SUSTANON 250® is an oil-based testosterone blend that contains four different testosterone esters. It is designed to provide a fast yet extended release of testosterone, providing exceptional gains in strength and muscle mass. Although Sustanon remains active in the body for approximately three weeks, injections are taken at least every 5 days to maintain stable serum concentration. As with all testosterone products, Sustanon is a strong anabolic with pronounced androgenic activity.
It is most commonly used as a bulking drug, providing exceptional 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. With Sustanon, blood levels of testosterone are building more slowly, so side effects do not set in as fast.
Sustanon stacks extremely well with Anadrol and Dianabol during bulking cycle. On the other hand, Sustanon may work better with trenbolone or Winstrol if the athlete were seeking to maintain a harder, more defined look to his physique.
