There does not exist too much difference between the two previous steroidal cycles. The only major change is the addition of the very powerful injectable anabolic steroid Trenbolone. Trenbolone Enanthate in particular is chosen, in order to blend well with the other two anabolic steroids that possess longer half-lives as a result of the longer esters (Enanthate and Undecylenate). Trenbolone itself does not convert to Estrogen at any dose and is the strongest commercially available anabolic steroid known to man. It is also an anabolic steroid that is to be utilized by experienced anabolic steroid users only, and it is because of this that it fits very well with advanced users. Such a cycle should provide minimal Estrogenic activity and would be very suitable for cutting, lean mass addition, and even bulking cycles.
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.
