Deca 500 by Dragon Pharma
What Is Deca 500?
Deca 500 is Dragon Pharma nandrolone decanoate at 500 mg per mL - the high-concentration version of the classic Deca-Durabolin. One 10 mL vial holds 5,000 mg, the highest-dose deca in the line.
High concentration means practical advantages for the advanced mass cycle: a full 500 mg dose is exactly 1 mL, and a 600 mg week is barely over a milliliter. Fewer injections, smaller volumes, same proven nandrolone - steady mass, recovery and joint relief on a serious bulking cycle.
Deca 500 Dosage
At 500 mg/mL the math is clean: 1 mL is a full 500 mg. High-dose mass protocols are the natural use for this concentration.
| Level | Weekly Dose | Per Injection (2x) |
|---|---|---|
| Classic mass | 500 mg | 0.5 mL |
| High dose Common | 750-1,000 mg | 0.75-1.0 mL |
Bloodwork Guidance
One 10 mL vial at 750 mg weekly lasts about 6-7 weeks. Advanced territory - only for experienced users with bloodwork.
Deca 500 Stacks
Nandrolone always sits on a testosterone base. Partners from the same Dragon Pharma line:
| Stack | Goal |
|---|---|
| Deca 500 + Enanthate 250 or Cypionat 250 | Testosterone base, equal or higher |
| Deca 500 + Dianabol 50 | Heavy oral kickstart |
| Deca 500 + Arimidex | Estrogen control on high-dose cycles |
Deca 500 Side Effects
Same nandrolone profile as lower-dose deca - but higher doses amplify everything, including the risks.
- Estrogen - more nandrolone, more aromatization; AI discipline matters.
- Prolactin - progestin effects grow with dose.
- Blood pressure and hematocrit - monitor closely at 750 mg+.
- Suppression - total; full PCT about 3 weeks after the last shot.
- Libido - keep the test base strong; deca without test is a mistake at any dose.

High-dose mass cycles: nandrolone for steady size, recovery and joint support on a serious bulking protocol. It is advanced territory - experienced users with bloodwork, always on a test base.
How much Deca 500 should I take?
The high-dose range is 500-1,000 mg weekly - 0.5-1.0 mL twice a week. At those doses, estrogen, prolactin and blood pressure management are mandatory.
How long does one vial of Deca 500 last?

Do I need a testosterone base with Deca 500?
Yes - at high nandrolone doses a strong test base matters even more. Keep testosterone at least equal to the deca dose to protect libido and estrogen balance.
When do I start PCT after Deca 500?
Decanoate clears slowly, especially after high doses. Start PCT about 3 weeks after the last injection and run SERMs until bloodwork confirms recovery.
