Nandrolone Decanoate (commonly referred to as Deca 200) is a long-acting injectable anabolic steroid known for its joint-supportive properties, muscle-building potential, and low androgenic profile. It is a widely used compound in both therapeutic and performance-enhancement settings due to its high anabolic ratio and relatively mild side effect profile.

Key Specs:
• Concentration: 200mg/mL
• Half-Life: ~6–12 days
• Administration: Intramuscular injection, typically 1–2× per week
• Anabolic/Androgenic Ratio: ~125:37
• Use Cases:
• Lean mass and strength gains
• Joint and connective tissue support
• Recovery enhancement
• Muscle preservation during caloric restriction
Mechanism of Action:
Nandrolone binds to androgen receptors, increasing protein synthesis, nitrogen retention, and red blood cell production. Unlike testosterone, it has minimal estrogenic conversion, but carries progestin activity, which may impact prolactin levels. It is known for promoting collagen synthesis and synovial fluid enhancement, contributing to perceived joint relief.
Typical Protocols:
• Performance Dosing: 200–400mg per week
• Cycle Duration: 10–16 weeks (standard)
• Stacking: Common with Testosterone (to prevent suppression side effects), EQ, or Dbol
• PCT: Required; suppresses natural testosterone production
• Side Effects: Possible water retention, libido suppression (if used without test), prolactin-related issues
• Support: Cabergoline or dopamine agonists (if prolactin-related sides emerge), estrogen control as needed
Note: Nandrolone is not recommended as a standalone cycle due to its suppressive nature and potential for sexual side effects. Best used in testosterone-supported cycles with proper monitoring and post-cycle therapy.
