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.
Lets assume all who read this are going to supplement with Trenbolone responsibly and if you do the odds of a positive experience are far more in your favor. However, because it is impossible to predict if you have never supplemented with this hormone before you are highly advised to stick only with the Acetate version, often referred to as Tren-a. Trenbolone-Acetate is by many the preferred Trenbolone hormone but for the first time user it is the only logical choice The reason is simple; if you fall prey to the sever side effects of Tren you can simply discontinue use and have the hormone cleared from your system in a little more than 48 hours. If you choose a larger ester based form such as Trenbolone- Enanthate and fall prey to sever Tren side effects its a different story; it will take weeks for the hormone to clear after discontinuation.
