Sustaplex 325 is a perfect blend of five Testosterone compounds. The five different Testosterone esters provide for different half lives. Esterization of the Testosterone molecules provides for a sustained (but non-linear) release of Testosterone from the injection depot into the blood plasma.
While the intention of the mixed Testosterone esters in Sustaplex 325 is to provide more stable serum Testosterone levels, the long-ester Testosterones, such as Testosterone Cypionate (TestaPlex C 200) or Testosterone Decanoate, provide more stable serum Testosterone levels. Sustaplex 325 is the most popular testosterone blend product among those that use anabolic steroids for muscle building purposes.
As with all testosterone products, SustaPlex is a strong anabolic with pronounced androgenic activity. It is mainly used as a bulking drug, providing good gains in strength and muscle mass. Although it does convert to estrogen, as is the nature of testosterone, this injectable is noted as being slightly more tolerable than cypionate or enanthate. Such observations are only issues of timing however. With SustaPlex, blood levels of testosterone are building more slowly, so side effects do not set in as fast. For equal blood hormone levels however, testosterone will break down equally without regard to ester. Also correlating with estrogen, water retention would be noticeable with SustaPlex, unless steps were taken to minimize estrogen.
Although SustaPlex remains active in the body for approximately three weeks, injections are taken at least every 10 days. An effective dosage ranges from 250mg (one ampule) a week, to 1000mg (four ampules) weekly. Some athletes do use more extreme dosages of this steroid, but this is really not a recommended practice. When the dosage rises above 750-1000mg per week, increased side effects will no doubt be outweighing additional benefits. Basically you will receive a poor return on your investment, which with SustaPlex can be substantial. Instead of taking unnecessarily large amounts, athletes interested in rapid size and strength will usually opt to addition another compound. For this purpose we find that SustaPlex stacks extremely well with the potent orals Anadrol and Dianabol. On the other hand, SustaPlex may work better with trenbolone or Winstrol if the athlete were seeking to maintain a harder, more defined look to his physique.
