Boldenone 400 is an ultra-high-concentration injectable anabolic-androgenic steroid (AAS) manufactured by LA Pharma S.R.L., delivering a heavy 400mg/ml concentration of Boldenone Undecylenate in a 10ml multi-dose vial (4,000mg total active compound). Boldenone Undecylenate is globally recognized under its original trade name Equipoise (EQ).

Formulated at nearly double the standard market concentration ( $250\text{mg/ml}$ ), LA Pharma’s 400mg/ml variant is engineered for high-dose efficiency—allowing users to deliver substantial weekly amounts of Boldenone in significantly smaller injection volumes. Derived from testosterone, Boldenone delivers clean, quality muscle building, strong red blood cell elevation, and enhanced vascularity with low estrogenic activity.

Key Benefits & Applications

Ultra-High Concentration Volume Efficiency: Packing 400 mg into every 1 mL allows high-dose weekly protocols (e.g., 600 mg to 800 mg) to be achieved in tiny liquid volumes (1.5 mL to 2 mL total per week).
Steady, Dry Muscle Accretion: Drives consistent nitrogen retention and protein synthesis without heavy fluid retention or bloating, yielding firm, dense muscle mass.
Massive Erythropoietin (EPO) & Stamina Boost: Strongly stimulates red blood cell production, maximizing intramuscular oxygen delivery, delaying fatigue during exertion, and producing dramatic vascularity.
Appetite Stimulation: Renowned for significantly stimulating appetite, aiding individuals who need high caloric intake during long lean-gaining phases.
Multi-Dose Vial Versatility: Rubber-stoppered vial allows for micro-dosing and precise volume draws using standard syringes.
