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.
There are two of interests that fill the category of the most powerful muscle building steroids of all but the king of kings is that of Trenbolone . Because of Testosterone’s efficiency it is a close second, a very close second but Trenbolone is 400 times more powerful than testosterone; that’s not an arbitrary number, it is literally 400 times more potent and powerful. Not only are the various Trenbolones the most powerful muscle building steroids of all, they are the most potent steroids to serve any cycle for any purpose.
