Sustanon is a mixture of 4 different testosterones which based on the well timed composition, have a synergetic effect. This special feature has positive characteristics for the athlete.The effect or the 4 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, remain 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.
