Winstrol is the brand name of the anabolic steroid with the generic name stanozolol. It is a derivative of testosterone and FDA approved for human use. Besides its use by bodybuilders, it shows efficacy in treating anaemia and hereditary angioedema. It is often sold as an aqueous suspension that injects directly into the bloodstream. Although counterfeit versions are on the market, there are a few ways to distinguish the real thing from the imitation.
Check the size and shape of the ampoule. Injectable Winstrol is only sold in 1-milliliter containers. These ampoules also have an unusually large belly, unlike the narrow-bodied ampoules that many other drugs are sold in. Sometimes Winstrol from an Italian manufacturer, still distinct and authentic, is sold in a small vial with a lid.
Observe the consistency of the fluid. It should be a milky white suspension. Let it rest upright for several minutes. Has the active ingredient of the drug begun to settle in a crystalline precipitate at the bottom of the ampoule? This is a mark of authentic Winstrol. About 50 milligrams of the active ingredient should lie in a white layer at the bottom of the vial.
Check the inscription. Authentic Winstrol has either a brown inscription in Spanish or a blue inscription in Italian. You can feel the latter inscription with your finger.
