Important safety information. This tool and page provide general information, not medical advice, and their estimates are not a diagnosis or a treatment recommendation. Talk with a licensed clinician before starting, stopping, or changing any treatment. Eligibility for treatment is determined individually by a licensed provider through the online assessment.
Compounded medications are prepared per individual prescription by a state-licensed 503A sterile compounding pharmacy and are not FDA-approved as drugs. The active ingredients (semaglutide, tirzepatide) are FDA-approved in commercial formulations such as Wegovy, Ozempic, Mounjaro, and Zepbound; compounded preparations are not those products.
GLP-1 medications carry risks including nausea, vomiting, diarrhea, constipation, pancreatitis, gallbladder disease, acute kidney injury, and a boxed warning for the risk of thyroid C-cell tumors. They are contraindicated in patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2. Tell your provider about your full medical history and current medications. Individual results vary; any figures shown are clinical-trial averages or estimates, not guarantees.
