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.
According to the aggregate data from a number of scientific studies, despite its conservative nature, Primobolan was proven to provide significant increases in muscle development in a reasonable amount of time. Another interesting fact that was discovered during the testing of this compound was the fact that it effectively bound itself to the AR. In fact, Primobolan was able to bind itself to the AR more effectively than naturally produced testosterone. This is huge because the ability to effectively bind to the AR allows Primobolan to be one of the most effective fat-burning compounds available. Positive AR binding has been directly correlated with lipolysis.
