Common questions
Simply Wurth It names Semaglutide and Tirzepatide on its own site. That is what the clinic advertises, not a guarantee of supply, and which medication you start on is decided at the evaluation.
Simply Wurth It sees patients at its St. Louis location and its site describes video visits as well. Ask which appointments have to happen in person, since the first evaluation often does.
Mercedes Devlin, FNP is named as a prescriber on the clinic's site, not yet matched to a licensing registry.
Simply Wurth It does not publish a program price. Ask for the total first-month cost and what it becomes after, and whether labs and follow-up visits sit inside that figure or outside it.

Worth comparing before booking, since what a program includes and what it charges after the first month differ more between clinics than the medication does.
