Although Cypionate stays in the system for much longer than a week this product gets injected on a weekly basis. Some athletes even prefer to take this substance twice a week. It is not unheard of for an athlete to take up to 1000mg of this product per week. Cypionate is one of the most powerful mass building drugs available. Large doses are not necessary but many guys have reported taking huge amounts of this drug per week. Cypionate is stacked well with Equipoise, Deca, Dianabol or Anapolon. This product would generally not be used pre-contest due to the excessive water retention and the long duration in the blood. Once taking this substance you can not manipulate it the same way you can do with Propionate and you are bound to look smooth if attempting to use it pre contest.
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.
