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.
