What is Nandrolone Phenylpropionate (NPP)?
Nandrolone Phenylpropionate (NPP) is an anabolic steroid derived from 19-nortestosterone, known for its effectiveness in increasing muscle mass and reducing androgenic side effects compared to testosterone. Structurally similar to progestins, NPP has low androgenic activity, reducing the risk of acne, baldness, and excessive body hair growth. Unlike testosterone, it converts to dihydronandrolone, a very weak androgen, making it safer for men with prostate problems.

Main benefits of Nandrolone Phenylpropionate (NPP)

• Significant muscle growth: up to 8 kg in one cycle, with minimal reduction.

• Joint and bone support: promotes collagen synthesis, improves joint lubrication and reduces joint pain.

• Endurance and oxygenation: increased red blood cell production, improving oxygen transport and physical endurance.

• Reduction of estrogenic effects: low risk of gynecomastia and water retention even at high doses.

• Nutrient Absorption: Optimizes the assimilation of amino acids and essential nutrients.

Side Effects:
Despite its low androgenicity, Nandrolone Phenylpropionate (NPP) can interact with progestin receptors, increasing prolactin production and reducing endogenous testosterone production. Possible side effects include increased blood pressure, mild changes in body fat, rare cases of gynecomastia, headache, irritability, and depression.

Recommended dosages

• Medical use (joint pain, osteoporosis): 50-150 mg weekly for 5-10 weeks.

• Muscle gain: 200-800 mg per week; average dosage 400 mg, often combined with 500 mg of testosterone to improve results and reduce progestin effects.

Profile and administration

• Half-life: 2-4 days

• Frequency of injections: 2 times a week

• Pharmaceutical form: Oily solution for intramuscular injection.
  The typical cycle lasts 8-10 weeks, but can extend up to 6 months for advanced athletes. It is recommended to combine NPP with testosterone and, in long cycles, the use of hCG before the PCT.

Contraindications
Pregnancy, breastfeeding, known or suspected prostate or breast cancer, hypersensitivity to the active substance, high calcium levels in the blood.

Storage:
Store in a cool, dry place, away from direct sunlight, at room temperature. Keep out of reach of children. Do not use after the expiration date.
