Dragon Pharma Deca 500 – High-Dose Nandrolone Decanoate for Bulking Power
Deca 500 by Dragon Pharma delivers a potent dose of Nandrolone Decanoate at 500 mg/mL in a 10 mL vial, ideal for bodybuilders seeking serious mass-building potential. This long-acting injectable steroid is known for its muscle-preserving, joint-soothing, and performance-enhancing effects.
Nandrolone Decanoate is a widely studied anabolic compound with documented clinical and performance applications.
Why Use Deca 500?
Unlike lower-dose versions, Deca 500 offers enhanced anabolic response per injection — reducing overall injection frequency while still maintaining stable blood levels. This makes it convenient for users on high-volume bulking cycles or seeking hormone replacement benefits from fewer pins.
With its powerful anabolic-to-androgenic ratio and long ester half-life (~15 days), Deca 500 supports lean muscle gain, collagen synthesis, and improved recovery time.
Typical Dosage and Administration
- Beginner–Intermediate: 250–500 mg/week (split into 1–2 injections)
- Advanced users: Up to 750 mg/week (with regular health monitoring)
Due to its suppressive effect on testosterone production, Deca should always be paired with a test base like Testosterone Enanthate or Cypionat 250 to maintain hormonal balance.
Cycle Example with Deca 500
- Weeks 1–12: Deca 500 @ 500 mg/week
- Weeks 1–12: Testosterone Enanthate @ 500 mg/week
- Weeks 9–14: Clomid or Nolvadex for PCT
You can order all injectables, PCT agents, and support gear from our trusted Dragon Pharma steroid supplier — with verified batches and fast USA shipping.
Benefits of Deca 500
- Enhanced nitrogen retention and muscle repair
- Improved joint comfort due to collagen support
- Minimal liver strain
- Great for offseason mass or long TRT-style cruising
Potential Side Effects
Although well-tolerated by many, higher-dose Nandrolone cycles may lead to:
- Testosterone suppression (“Deca dick” if no test base used)
- Fluid retention
- Lower libido and mood changes
- Androgenic side effects (acne, oily skin)
Estrogenic side effects are typically mild but may require AI use in sensitive users. Regular blood work is advised.
The chemical structure, pharmacodynamics, and bioavailability of Nandrolone Decanoate are well detailed on PubChem.
Post-Cycle Therapy (PCT)
- Clomid: 50 mg/day for 4 weeks
- Nolvadex: 20 mg/day for 4 weeks
- HCG may be added mid-to-late cycle at 500 IU 2x/week
Lab-Tested for Purity
