1 vial of 1 ml contains 250 mg (30mg testosterone propionate,60mg tetsosterone phenylpropionate,60mg testosterone isocaproate,100mg testosterone decanoate).Sustanon is a very popular steroid which is highly appreciated by its users since it offers several advantages when compared to other testosterone compounds. Sustanon is a mixture of four different estosterones which, based on the well-timed composition, 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, milligram for milligram, has a better effect than Testosterone enanthate, cypionate, and propionate alone. Second, 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. Therefore it is well suited to build up strength and mass. A rapid increase in body strength and an even increase in 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. Indeed many bodybuilders who use testosterone and fight against distinct water retention and an elevated estrogen level prefer Sustanon over other long-acting depot testosterones.
