DURABOLIN-NPP (Nandrolone Phenylpropionate) 100mg/ml  | XT Labs

Active Substance: Nandrolone Phenylpropionate (NPP)
Manufacturer: XT Labs
Pack: 10ml Vial (100mg/ml)
Form: Injectable Solution

Overview

DURABOLIN-NPP by XT Labs contains Nandrolone Phenylpropionate (NPP) — a fast-acting anabolic compound belonging to the 19-nor family of steroids. It shares the same base hormone as Nandrolone Decanoate (Deca-Durabolin) but with a shorter ester, resulting in quicker release, faster action, and shorter detection time.

NPP was one of the earliest anabolic steroids developed for medical use, prized for its muscle-building, joint-protective, and recovery-enhancing properties. In the bodybuilding world, it’s favored for producing lean muscle gains, improved endurance, and strength enhancement, all while being well-tolerated with mild androgenic effects.

Chemical and Biological Profile

• Androgenic Rating: 37 (moderate)

• Anabolic Rating: 125 (strong)

• Chemical Name: 19-norandrost-4-en-3-one-17β-ol

• Estrogenic Activity: Low

• Progestational Activity: Moderate

Nandrolone is a naturally occurring metabolite found in trace amounts in the human body (less than 0.4 mg/ml). The phenylpropionate ester version provides a rapid onset and shorter duration than its decanoate counterpart, making it ideal for users seeking fast, controllable results.

How DURABOLIN-NPP Works

Nandrolone Phenylpropionate acts as a powerful anabolic agent that enhances protein synthesis, nitrogen retention, and red blood cell production. These effects combine to create an optimal environment for muscle growth and recovery.

Key Mechanisms:

• Protein Synthesis: Increases the rate of protein creation within muscle cells for faster repair and growth.

• Nitrogen Retention: Maintains a positive nitrogen balance, essential for an anabolic state.

• Erythropoietin Stimulation: Enhances red blood cell production, improving oxygen delivery and endurance.

• Joint and Tissue Health: Promotes collagen synthesis and fluid retention in joints, reducing pain and stiffness during heavy training.

• Lean Mass Gains: Provides steady, high-quality muscle growth without excessive fat or water retention.

Compared to Deca-Durabolin, NPP acts faster, peaks within 24–48 hours, and has an active life of about one week, allowing more precise control over hormone levels.

Benefits of DURABOLIN-NPP

• Rapid onset of anabolic activity (visible results within 1–2 weeks)

• Lean, high-quality muscle gains without excessive bloating

• Enhanced recovery and endurance between training sessions

• Improved joint comfort and mobility

• Low estrogenic side effects due to minimal aromatization

• Increased strength and stamina during resistance training

Because of its mild androgenic profile, NPP is often chosen by both male and female athletes seeking clean, steady progress with fewer side effects.

Dosage and Administration

Recommended Dosage:

• Men: 200–400 mg per week for 10–12 weeks

• Women: 50–100 mg per week for 6–8 weeks

Injection Frequency:
Due to its short half-life, NPP should be injected every 3–5 days to maintain stable hormone levels.

Example Protocol:

• Week 1: 200 mg

• Week 2–12: 400 mg weekly, divided into 2–3 injections

Cycle Stacking:
For optimal results, DURABOLIN-NPP can be combined with:

• Testosterone Propionate or Enanthate for hormonal support

• Winstrol or Anavar for lean cutting cycles

• Dianabol for bulking and strength phases

Always include Post-Cycle Therapy (PCT) after any Nandrolone cycle to restore natural testosterone production.

Side Effects of DURABOLIN-NPP

Nandrolone Phenylpropionate is known for being mild and well-tolerated, but side effects can still occur, especially at higher doses or with prolonged use.

Possible Side Effects:

• Mild androgenic effects (acne, hair growth, oily skin)

• Increased libido (occasionally excessive)

• Headache or nasal congestion (rare)

• Water retention (minimal, dose-dependent)

• Tension or irritability

• Nosebleeds (rarely reported)

Estrogenic Effects: Rare, but may include slight water retention or gynecomastia in sensitive users.
If symptoms occur, Tamoxifen (Nolvadex) or an aromatase inhibitor (AI) like Anastrozole (Arimidex) may help.

Progestogenic Effects:
As a 19-nor compound, NPP can mildly elevate prolactin levels. Use Cabergoline or Pramipexole if prolactin-related issues arise.

Summary

DURABOLIN-NPP (Nandrolone Phenylpropionate) from XT Labs is a high-quality, short-acting anabolic compound that offers fast lean muscle gains, improved strength, and enhanced recovery without excessive water retention or severe side effects.

Its short ester structure ensures faster release, making it easier to control, adjust, and recover from compared to longer esters like Deca-Durabolin. Ideal for athletes seeking controlled, effective, and clean results, NPP remains one of the most reliable injectables for building dense, high-quality muscle mass.
