Sustanon contains a hormone which is similar to the hormone testosterone that is produced by the body. Testosterone is a male sex hormone that is responsible for the development of male characteristics. These include growth of hair on the face and body, deepening of the voice, muscle development and the development of the male genitalia. Testosterone is also important for maintaining the strength of bones, libido and fertility in men. Men who do not produce enough testosterone may be prone to problems such as decreased libido, infertility or osteoporosis. In men who do not produce enough testosterone, Sustabol 350 is used to reduce the effects of a low level of testosterone.
 
People who have a female-to-male gender reassignment procedure may need to take Sustabol 350 to help strengthen male characteristics.
 
Sustabol 350mg contains testosterone decanoate/testosterone isocaproate/testosterone phenylpropionate/testosterone propionate.
