Trenbolone is often touted as an anabolic steroid that has ‘harsh’ side effects and tends to frighten many individuals who are considering the use of this compound. First and foremost, it should be established that because Tren does not aromatize into Estrogen at any dosage, there is no risk for encountering Estrogenic side effects . The Trenbolone side effects of particular concern are its androgenic side effects, and other side effects that are not usually seen with any other anabolic steroids (such as insomnia, excessive sweating, etc.).
Finally, it must be mentioned that any particular ester of Trenbolone does not require a similarly estered anabolic steroid to be stacked with it (for example, Trenbolone Enanthate stacked with Testosterone Enanthate). It is a perfectly fine and safe practice to be able to combine, for example, Trenbolone Acetate and Testosterone Enanthate (instead of Testosterone Propionate ) in Trenbolone cycles. These combinations present no problems and actually work well, but every individual curious about these combinations must always be aware that proper timing, half-life, and injection frequency varies with each of these compounds. The only reason why many individuals prefer to stack Testosterone Enanthate with Trenbolone Enanthate , for example, is because of the convenience aspect and ease of administration frequency and timing (as both compounds are identical in half-life).
Testosterone enanthate ( USAN , BAN ) (brand names Delatestryl , Testostroval , Testro LA , Andro LA , Durathate , Everone , Testrin , Andropository ), or testosterone heptanoate , is an androgen and anabolic steroid and a testosterone ester .    Along with testosterone cypionate and testosterone propionate , it is one of the most widely used testosterone esters.  Testosterone enanthate was first introduced in 1952.  Administered via intramuscular injection , it is the most widely used form of testosterone in androgen replacement therapy .
