Decabol 250 by British Dragon delivers 250 mg/mL of Nandrolone Decanoate in a 10 mL vial, offering athletes a slow-acting, long-ester anabolic steroid ideal for bulking, joint support, and recovery enhancement. This compound is renowned for its ability to produce quality lean muscle gains while minimizing androgenic side effects.
British Dragon's reputation for high-purity injectable steroids makes Decabol 250 a go-to option for bodybuilders who value consistency, stability, and real performance. The long-acting decanoate ester allows for steady blood levels and reduced injection frequency—typically once or twice weekly.
Nandrolone Decanoate binds to androgen receptors to promote increased nitrogen retention, protein synthesis, and red blood cell production. These effects lead to muscle hypertrophy, faster recovery, and enhanced endurance. Additionally, Nandrolone is known for its joint-soothing effects, making it popular among powerlifters and injury-prone athletes.
As supported by clinical literature on nandrolone's efficacy, the compound has long-standing use in clinical medicine for anemia, osteoporosis, and muscle wasting—further reinforcing its effectiveness in sports performance contexts.
For performance enhancement, most users inject 300–600 mg/week, split into two doses for optimal plasma levels. Due to its long half-life, it can also be injected once per week without severe fluctuations.
Beginner cycles may include 300 mg/week for 10–12 weeks. More advanced users may increase to 600 mg/week and stack it with other anabolic compounds.
Decabol 250 works synergistically in bulking and mass-building stacks. Recommended combinations include:

Suppression of natural testosterone is significant after using Decabol 250. PCT should begin 2–3 weeks post-cycle and include:
