Sustanon is a medication available in 1ml ampoules, with each ampoule containing 250mg/ml of the active ingredients. It is an injectable testosterone preparation commonly used in hormone replacement therapy (HRT) for individuals with low testosterone levels. Sustanon contains a blend of four different testosterone esters, including testosterone propionate, testosterone phenylpropionate, testosterone isocaproate, and testosterone decanoate. These esters are designed to provide a sustained release of testosterone into the body, ensuring stable hormone levels over an extended period of time. Sustanon is typically administered by a healthcare professional and may be prescribed for various conditions related to testosterone deficiency. It is important to follow the prescribed dosage and administration instructions provided by your healthcare provider.
