Primobolan, although with a weaker effect than Deca Durabolin, is a good basic steroid with a predominantly anabolic effect and, depending on the goal, can be effectively combined with almost any steroids. Those who would like to gain mass rapidly and do not have Deca Durabolin available, can use Primobolan together with Sustanon and Dianabol (D-bol).  Primobolan is not converted into estrogen however, low water retention can occur.

Side effects with Primobolan are minimal and manifest themselves only rarely and in persons who are extremely sensitive. Due to the androgenic residual effect, side effects include light acne, deep voice or increased hair growth. Primobolan has small influence on the liver function so that an increase of the liver's toxin values is extremely unlikely. The blood pressure, cholesterol level, HDL and LDL values usually remain unaffected. Primobolan is generally the safest injectable steroid. Athletes whose liver values strongly increase when taking anabolic steroids but who still do not want to give up their use, under periodical supervision of these values, can go ahead and try a stack of Primobolan, Deca Durabolin and Andriol. Primobolan has only a very small influence on the testicular axis so that the body's own testosterone production is only reduced when very high dosages are taken over a prolonged period of time.

100 mg Primobolan Depot/week, combined with 50 mg Winstrol/week, is usually an effective stack for many women and is tolerated well so that virilization symptoms are rarely observed. To avoid an undesired accumulation of androgens in the body women should pay attention that there are three to four days in between the relative injections.
