Deca Durabolin 400 by Meditech Human Pharmaceuticals is an ultra-high-concentration injectable anabolic steroid containing Nandrolone Decanoate at a heavy density of 400mg/ml in a 10ml multi-dose vial (4,000mg total active compound). Nandrolone Decanoate is globally celebrated as one of the most reliable and effective anabolic compounds for physical conditioning, tissue preservation, and strength development.

Belonging to the 19-nortestosterone (19-nor) family, Meditech’s 400mg/ml formulation is engineered for maximum volume efficiency—allowing advanced users to administer substantial weekly dosages in minimal injection fluid volumes. It combines strong anabolic activity with low androgenicity, reduced estrogenic conversion, and significant therapeutic benefits for joint collagen synthesis and skeletal recovery.

Key Benefits & Applications

Ultra-High Concentration Efficiency: Delivers a heavy 400 mg dose per 1 mL, allowing users running higher-dose protocols (e.g., 400 mg to 800 mg per week) to significantly reduce total liquid injection volume.
Exceptional Joint & Tendon Relief: Promotes type I collagen synthesis, mineral retention, and synovial fluid production in joint capsules, providing substantial relief from heavy training wear and tendonitis.
Dense Muscle Mass & High Nitrogen Retention: Triggers high-level muscle protein synthesis and exceptional intramuscular nitrogen storage for solid, high-yield tissue gains.
Enhanced Erythropoiesis & Oxygen Transport: Stimulates renal erythropoietin (EPO) production, expanding red blood cell volume to delay fatigue, improve stamina, and accelerate recovery between sessions.
Low Conversion to Estrogen: Converts to estrogen at only a fraction of testosterone’s rate, minimizing severe fluid accumulation and blood pressure spikes under moderate dosages.
