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.
Methandienone (also known as methandrostenolone, Dbol, dianabol) is an orally-effective anabolic steroid originally developed in Germany and released in the US in the early 1960s by Ciba Specialty Chemicals. This is a derivative from testosterone, one of the most popular steroid compounds in the world and the second steroid (after testosterone) ever produced. Methandienone promotes dramatic increases in protein synthesis, glycogenolysis, and muscle strength over a short space of time.
