Yes, the brand name Sustanon 250 Australia refers to a particular class of anabolic steroid medicine that contains a combination of testosterone esters. A naturally occurring hormone in the body, testosterone is essential for many bodily processes, including the growth and development of muscles.

Sustanon may support greater muscle growth and strength when used under medical supervision, such as for hormone replacement treatment in those with low testosterone levels. In order to build muscles, testosterone is known to encourage muscle protein synthesis and nitrogen retention.
