Side effects of Trenbolone

Trenbolone is a steroid used on livestock to increase muscle growth and appetite. To increase its effective half-life, trenbolone is administered as a prodrug as an ester conjugate such as trenbolone acetate, trenbolone enanthate, or trenbolone cyclohexylmethylcarbonate. Plasma lipases then cleave the ester group in the bloodstream leaving free trenbolone.

Pharmacodynamics

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.At least one study in rats has shown trenbolone to cause gene expression of the androgen receptor (AR) at least as potent as dihydrotestosterone (DHT). This evidence tends to indicate trenbolone can cause an increase in male secondary sex characteristics without the need to convert to a more potent androgen in the body.

Studies on metabolism are mixed, with some studies showing that it is metabolized by aromatase or 5α-reductase into estrogenic compounds, or into 5α-reduced androgenic compounds, respectively.

Trenbolone has potency five times as high as that of testosterone.Trenbolone also binds with high affinity to the progesterone receptor,Trenbolone binds to the glucocorticoid receptor, as well.

Uses

Trenbolone, as trenbolone acetate, improves muscle mass, feed efficiency, and mineral absorption in cattle.

Side effects

Sometimes human users will 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.
