Deca 500

Nandrolone Decanoate — Deca 500 by Dragon Pharma

Deca 500 is Dragon Pharma's high-concentration formulation of injectable Nandrolone Decanoate — the same active substance and ester as Deca 300, delivered at 500mg/ml instead of 300mg/ml. Each 10ml vial in Dragon Pharma's MCT oil carrier allows advanced users to reach higher weekly doses with reduced injection volume.

What Is Deca 500?

Deca 500 contains Nandrolone Decanoate — the same long-ester 19-nor compound used in Deca 300 — at a higher 500mg/ml concentration. The pharmacology is identical to standard Nandrolone Decanoate: the Decanoate ester extends release over approximately 15 days, with the same anabolic activity, joint comfort associations and prolactin-related considerations as any other Nandrolone Decanoate product. The only practical difference between Deca 500 and Deca 300 is concentration — a given dose is delivered in a notably smaller injection volume at 500mg/ml.

Effects and Benefits

• Significant lean mass gains, often associated with steady, quality weight gain over an extended cycle
• Notable joint comfort benefits during high-volume training, linked to effects on collagen synthesis
• High concentration allows higher weekly doses without proportionally larger injection volumes
• Fewer total injections or smaller volumes required for the same weekly dose compared to Deca 300
• Long ester provides stable, sustained levels well suited to extended cycles

Dosage and Administration

With the same ~15-day half-life as standard Nandrolone Decanoate, Deca 500 is dosed on the same weekly or twice-weekly schedule, with blood levels building gradually over the first several weeks. The practical advantage of the 500mg/ml concentration becomes apparent at higher weekly doses — for example, a 1000mg/week protocol requires 2ml total per week at 500mg/ml versus 3.3ml at 300mg/ml.
