Nandrolone Dual-Ester Blend — Deca 200 / NPP 150 by Dragon Pharma
The Deca/NPP Blend is Dragon Pharma's formulation of two Nandrolone esters in a single 350mg/ml vial — Nandrolone Decanoate at 200mg/ml and Nandrolone Phenylpropionate at 150mg/ml. Unlike blends that combine different active compounds, this product combines two esters of the same molecule to engineer a specific release profile: NPP's faster onset layered beneath Deca's prolonged sustained release.

Why Two Esters of the Same Compound — The Release Engineering Logic
This blend is unique in the Dragon Pharma range — two esters of identical active compound combined to produce a release profile neither ester achieves alone. This is the Nandrolone equivalent of the multi-ester testosterone logic in Sustanon:
| Component | Amount | Half-Life | Role in Blend |
|---|---|---|---|
| Nandrolone Phenylpropionate (NPP) | 150 mg/ml | ~5 days | Faster onset — blood levels build within the first week; earlier joint comfort and anabolic effects |
| Nandrolone Decanoate (Deca) | 200 mg/ml | ~15 days | Sustained baseline — maintains elevated Nandrolone levels throughout the full cycle with less frequent contribution from the short ester |
The combined result: within the first 1-2 weeks, the NPP component produces a meaningful Nandrolone blood level while the Deca component is still building. By weeks 4-6, the Deca component has reached steady-state and becomes the dominant contributor. The blend therefore avoids the primary criticism of standalone Deca — that a 14-16 week cycle is required before full steady-state is achieved — while retaining Deca's sustained, stable long-term levels.
Quantified Onset Comparison
| Protocol | Meaningful blood levels by week... | Steady-state by week... | PCT start post-cycle |
|---|---|---|---|
| Standalone Deca only (~15 day t½) | Week 3–4 | Week 10–12 | 3–4 weeks post |
| Standalone NPP only (~5 day t½) | Week 1–2 | Week 3–4 | 10–14 days post |
| Deca/NPP Blend (this product) | Week 1–2 (NPP component) | Week 8–10 (Deca component) | 3–4 weeks post (Deca-governed) |
Important: PCT timing is governed by the longest ester present — the Deca component's ~15-day half-life means PCT cannot begin until 3-4 weeks after the last injection, the same as standalone Deca. The NPP component clears sooner, but the Deca component's ongoing suppression means waiting for it to clear before PCT can be effective.
Effects and Benefits
- Faster initial onset than standalone Deca — NPP component produces meaningful Nandrolone levels within the first 2 weeks
- Sustained, stable Nandrolone levels across the full cycle from the Deca component
- Joint comfort benefits from Nandrolone's collagen synthesis effects — present earlier than with standalone Deca due to NPP onset
- Lean mass gains with lower water retention than testosterone at equivalent doses
- High concentration (350mg/ml) reduces injection volume for the combined Nandrolone load
Dosage and Administration
| Experience Level | Weekly Dose | Frequency | Cycle Length |
|---|---|---|---|
| Intermediate | 350–525 mg/week (1–1.5ml) | Twice weekly | 12–16 weeks |
| Advanced | 525–700 mg/week (1.5–2ml) | Twice weekly | 12–16 weeks |
Twice-weekly injection provides stable combined blood levels — the NPP component's ~5-day half-life benefits from twice-weekly dosing, while the Deca component is stable on once or twice weekly. Splitting the weekly dose into two injections maintains tighter levels from both components simultaneously. At 350mg/ml, a 1ml twice-weekly injection delivers 700mg/week total Nandrolone (400mg Deca + 300mg NPP).
Side Effects
- Elevated prolactin from 19-nor activity — Cabergoline is commonly used; prolactin-related effects ("Deca dick") onset earlier than standalone Deca due to NPP component
- Suppression of natural testosterone — Post Cycle Therapy required; PCT timing governed by Deca ester — start 3-4 weeks after last injection
- Lower aromatisation than testosterone — estrogen management less critical, but possible at higher doses; Arimidex available if needed
- Very long detection window — Nandrolone metabolites detectable up to 18 months after last injection regardless of which ester was used
Deca/NPP Blend vs Standalone Products
- Deca/NPP Blend (this product) — faster onset than standalone Deca; sustained levels from the Decanoate component; one vial; twice-weekly injection
- Deca 300 (standalone) — simpler single-ester, predictable pharmacokinetics; weekly injection sufficient; for users not concerned about onset speed
- NPP 150 (standalone) — fastest Nandrolone onset; EOD injection required; suitable for shorter cycles where the Deca ester's slow build is a disadvantage
Building a Cycle Around the Deca/NPP Blend
- Enantat 250 or Cypionat 250 as the testosterone base — Nandrolone is not run alone
- Dianabol 20 as a short oral kickstart during the first weeks — the NPP component accelerates Nandrolone onset but a Dianabol kickstart still bridges the gap while both esters build
- Cabergoline for prolactin management throughout
- Clomid or Nolvadex for Post Cycle Therapy
"The Deca/NPP Blend combines two esters of the same Nandrolone molecule to produce a release profile neither ester achieves alone — the faster onset of NPP layered beneath the sustained, stable baseline of Deca, in a single high-concentration vial."
Storage and Handling
Store at room temperature away from direct sunlight and heat. Use sterile technique for every draw — a fresh needle for drawing and a separate needle for injection is recommended.
