Dexadur 400 is an ultra-high-concentration injectable anabolic steroid produced by Thaiger Pharma. Packaged as a box of 10 individual 1ml single-use glass ampoules, each ampoule delivers a potent 400mg/ml concentration of Nandrolone Decanoate (widely recognized under the legendary brand name Deca-Durabolin).
Formulated at nearly double the standard market strength ($250\text{mg/ml}$), Dexadur 400 provides high-dose efficiency in a compact liquid volume. Belonging to the 19-nortestosterone (19-nor) family, Nandrolone Decanoate is celebrated for driving high-yield muscle mass growth, boosting red blood cell production, and providing exceptional joint relief and collagen synthesis. Single-use glass ampoules ensure pharmaceutical-grade sterility, precise unit dosing, and zero risk of rubber stopper contamination.
