Sistanon Injection is a clear pale yellow solution having the active ingredient testosterone, which is a natural male hormone. Testosterone is produced by the testicles for normal growth and function of the male sex organs as well as male sex characteristics. This is also necessary for the growth of body hair and development of bones. This medicine is widely used in adult men for replacing testosterone for treating various health problems caused due to lack of testosterone. It is also used as supportive therapy to treat female-to-male transsexuals. In addition to this, it is available in high-quality packaging materials to keep the properties intact.
