what is Trenbolone

Trenbolone is a steroid used by veterinarians on livestock to increase muscle growth and appetite. To increase its effective half-life, trenbolone is not used in an unrefined form, but is rather administered as ester derivatives such as trenbolone acetate, trenbolone enanthate or trenbolone cyclohexylmethylcarbonate (Parabolan). Plasma lipases then cleave the ester group in the bloodstream leaving free trenbolone.Trenbolone acetate is often referred to as "Fina" by users, because injectable trenbolone acetate was originally adapted for use by bodybuilders from dissolution of Finaplix H pellets, an ear implant used by cattle ranchers to maintain the weight of cattle during shipping to slaughter. Studies have shown that trenbolone improves muscle mass in cattle and also feed efficiency and mineral absorption.Trenbolone compounds have a binding affinity for the androgen receptor five times as high as that of testosterone. Once metabolized, the drugs have the effect of increasing nitrogen 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.
