Trenace pro 100 is an oil based solution of trenbolone acetate for IM injection. Trenbolone is an anabolic steroid with significant anabolic and androgenic effects. The fast acting ester produces a rapid increase in serum trenbolone levels which remain elevated for 3-4 days thereafter. Trenbolone promotes significant increases in strength, muscle anabolism, appetite and aggression, and has been demonstrated to reduce body fat.
