Deca 200 / NPP 150

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:

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

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

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).
