Nandrolone phenylpropionate 100mg/ml 10ml vial

Description

Nandrolone, also known as 19-nortestosterone, is a naturally occurring anabolic steroid in humans during intense physical exertion or pregnancy. Its primary metabolite, 19-norandrosterone, is found in urine in trace amounts.

🧬 Structure and Function:
Nandrolone differs from testosterone by lacking a carbon atom at the 19th position, which makes it structurally closer to progestins. This results in less androgenic activity compared to testosterone, but it can still cause unique side effects due to its interaction with progesterone receptors.

How Nandrolone Works

Unlike testosterone, which converts into dihydrotestosterone (DHT) via the enzyme 5-alpha reductase, nandrolone is converted into dihydronandrolone, a much milder androgen. This makes nandrolone suitable for male athletes concerned with prostate health.

💡 Low androgenic activity means fewer side effects like acne, hair loss, and body hair growth, which only become noticeable with excessive dosages.

Estrogenic Activity

Nandrolone has a 6-fold lower tendency to convert into estrogens than testosterone, without the involvement of aromatase. As a result, estrogenic side effects like gynecomastia and fluid retention are minimal, only appearing at extremely high dosages.

Key Benefits

✔ Significant muscle growth with minimal post-cycle loss
✔ Strengthening of bones and ligaments
✔ Accelerated skin regeneration and collagen synthesis
✔ Joint pain relief due to increased synovial fluid production
✔ Enhanced red blood cell production, improving oxygen transport and endurance
✔ Immune system fortification, particularly for AIDS patients
✔ Efficient absorption of amino acids and vital nutrients

Potential Adverse Effects

❌ Progestin activity may bind to progestin receptors, leading to: • Increased prolactin levels
• Suppressed gonadotropic hormones, reducing endogenous testosterone production
• Fat accumulation and rare gynecomastia

❌ Other side effects:
• Increased blood pressure
• Abdominal discomfort
• Mood fluctuations, headaches, and depressive tendencies
• Rare cases of severe headaches, pronounced back pain, and gynecomastia

Suggested Dosage

• Elderly patients for joint relief and bone strength: 50-150 mg weekly for 5-10 weeks
• For muscle mass enhancement: 200-800 mg weekly, with a typical regimen of 400 mg nandrolone and 500 mg testosterone weekly.

Pharmacokinetic Profile

✔ Half-life: 2-4 days
✔ Administration frequency: Bi-weekly

Nandrolone phenylpropionate, with its shorter half-life, is suitable for shorter bulking cycles. A standard cycle lasts 8-10 weeks. Experienced athletes may extend cycles up to six months, gradually increasing the dosage. Beginners should limit their cycles to 8 weeks without adjunct medications. For extended cycles, chorionic gonadotropin (hCG) is recommended. If hCG is not used during the cycle, it should be administered post-cycle and before post-cycle therapy (PCT).

Pharmaceutical Formulation

An oily solution for intramuscular injections.

Contraindications

❌ Pregnancy
❌ Prostate or breast cancer (suspected or confirmed)
❌ Lactating women
❌ Sensitivity to the active ingredient or any adjunct ingredients
❌ Elevated serum calcium levels

Storage Guidelines

• Store out of children’s reach.
• Keep in a cool, dry environment, away from direct sunlight.
• Maintain at ambient room temperature.
• Do not use past the expiration date.

Nandrolone is a highly effective anabolic steroid for muscle growth and strength enhancement with minimal estrogenic side effects, making it a top choice for both bodybuilders and athletes. Always consult with a healthcare professional before starting any supplementation to ensure safe and effective use.
