Primobolan is an almost pure anabolic with a very low androgenic component. With this in mind, Primobolan is not suited for a rapid build-up of strength and mass, but is used over longer periods of time and leads to a quality muscle gain that remains pretty much intact after use. The compound is particularly well suited for use by women. It also combines very well with other steroids like Trenbolone, Winstrol, Oxandrolone and Equipoise. Primobolan is mostly use in the diet phase as it causes no water retention nor does it aromatize. It has also been noted that Primobolan has a positive effect on fat burning.
The Oxandrolone hormone does not carry any estrogenic related side effects. It does not aromatize and cannot lead to gynecomastia or water retention due to increases in estrogen levels. It further carries no progestin related activity, which again supports no estrogenic related side effects. Due to water retention being impossible with this steroid, this will decrease the risk of high blood pressure. Excess water retention can promote high blood pressure. Some steroids that do not aromatize can lead to high blood pressure, such as Trenbolone , but Anavar is rarely associated with this trait.
