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.
The average Trenbolone Acetate dose varies based on your cycle and stack. During an off-season bulking cycle, most bodybuilders find that 50mg every other day is comfortable and effective. Some men tolerate up to 100mg every other day with no issues, and they find that this does offers the best results for them. During a cutting cycle, people tend to push the envelope a little more with Tren and utilize doses even higher than 100mg every other day, but not everyone can tolerate these as the risk of side effects increases. No one should ever use more than 200mg every other day, even if they seem to tolerate it well.
