Trenbolone is an androgen and anabolic steroid (AAS) of the nandrolone group which itself was never marketed. Trenbolone acetate is used in veterinary medicine in livestock to increase muscle growth and appetite
Trenbolone has both anabolic and androgenic effects. Once metabolized, trenbolone esters have the effect of increasing ammonium ion uptake by muscles, leading to an increase in the rate of protein synthesis. It may also have the secondary effects of stimulating appetite and decreasing the rate of catabolism, as all anabolic steroids are believed to; however, catabolism likely increases significantly once the steroid is no longer taken.
Veterinary
Trenbolone, as trenbolone acetate, improves muscle mass, feed efficiency, and mineral absorption in cattle
Side effects
Sometimes human users may experience an event called “tren cough” shortly after or during an injection, where the user experiences a violent and extreme coughing fit, which can last for minutes.
