Deca 200 / NPP 150 by Dragon Pharma
What Is Deca 200 / NPP 150?
This Dragon Pharma vial is a nandrolone blend: 200 mg of decanoate (Deca-Durabolin) plus 150 mg of phenylpropionate (NPP) per mL, 3,500 mg total in a 10 mL vial. Two esters of the same compound, one bottle.
Nandrolone is the classic mass builder - steady size, appetite, recovery and famously kind joints. The blend gives the best of both esters: fast-acting NPP for quick saturation, long decanoate for stable levels. One injection schedule covers both.
Deca 200 / NPP 150 Dosage
At 350 mg/mL, dosing is simple: a classic mass-cycle dose is 350-525 mg of nandrolone per week - 1 to 1.5 mL.
| Level | Weekly Dose | Per Injection (2x) |
|---|---|---|
| Moderate | 350 mg | 0.5 mL |
| Classic mass Common | 525 mg | 0.75 mL |
| Advanced | 700 mg | 1.0 mL |
Cycle Length
Two injections a week keep both esters stable. A 10 mL vial covers about 6-10 weeks depending on dose.
Deca 200 / NPP 150 Stacks
Nandrolone always runs on a testosterone base - never alone. Every partner below is Dragon Pharma, one source for the cycle.
| Stack | Goal |
|---|---|
| Deca/NPP + Enanthate 250 or Cypionat 250 | Testosterone base for mass |
| Deca/NPP + Dianabol 20 | Fast oral kickstart (first 4 weeks) |
| Deca/NPP + Arimidex | Estrogen control - nandrolone aromatizes |
Deca 200 / NPP 150 Side Effects
Nandrolone sides are well documented - most are manageable with proper cycle design.
- Estrogen - nandrolone aromatizes, so water retention and gyno risk exist; an AI is standard.
- Prolactin - progestin activity can raise prolactin at higher doses.
- Deca dick - the famous libido issue, usually from running nandrolone without enough testosterone or with estrogen crashed.
- Suppression - strong and long-lasting; full PCT is essential.
- Bloodwork - lipids and hematocrit mid-cycle.

What is Deca 200 / NPP 150?
It is a Dragon Pharma nandrolone blend: 200 mg of decanoate (Deca-Durabolin) and 150 mg of phenylpropionate (NPP) per mL, 3,500 mg per 10 mL vial.
What does Deca-Durabolin do?
Nandrolone is a classic mass builder: steady muscle gains, better appetite and recovery, and famously kind joints. It aromatizes less than testosterone but still needs estrogen management.
Is Deca a testosterone?
No - nandrolone is a different anabolic steroid, closely related to testosterone but with its own profile: more anabolic per androgen, less DHT conversion, and no direct estrogen pathway - it aromatizes to a weaker estrogen.
Why blend NPP with Deca?
NPP (phenylpropionate) is the fast ester - it saturates within days. Decanoate is the slow ester - it holds levels for weeks. The blend gives quick onset plus a long stable plateau in one vial.
How much Deca / NPP should I take?
At 350 mg/mL, a classic mass dose is 350-525 mg weekly - 0.5-0.75 mL twice a week. Nandrolone should never exceed your testosterone dose on cycle.
What is deca dick and how do I avoid it?
Deca dick is the libido and erection problem linked to nandrolone - usually from running it without enough testosterone or with estrogen crashed by too much AI. Keep testosterone equal or higher and estrogen in range.
Do I need PCT after Deca / NPP?
Yes - nandrolone suppresses natural testosterone strongly and the decanoate ester clears slowly. Start PCT about 3 weeks after the last injection, with SERMs such as clomiphene or tamoxifen.
