Duraxyl 100 mg – Fast-Acting Nandrolone for Muscle Growth
Active Ingredient: Nandrolone Phenylpropionate
Manufacturer: Kalpa Pharmaceuticals
Pack Size: 10 mL Vial (100 mg/mL)
Duraxyl 100 mg contains Nandrolone Phenylpropionate (NPP), a fast-acting anabolic steroid known for its ability to support lean muscle growth, reduce joint discomfort, and promote overall recovery. Manufactured by Kalpa Pharmaceuticals, this compound is a shorter-ester version of Deca-Durabolin (Nandrolone Decanoate) with a quicker onset of action.
This makes Duraxyl a favorite among bodybuilders who want to benefit from Nandrolone's anabolic properties without the long detection times or extended estrogenic effects associated with longer esters.
The typical dosage of Duraxyl 100 mg is 200–400 mg per week, split into injections every 2–3 days due to the short ester. Users often stack it with Testosterone Propionate for synergistic effects or Oxymetholone during a bulking cycle.
