Sustanon

Sustanon general information

Sustanon 250 is a trade name for an oil-based injectable blend of four esterized testosterone compounds:

• 30mg Testosterone
• 60mg Testosterone
• 60mg Testosterone
• 100mg Testosterone

The different testosterone esters provide for different half lives. Esterization of the testosterone molecules provides for a sustained (but non-linear) release of testosterone from the injection depot into the blood plasma.

While the intention of the mixed testosterone esters in Sustanon is to provide more stable serum testosterone levels, a single long-ester testosterone, such as testosterone cypionate or testosterone enanthate, may actually provide more stable serum testosterone levels. It is the preferred method of testosterone replacement in the UK as detailed in the British National Formulary.

Sustanon dosage and dministration

Testosterone is given as replacement therapy when natural testosterone levels fall too low, causing symptoms such as those above. Natural testosterone levels fall with age and following surgical removal of the testicles (castration). They may also fall due to decreased functioning of the testicles (hypogonadism or eunuchoidism) caused by testicular disease, or by decreased gonadotrophin production by the pituitary gland, as a result of pituitary disease.

Testosterone replacement allows natural testosterone levels to return to normal, thus relieving the symptoms of the deficiency.

Sustanon injection is called a depot injection. It is injected slowly into the muscle where it forms a reservoir of medicine. The testosterone is gradually released all the time from the reservoir into the bloodstream. The injection is usually given once every two to three weeks, though the frequency will depend on your individual testosterone levels.
