Sustanon 250 Injection is an androgen replacement therapy used to treat testosterone deficiency (male hypogonadism) in adult men. It is a combination medicine containing four esters of testosterone (propionate 30mg, phenylpropionate 60mg, isocaproate 60mg and decanoate 100mg per ml), and belongs to a class of medicines called androgens.
This medicine works by releasing testosterone gradually into the body as the esters are broken down, with the shorter-acting esters acting first and the longer-acting decanoate keeping levels steady. This helps restore testosterone levels and ease symptoms such as low sex drive, tiredness and loss of muscle mass. It is given as a slow, deep injection into a muscle by a doctor or nurse, at the interval decided by your doctor.
Your doctor may advise regular blood tests and check-ups during treatment. This medicine is not for use in children or adolescents.
Before starting this treatment, tell your doctor if you have prostate or breast cancer, heart, liver or kidney problems, or an allergy to peanuts or soya, as the injection contains arachis (peanut) oil. Tell your doctor about any other medicines you take. Contact your doctor if you have a sudden cough, breathlessness or dizziness during or just after an injection.
