The brand name Sustanon 250 refers to a particular class of injectable testosterone medicine. It is typically utilized in hormone replacement therapy (HRT) for males with low testosterone levels, while its anabolic properties are occasionally noted in bodybuilding circles. Each milliliter of the solution contains 250 mg of testosterone, hence the “250” in the name.

A naturally occurring hormone called testosterone is created by male testicles and, to a lesser extent, by female ovaries and adrenal glands. It is essential for the growth and upkeep of male sexual traits, as well as the preservation of bone density, muscle mass, and general levels of energy.
