Saizen is a synthetic version of the human growth hormone (hGH), prescribed for the treatment of growth hormone deficiency and certain conditions leading to short stature and growth failure. Manufactured through recombinant DNA technology, Saizen mimics the natural growth hormone produced by the pituitary gland, facilitating normal growth and development in children and adults lacking sufficient natural growth hormone.

Before you buy Saizen, it is crucial that you talk to your healthcare provider about potential side effects and Saizen cost.

Directions

Begin with a consultation with your healthcare provider to ensure Saizen is appropriate for your condition.

Saizen must be prescribed by a healthcare professional.

Follow the specific instructions for reconstitution and administration provided by your healthcare provider. Saizen is typically administered via subcutaneous injection. The Saizen dosage and frequency of administration will be determined based on individual requirements, including age, weight, and the condition being treated.

Regular follow-ups with your healthcare provider are necessary to monitor growth progress, adjust dosages as needed, and check for side effects.
