Sustanon is a very popular steroid due to the fact that it offers several advantages when compared to other testosterone compounds. Sustanon is a mixture of four different testosterones which have a synergetic effect. This special feature has two positive characteristics for the athlete. First, based on the special combination effect of the compounds, Sustanon, per milligram, has a better effect than Testosterone enanthate, cypionate, and propionate alone. Next, the effect of the four testosterones is time released so that Sustanon goes rapidly into the system and remains effective in the body for several weeks. Due to the propionate also included in the steroid, Sustanon is effective after one day and, based on the mixed in decanoates, remains active for 3-4 weeks. Sustanon has a distinct androgenic effect which is coupled with a strong anabolic effect. It is well suited to build up strength and mass. A rapid increase in body strength and body weight occur. Athletes who use Sustanon report a solid muscle growth since it results in less water retention and also aromatizes less than either testosterone enanthate or cypionate.
