GLP-1 & GIP/GLP-1 Receptor Agonists

Incretin mimetics prescribed for type 2 diabetes and chronic weight management — including semaglutide and the dual GIP/GLP-1 agonist tirzepatide.

About GLP-1 Agonists

GLP-1 receptor agonists mimic the gut hormone glucagon-like peptide-1, improving glycemic control and reducing appetite. Tirzepatide additionally activates the GIP receptor. Compounding of these medications is tightly restricted under FDA 503A rules: a licensed prescriber must document a clinical reason (e.g., allergy to an inactive ingredient, non-commercial dose) that the FDA-approved product is not appropriate for the patient. Cost is not a valid clinical justification. Compounded formulations may include combination therapies (semaglutide with B12, L-carnitine, or NAD+) when specifically prescribed.
