Rexogin is Alpha Pharma's name for stanozolol in injectable form, boxed as ten ampoules at 50 mg per millilitre. Alpha Pharma runs one of the more elaborate anti-counterfeit systems in this trade, with holographic stickers and a scratch-off code on the carton that can be verified on the manufacturer's own site.
The compound is a DHT-derived anabolic and does not aromatise. Unlike most injectables it is water-based rather than oil-based, so the suspension is noticeably thin and the micronised powder settles in the glass when the ampoule has been standing.
