Nandrolone decanoate Vial

What is nandrolone decanoate

Nandrolone decanoate, often known by the trade name Deca-Durabolin, is a long-acting anabolic steroid used medically for treating anemia, osteoporosis, and muscle-wasting conditions.

In sports and bodybuilding, it is recognized for its ability to promote steady muscle growth, improve joint health, and enhance recovery without severe androgenic side effects.

Its decanoate ester ensures a slow, sustained release of nandrolone into the bloodstream, allowing less frequent injections and a more stable anabolic environment.

Because of its mild nature and strong anabolic potential, nandrolone is a foundation compound in many bulking and recovery-oriented cycles.

Main effects of nandrolone decanoate

💪 Promotes gradual, high-quality muscle mass gain

⚖️ Improves nitrogen retention and protein synthesis

🦴 Strengthens bones and connective tissues

🩸 Increases red blood cell production and endurance

💧 Reduces joint discomfort and inflammation

🧠 Enhances recovery and physical performance

How to take nandrolone decanoate

Administration

• Route: deep intramuscular injection
• Frequency: once every 7–10 days
• The long decanoate ester ensures prolonged anabolic activity and stable hormone levels

Dosage

• Beginner: 200–300 mg per week
• Intermediate: 400–600 mg per week
• Advanced: up to 800 mg per week (short cycles only)
• Typical cycle duration: 10–14 weeks

Nandrolone decanoate is often stacked with testosterone enanthate or cypionate for balanced anabolic and androgenic activity.

It may also be combined with methenolone or boldenone in lean bulking or recovery-focused programs.

Possible side effects

• Temporary suppression of natural testosterone
• Water retention or bloating at higher doses
• Possible decrease in libido during prolonged use without testosterone support
• Acne or oily skin (mild androgenic)
• Increased prolactin levels in sensitive users

Contraindications

• Prostate or breast carcinoma in men
• Severe liver, kidney, or heart dysfunction
• Pregnancy or breastfeeding
• Hypersensitivity to nandrolone or the carrier oil

How to store

• Store at 20–25 °C (68–77 °F) in a dry, dark place
• Protect from sunlight and heat sources
• Do not freeze
• Keep tightly sealed when not in use

How does nandrolone decanoate work

Nandrolone binds to androgen receptors in muscle and bone tissue, stimulating protein synthesis and nitrogen retention, which are essential for tissue growth and recovery.

It also enhances collagen synthesis and mineral retention, supporting joint health and bone strength.

Unlike testosterone, nandrolone converts to dihydronandrolone (DHN) rather than DHT, making it less androgenic and more tolerable for many users.

Additionally, it boosts erythropoiesis — the production of red blood cells — improving oxygen transport and endurance.

This combination of steady anabolic effect, minimal androgenic stress, and recovery enhancement makes nandrolone decanoate one of the most versatile and respected compounds in both medical and athletic settings.
