Nandro Phenylpropionate injection by CoreLabs

• Effective substance: nandrolone phenylpropionate,
• Content: 150mg/ml
• Vial with: 10ml
• Known as: NPP

Nandrolone Phenylpropionate (NPP) by CoreLabs is a fast-acting injectable anabolic steroid favored for its ability to promote lean muscle mass and enhance recovery without the long-term water retention often seen with slower-acting Nandrolone esters.

CoreLabs is known for providing high-concentration formulations, often catering to advanced users and athletes who require specific dosing schedules.

Product Specifications

• Active Ingredient: Nandrolone Phenylpropionate
• Standard Concentration: Often found in 100 mg/mL or 150 mg/mL strengths.
• Base: Oil-based solution for intramuscular administration.
• Ester Profile: The Phenylpropionate ester is much shorter than the Decanoate ester, leading to a rapid release of the hormone into the bloodstream.

 Functional Benefits

• Rapid Muscle Accretion: Accelerates protein synthesis and significantly improves nitrogen retention within the muscles.
• Enhanced Recovery: Drastically reduces recovery time between intense training sessions by repairing damaged muscle tissue and reducing inflammation.
• Joint Lubrication: Increases synovial fluid and collagen synthesis, which helps cushion joints and alleviate pain caused by heavy lifting.
• Low Estrogenic Activity: It carries a lower risk of bloating and "wet" gains compared to Deca-Durabolin, making it suitable for both cutting and lean bulking phases.

 Administration and Half-Life

• Active Half-Life: Approximately 2.5 to 3 days.
• Injection Frequency: To keep hormone levels stable, injections are typically performed every other day (EOD) or at least three times per week.
• Common Dosage (Men): Usually ranges between 200 mg and 500 mg per week.
• Common Dosage (Women): Generally kept very low, around 25 mg to 50 mg per week, to monitor for virilization.

 Potential Side Effects

• Progestogenic Side Effects: As a 19-nor compound, it can increase prolactin levels, which may cause gynecomastia or erectile dysfunction if not managed with ancillary medications (like Cabergoline).
• Testosterone Suppression: Like all Nandrolone variants, NPP is highly suppressive. Natural testosterone production will likely drop to near zero during use, necessitating a proper Post-Cycle Therapy (PCT).
• Cardiovascular Impact: It can lead to a decrease in HDL (good cholesterol) and an increase in LDL (bad cholesterol).
• Androgenic Risks: Although lower than testosterone, it can still cause acne, oily skin, and hair loss in those sensitive to these effects.
