Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances 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 . 
Tri-Tren 150 is an injectable steroid, this drug contains Trenbolone Acetate, Hexahydrobenzylcarbonate and Enanthate and is made by Dragon Pharma , Europe.
Tri-Tren 150 is been formulated with three different esters: Trenabolone Accetate, Trenbolone Hexahydrobenzylcarbonate and Trenbolone Enanthate. The Acetate ester allows Tri-Tren 150 to display a rapid elevation of blood plasma levels of Trenbolone. The other two esters (Hexahydryobenzyclcarbonate and Enanthate), which release at differing but slower rates, prolong the blood plasma levels of trenbolone.
Regardless of the ester, Trenbolone is a very potent androgen with strong anabolic activity. It can be used for mass development or it can be used for cutting (which is more common) and is well suited for either. Due to its progestenal nature, Testosterone must always be stacked with it, although Trenbolone does not convert to estrogen.
Tri-Tren 150 would probably be used for cutting, and one would probably stack it with an anabolic such as Winstrol or Primobolan. Bulking with this steroid is also highly possible, and with the addition of compounds like Dianabol and Testosterone, quality muscle mass would be quickly accrued.
Q: I may compete in a tested federation in the next year, but I’m very interested in using Tri Tren. Any recommendations?
A: There are products from the likes of SteroidCleanse which will make everything but Nandrolone-based compounds disappear in less than a week. Use of these will make the five month detection window of Tri Tren seem like nothing to be concerned about. However, if you are competing in a bodybuilding or sports federation which also prohibits the use of masking agents, then Tri Tren may not be the right choice for you.
