Androx 400 is a high-concentration, pharmaceutical-grade injectable testosterone formulation produced by Thaiger Pharma. Packaged as a box of 10 individual 1ml single-use glass ampoules, each ampoule delivers an exceptional total dose of 400mg/ml comprised of a synergistic multi-ester testosterone blend.

By combining short-, medium-, and long-acting testosterone esters in a single high-potency mixture, Androx 400 provides both an immediate surge in blood androgen levels and sustained release kinetics lasting over two weeks. Designed for serious tissue building, metabolic enhancement, and rapid physical conditioning, this high-density formulation minimizes total injection volume while maximizing circulating serum testosterone.

Key Benefits & Applications

High-Concentration Volume Efficiency: Delivers a heavy 400 mg dose in a single 1 ml volume, reducing total fluid volume needed for high-dose weekly protocols.
Multi-Phasic Release Profile: Short-acting esters provide rapid physiological onset within 24–48 hours, while longer esters maintain stable, elevated hormone levels for up to two weeks.
Substantial Muscle Hypertrophy & Power: Drives rapid increases in muscle protein synthesis, satellite cell activation, and total nitrogen retention for fast gains in size and physical strength.
Accelerated Recovery & Glycogen Storage: Boosts red blood cell production (erythropoiesis) and intracellular glycogen storage, enhancing muscle stamina, pump, and systemic recovery times.
Ampoule Sterility & Dosing Accuracy: Single-use glass ampoules eliminate degradation risks associated with rubber stoppers and ensure maximum sterility and concentration integrity per dose.
