Duraxyl 100

What is Duraxyl 100 (Nandrolone Phenylpropionate)?

Duraxyl 100 by Kalpa Pharmaceuticals is an injectable anabolic steroid containing Nandrolone Phenylpropionate (NPP). Known for its fast-acting properties compared to Deca-Durabolin (Decanoate), Duraxyl 100 delivers powerful anabolic effects with less water retention and shorter detection times. It is popular among athletes who want quality lean gains, improved recovery, and joint relief while keeping cycles flexible and manageable.

Main Effects

• Supports steady lean muscle growth
• Improves recovery and reduces joint pain
• Delivers fast-acting anabolic results
• Less water retention compared to Deca
• Enhances endurance and workout capacity

How Bodybuilders Use It

Duraxyl 100 is typically dosed at 300–600mg per week, split into injections every other day due to the short ester. Cycle length usually runs 8–10 weeks, making it suitable for athletes who prefer faster cycles with quicker recovery between runs. Its anabolic nature makes it versatile for both bulking and lean mass phases.

Recommended Stacks

• Duraxyl 100 + Testoxyl Propionate 100 for short lean bulk cycles
• Duraxyl 100 + Boldaxyl 300 for size and vascularity
• Duraxyl 100 + Dianoxyl 20 for explosive mass gains
• Duraxyl 100 + Masteroxyl 100 for lean and dry look
• Duraxyl 100 + Sustaxyl 350 for balanced performance

Side Effects and Control

Duraxyl 100 may cause estrogen-related issues such as water retention and gyno, though at a lower rate than Deca. Managing estrogen with Arimixyl or Aromaxyl and supporting prolactin levels with proper supplements helps keep the cycle balanced and safe.
