In SURMOUNT-1, Zepbound (brand tirzepatide) produced about 22.5% average body-weight loss over 72 weeks. Compounded versions were not in that trial, and the FDA does not review compounded drugs for potency, purity, or effectiveness — do not expect the same result. That is a trial average; individual results vary widely and depend on staying on treatment.
What Compounded Tirzepatide is approved for
