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.
In one small scale clinical trial of depressed patients, an improvement of symptoms which included anxiety, lack of drive and desire was observed.  In patients with dysthymia , unipolar , and bipolar depression significant improvement was observed.  In this series of studies, mesterolone lead to a significant decrease in luteinizing hormone and testosterone levels.  In another study, 100 mg mesterolone cipionate was administered twice monthly.  With regards to plasma testosterone levels, there was no difference between the treated versus untreated group, and baseline luteinizing hormone levels were minimally affected. 
The Mesterolone hormone is not estrogenic. It does not aromatize and it carries no progestin nature. As a result, the side effects of Proviron will not include any related effects such as gynecomastia or excess water retention. Such adverse effects are impossible with this steroid. This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use is often due to extreme water retention. In fact, Proviron should provide an anti-estrogenic effect by preventing testosterone to estrogen conversion or at least tremendously slow it down.
