Nandrolone Phenylpropionate (NPP) is an anabolic steroid used for muscle growth and recovery. It’s typically injected every other day due to its short ester. A common dosage ranges from 100–200 mg per injection, with cycles lasting 8–12 weeks. Always use sterile injection techniques and monitor for side effects like water retention or hormonal imbalances. Post-cycle therapy (PCT) is essential to restore natural testosterone. Consult a healthcare professional before use. Avoid if drug-tested.
