Details
This product requires a doctor's consultation.
Tirzepatide is a once-weekly injectable medication that acts as a dual GIP and GLP-1 receptor agonist. It regulates insulin secretion, slows gastric emptying, and reduces appetite.

Frequently asked
What does the provider review involve?
After you order, The Protocol Network coordinates an intake form and async review with an independent licensed provider through OutfitMD. We don't make the medical decision — the provider does.
How quickly do orders ship?
Once your prescription is reviewed and approved by an independent licensed provider, the sourcing pharmacy ships within 2–5 business days. Tracking lands in your email.
How should I store my peptides?
503A compounded vials ship refrigerated and should stay refrigerated. 503B lyophilized powders are shelf-stable until reconstituted; refrigerate once mixed. Specifics are on each product's label.
