Boldenone Undecylenate – Long-Acting Anabolic Steroid for Lean Mass, Vascularity & Endurance
Boldenone Undecylenate, commonly known by its trade name Equipoise (EQ), is a slow-acting injectable anabolic steroid designed to promote steady lean muscle development, increase vascularity, and enhance muscular endurance. Originally developed for veterinary use, Boldenone has become a favorite in the bodybuilding world due to its mild androgenic profile, low water retention, and versatile stacking compatibility.
With a long ester (undecylenate), Boldenone offers a half-life of approximately 14 days, making it ideal for extended cycles and those looking to build quality mass over time without excessive bulking or bloating.
Key Benefits

Scientific Profile
Boldenone Undecylenate is a modified version of testosterone with a structural change that reduces its androgenic strength while maintaining anabolic benefits. It binds to androgen receptors, stimulating protein synthesis, increasing nitrogen retention, and supporting muscle hypertrophy.
Additionally, it stimulates erythropoiesis (red blood cell production), making it ideal for athletes requiring enhanced stamina, recovery, and muscle oxygenation during high-volume training.

Boldenone Undecylenate is not fast-acting. It builds results slowly and steadily, which makes it a great base compound for long-term lean bulking or recomposition goals. It stacks extremely well with Testosterone Enanthate, Trenbolone, or Anavar for clean gains, strength, and vascularity.
