Tirzepatide is a dual incretin receptor agonist, meaning it activates two key hormone pathways: GLP-1 and GIP. These hormones play essential roles in appetite regulation, digestion, insulin release, and metabolic balance.

Compounded tirzepatide is prescribed when clinically appropriate and prepared by licensed compounding pharmacies. It is used alongside lifestyle changes such as improved nutrition and physical activity.

Tirzepatide works by stimulating both GLP-1 and GIP receptors, creating a combined effect on metabolic regulation.

It helps:

• Reduce appetite and cravings

• Slow gastric emptying to extend feelings of fullness

• Improve insulin sensitivity

• Reduce post-meal glucose spikes

These mechanisms support steady metabolic improvements when paired with dietary and lifestyle changes.

Tirzepatide is the active ingredient in both Mounjaro® and Zepbound®. These FDA-approved medications are brand-name versions with specific approved uses, dosing systems, and patient guidance.

Compounded tirzepatide:

• Is not the same as commercially manufactured products

• Is not FDA-approved

• Is prepared by compounding pharmacies

Your GGRx provider will explain the differences and determine the most appropriate option.

Most people begin noticing appetite-related effects—such as reduced cravings or feeling full sooner—within the first few weeks, especially as their dose slowly increases.

More comprehensive metabolic changes often occur over several weeks to several months, depending on dose schedule, consistency, and individual physiology.

Tirzepatide may be considered for adults with obesity, or overweight with a weight-related health condition, based on the clinical judgement of a licensed provider.

Strong candidates often include individuals with:

• Difficulty regulating hunger

• Metabolic challenges such as insulin resistance

• A desire for structured long-term support

Eligibility is always determined through a medical consultation.

Common side effects mainly involve the digestive system and often occur during dose escalation. These may include:

• Nausea

• Vomiting

• Diarrhea

• Constipation

• Abdominal discomfort

These are typically temporary and may improve as the body adjusts. Your provider may adjust your dosing schedule if needed.

No. Tirzepatide should not be combined with:

• GLP-1 agonists

• Other tirzepatide medications

• Weight-loss injectables targeting similar pathways

Combining similar medications increases the risk of side effects and is not medically recommended.

No. Compounded tirzepatide is not FDA-approved.
However, compounding is permitted under federal and state laws when medications are prepared by licensed pharmacies for patients with specific clinical needs.

FDA-approved tirzepatide medications do exist, and your provider may discuss whether a compounded or FDA-approved option is appropriate.

Insurance coverage typically applies only to FDA-approved tirzepatide products and usually for type 2 diabetes or chronic weight management under strict criteria.

Because compounded tirzepatide is not FDA-approved, insurance generally does not cover it.
