Onyx Deca 250 is a premium injectable product containing 250 mg/ml of nandrolone decanoate in a 10 ml vial. Nandrolone decanoate is a long-acting anabolic compound that has historically been used in medical settings for conditions such as anemia, osteoporosis, and muscle-wasting disorders. Its extended release profile allows the active ingredient to remain effective for longer periods compared to shorter esters.

The decanoate ester slows the release of nandrolone into the bloodstream, providing prolonged activity and making it one of the most widely recognized long-acting injectable compounds. Medical references note that nandrolone decanoate has been used to support red blood cell production and bone health.

Each 10 ml vial delivers a concentration of 250 mg/ml in an oil-based solution, a format commonly found in similar nandrolone products.
