A plain-English breakdown of the three medications every patient in Tupelo is asking about, and how a clinic decides which one to start.

Three medications, three mechanisms
Semaglutide works on a single receptor pathway. Tirzepatide works on two. Retatrutide, the newest of the three, targets three. More receptor coverage generally means stronger appetite suppression and faster early results — and also means candidacy screening matters more, not less.
The right answer is rarely the newest option. It is the option a patient can tolerate, afford, and stay on long enough for the habits to hold.
How a provider actually chooses
Starting therapy comes down to four inputs: prior medication history, tolerance for nausea, budget, and how much weight there is to lose. A patient with 25 pounds to lose and a sensitive stomach is a different plan than a patient with 120 pounds to lose and a history of insulin resistance.
Every plan should include a written titration schedule, a protein target, and a date for the first progress review.
What to ask before you start anywhere
Ask what the monthly cost is at every dose level, not just the starting dose. Ask who you call at 8pm with a side effect. Ask what the plan is at month nine, when the weight comes off and the question becomes maintenance.
