PRODUCT OVERVIEW

SUSTANON 250 is an oil-based intramuscular testosterone preparation containing four testosterone esters with varying release profiles. This combination is designed to provide sustained testosterone delivery following administration and is used as testosterone replacement therapy in appropriately diagnosed patients.

INDICATIONS

SUSTANON 250 is indicated for testosterone replacement in males with confirmed testosterone deficiency or hypogonadism, based on clinical symptoms and laboratory testing.

It may be prescribed in cases involving:

• Primary hypogonadism
• Secondary hypogonadism
• Testosterone deficiency requiring androgen replacement therapy

DOSAGE & ADMINISTRATION

Administer by deep intramuscular injection only.

Dosage should be individualized based on:

• Patient condition
• Clinical response
• Serum testosterone monitoring
• Prescriber judgment

A commonly referenced regimen for testosterone ester combinations is 1 mL every 3 weeks, though dosing may vary depending on the patient’s therapeutic needs.

MECHANISM OF ACTION

SUSTANON 250 contains four testosterone esters that are gradually hydrolyzed in the body to release active testosterone.

This helps:

• Restore testosterone levels in deficient patients
• Support development and maintenance of male secondary sexual characteristics
• Promote androgen-dependent physiologic functions
• Provide both earlier and extended release due to mixed ester composition

PRECAUTIONS

Use with caution in patients with:

• Prostate disorders
• Breast carcinoma in males
• Hypertension
• Cardiac, renal, or hepatic impairment
• Diabetes mellitus

Important precautions:

• Monitor testosterone levels regularly
• Assess hemoglobin and hematocrit for polycythemia risk
• Monitor PSA and prostate health where appropriate
• Use caution with anticoagulants, corticosteroids, and antidiabetic therapy
• Avoid use in patients with known hypersensitivity to any component of the formulation
