When demand for GLP-1s and GIP/GLP-1s leaped past what the manufacturers could provide, compounded versions popped up in online pharmacies and brick-and-mortar stores, for the following drugs: Ozempic (semaglutide) Rybelsus (semaglutide) Wegovy (semaglutide) Zepbound (tirzepatide) Mounjaro (tirzepatide) Retatrutide (This drug is not FDA approved.) However, the FDA cautions that compounded drugs, while useful or even necessary in some situations, are not FDA-reviewed or approved, so the FDA cannot guarantee their safety, quality, or effectiveness
Most guidance suggests using reconstituted tirzepatide within 28 to 30 days when stored at 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius)
Lyophilized (unmixed) powder is more stable: refrigerate for short-term use within 3-6 months
I just finished my first month of Tirzepatide (Mounjaro)
For example, if you always want to draw 50 units (0.50 mL) per dose for consistency: At 2.5 mg dose: Reconstitute for 5 mg/mL (2.5 divided by 5 = 0.50 mL) At 5 mg dose: Reconstitute for 10 mg/mL (5 divided by 10 = 0.50 mL) At 7.5 mg dose: Reconstitute for 15 mg/mL (7.5 divided by 15 = 0.50 mL) This "consistent draw" approach reduces the chance of dosing errors when transitioning between dose levels because you always draw the same volume
