Description
Pheno-NPP 100mg/ml
Pheno-NPP 100mg/ml (Nandrolone Phenylpropionate) is an injectable anabolic steroid derived from nandrolone. It is known for its faster release compared to Nandrolone Decanoate, making it a preferred option for users seeking quicker results in muscle development and physique conditioning. It possesses both anabolic and androgenic properties.
How It Works
Pheno-NPP supports muscle growth by enhancing protein synthesis, allowing muscle cells to retain more protein for development and recovery. It also has moderate androgenic activity, which helps preserve lean muscle mass during calorie restriction.
Compared to longer-acting nandrolone esters, it produces less water retention, making it more suitable for physique-focused or competition preparation phases.
Due to its shorter ester, it requires frequent administration to maintain stable blood levels. Detection in the body may persist for an extended period after use.
Proper Use and Dosage
To maintain consistent hormone levels, injections are typically spaced at regular intervals.
- Men: 300–600 mg per week
- Women: 50–100 mg per week, divided every 2–3 days
Dosage should always be adjusted carefully based on experience, goals, and tolerance.
Benefits
Pheno-NPP has been used in both medical and performance settings. In clinical use, nandrolone compounds may help prevent muscle wasting conditions such as those seen in chronic illness.
Potential benefits include:
- Support for lean muscle growth
- Improved recovery and reduced muscle breakdown
- Possible joint comfort through collagen support
- Lower water retention compared to longer-acting nandrolone esters
- Maintenance of muscle mass during dieting phases
Side Effects
Possible side effects may include:
- Suppression of natural testosterone production
- Cardiovascular strain (cholesterol and blood pressure changes)
- Water retention (less than longer esters but still possible)
- Acne and oily skin
- Sleep disturbances
- Gastrointestinal discomfort (e.g., nausea, diarrhea)
- Hormonal imbalance leading to elevated estrogen-related effects
- Virilization in females (deepened voice, body hair growth, etc.)
