Sustanon is a four Testosterone esters combination. The four different substances work together in such a timely manner that Sustanon remains in the body for a long time.

In bodybuilding and powerlifting Sustanon is exclusively used to build up strength and mass. The pronounced androgenic component of Sustanon goes hand in hand with a high anabolic effect which manifests itself in a high strength gain characterized by a liquid accumulation in the joints, an increased pump effect, increased appetite, and a possible improved regeneration of the athlete. Since Sustanon easily aromatizes, the intake of antiestrogens is suggested. This can also help reduce some of the water retention. Although Sustanon has a duration effect of a good 2-3 weeks it is usually injected at least once a week.

As for the dosage there is rarely an injectable steroid with a wide spectrum such as Sustanon's. The span reaches from athletes who inject one 250 mg injection every two weeks to extremes who use eight(!) a day (2000 mg/day). An acceptable and, for most, sufficient dosage is 250 to 1000mg/week. Sustanon is often combined with Dianabol, Anadrol 50, and Deca Durabolin which accelerates the gain in strength, mass, and water retention. The gains achieved with Sustanon, as is the case with Testosterone, for the most part, usually subside up to 30% very quickly after use of the compound is discontinued.

The side effects of Sustanon are similar to those of other testosterone compounds. Next to the high water retention other negative effects that are noticed are a sometimes strong acne and a distinctly increased aggressiveness in some users. An aggressive behavior can mostly be explained by the fact that athletes simply use too high a dosage of Sustanon and too low a dosage of the other (and more expensive) testosterones. The very severe acne, however, is only caused by Sustanon. Often no purulent pustules but many small pimples appear so that the athlete looks as if he has an allergy. This is not intended to discourage anyone but it is a fact that many athletes after a brief time develop an acne on their lower arm, upper arm, shoulder, chest, back, and also in their face which, during an earlier intake of Sustanon or Testosterone enanthate, did not manifest itself. Women should not use Sustanon under any circumstances.
