in the clinical literature relative to many other anabolic compounds.
Every batch of CSD’s injectable Stanozolol is third party lab tested for concentration accuracy and purity prior to release, with COA documentation available on request. Canada Steroid Depot has supplied Canadian customers with consistently verified, accurately dosed compounds for years, and our injectable Winstrol formulation is one of the more specialized offerings in our anabolic range. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.

Injectable Winstrol (Stanozolol) is an aqueous suspension of Stanozolol delivered intramuscularly rather than orally. Despite being a 17-alpha alkylated compound which is unusual for injectable steroids. Injectable Stanozolol bypasses first pass liver metabolism, theoretically reducing hepatic stress compared to oral tablets while delivering the compound directly into systemic circulation. Injectable Stanozolol also has a slightly longer half-life than the oral form; approximately 24 hours versus 8–9 hours for oral tablets, allowing once daily administration rather than twice daily dosing. Milligram for milligram, injectable Stanozolol achieves higher bioavailability than the oral formulation.
Stanozolol is a dihydrotestosterone (DHT) derivative with a high anabolic to androgenic ratio that does not aromatize to estrogen and does not bind progesterone receptors; making it one of the cleanest anabolic compounds in terms of estrogen and prolactin management requirements. It is researched for lean mass preservation, strength enhancement, vascularity, muscle hardness, and fat loss in cutting research protocols. Stanozolol is also studied for its significant negative impact on lipid profiles, severely reducing HDL and elevating LDL, making lipid monitoring and management an essential component of any Stanozolol research protocol.
Injectable Stanozolol is an aqueous suspension. The Stanozolol particles are suspended in water rather than dissolved in oil, meaning the compound settles at the bottom of the vial between uses. Shake the vial thoroughly before drawing each dose to ensure uniform distribution throughout the suspension. Draw immediately after shaking and administer promptly. Some researchers find injectable Winstrol suspension more painful at the injection site than oil based compounds, warming the vial and injecting slowly through a 23–25 gauge needle can help minimize discomfort.
Injectable Stanozolol has a half-life of approximately 24 hours typically administered once daily in research protocols. At 50mg/mL, a 1mL daily injection delivers 50mg per day, the most common research dose for Stanozolol. This 10mL vial at 50mg/mL contains 500mg total; sufficient for 10 days of daily 50mg administration. Some research protocols use every other day administration at 50–100mg per injection to reduce injection frequency while maintaining adequate plasma Stanozolol levels.
Yes! This F-40 Biotech batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 50mg/mL and compound identity as Stanozolol. A certificate of analysis is available.
