Some bodybuilders and athletes use trenbolone for its muscle-building and otherwise performance-enhancing effects. [ citation needed ] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone as a Schedule III controlled substance under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , metenolone , and trenbolone. 
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
Trenbolone enanthate is a long-acting injectable steroid with a great effect on protein metabolism. Trenbolone is one of the best effective anabolic compounds, promoting protein synthesis, as well as creating a positive nitrogen balance. It is an appetite stimulant and improves the conversion of proteins. In laboratory tests, it has been demonstrated that trenbolone increases protein and decreases fat deposition. It has proven to be an excellent product for promoting size and strength in the presence of adequate protein and calories, promotes body tissue building processes, and can reverse catabolism. Due to its particular ester, trenbolone enanthate is slower-acting than trenbolone acetate and faster acting than trenbolone hexahydrobenzylcarbonate. Based on its molecular structure, trenabol enanthate is theoretically stronger than either trenbolone acetate or trenbolone hexahydrobenzylcarbonate.
