Dragon Pharma Deca 500 is one of the most concentrated Nandrolone-based injectables available, delivering 500 mg/mL of pharmaceutical-grade Nandrolone Decanoate. This high-dosage formulation is ideal for experienced users looking to minimize injection volume while maximizing muscle recovery, strength, and joint support.
Nandrolone Decanoate is a time-tested anabolic steroid known for its ability to support lean muscle growth, increase red blood cell count, and accelerate joint repair. Dragon Pharma's Deca 500 formulation offers a powerful solution for advanced athletes needing enhanced anabolic effects without increasing injection frequency.
According to PubMed clinical research, Nandrolone promotes positive nitrogen balance and supports collagen synthesis, making it highly beneficial in both performance and recovery cycles.
Nandrolone is a 19-nortestosterone derivative with a favorable anabolic to androgenic ratio. The decanoate ester provides a slow and sustained release, maintaining stable blood levels with fewer injections. Users report increased endurance, muscle fullness, and decreased post-workout joint pain, especially in high-volume training scenarios.
Independent lab analysis from September 2021 verified the potency of Dragon Pharma Deca 500, confirming a content of 492.09 mg/mL. This ensures users receive full-strength, correctly dosed product in every vial.
With 500 mg/mL concentration, users can inject as little as 1 mL per week to achieve strong anabolic support. However, due to pip (post-injection pain) at high concentrations, it is recommended to split the dosage into 2 x 0.5 mL injections or dilute with another compound like Test Cypionate.
Cycle durations typically range from 10–14 weeks. Because Deca suppresses natural testosterone production, it is essential to stack with a base such as Test Enanthate.
Deca 500 is best suited for bulking or off-season growth phases. Popular stacks include:
Although Nandrolone does not convert heavily to estrogen, it does have progestogenic effects which can contribute to water retention and potential gynecomastia. To mitigate this, some users combine it with Arimidex or Femara and use Cabergoline to manage prolactin levels.
Other potential side effects at high doses may include increased blood pressure, reduced libido (if not stacked with testosterone), and suppressed HPTA function. Due to the high concentration, injection site discomfort can be more common if not dosed properly.
Deca 500 suppresses natural testosterone and may delay recovery without a proper PCT. Start post-cycle therapy 3 weeks after your last injection using Clomid or Enclomiphene, continuing for at least 4 weeks. Supplements that support liver and endocrine health may also be beneficial during recovery.

Yes. Due to its high concentration, Deca 500 is best suited for intermediate or advanced users who have prior cycling experience and understand how to manage side effects and injection volume.
Yes. Deca 500 can be mixed in the same syringe with other oil-based injectables like Testosterone Enanthate to reduce injection frequency and smooth out pip.
It may increase water retention due to mild estrogenic and progestogenic activity. Use of AI and prolactin management compounds can help minimize these effects.
Although it's long-acting, many users split the dose into 2 injections per week to improve comfort and maintain steady blood levels, especially at this concentration.
