Sustanon is a very popular steroid which is highly appreciated by its users b/c Sustanon offers several advantages when compared to other testosteron compounds. Sustanon is a mixture of four different testosterones which, based on the well-timed composition, have a synergetic effect. Sustanon 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.

It is further noticed that Sustanon is also effective when relatively low doses are given to well advanced athletes. It is interesting to note that when Sustanon is given to athletes who have already used this compound in the same or lower doses, it leads to similar good results as during the previous intake. Sustanon is usually injected at least once a week., which can be stretched up to 10 days. The dosage in bodybuilding and powerlifting ranges from 250 mg every 14 days up to 1000 mg or more per day. Since such high dosages are not recommended and fortunately are also not taken in most cases the rule is 250-1000 mg/week. A dosage of 500 mg/week is completely sufficient for most, and can often be reduced to 250 mg/week by combining with an oral steroid. Sustanon is well tolerated as a basic steroid during treatment which stimulates the regeneration, gives the athlete a sufficient "kick" for intense training units, and next to the already mentioned advantage rapid strength increase and solid muscle gain distinguishes itself also by its compatibility. In order to gain mass fast Sustanon is often combined with Deca Durabolin, Dianabol (D-bol) or Anadrol while athletes who are more into quality prefer combining it with Winstrol, Anavar or Primobolan.

Although Sustanon does not aromatize excessively when taken in a reasonable dosage many people, in addition, also take an antiestrogen such as Nolvadex and/or Proviron to prevent possible estrogen-linked side effects. Since Sustanon suppresses the endogenous testosterone production the intake of HCG and Clomid must be considered after six weeks or at the end of treatment. It is recommended that women not take depot testosterones since the androgen level would strongly increase and virilizalion symptoms could result.

The side effects of Sustanon are similar to those of Testosterone enanthate only that they are usually less frequent and less severe. Depending on the predisposition and dosage, the user can experience the usual androgenic-liked side effects such as acne, aggressiveness, sexual overstimulation, oily skin, accelerated hair loss, and reduced production of the body's own hormones. Water retention and gynecomastia are usually within limits with the Sustanon; or are not as massive as with enanthate and cypionate. Liver damage is unlikely with Sustanon however, in very high dosages, elevated liver values can occur which, after discontinuing use of the compound, usually go back to normal.
