    Frequently Asked Questions

    How do I choose between semaglutide and tirzepatide?

    Consider your budget ($125/mo vs $125/mo), weight loss goals (moderate vs aggressive), and health conditions. Tirzepatide may be better for insulin resistance, PCOS, and higher weight loss targets. Semaglutide has a longer safety track record and is more affordable.

    Who should consider retatrutide?

    Retatrutide may be ideal for patients who have plateaued on semaglutide or tirzepatide, those with very high BMI (40+), patients with fatty liver disease, or those seeking maximum possible weight loss. It works on three receptors instead of one or two.

    Can I switch medications if one doesn't work?

    Yes. Switching between GLP-1 medications is common and safe. If semaglutide produces insufficient results, upgrading to tirzepatide often restarts weight loss. Your Trimi provider can guide the transition protocol.

    Should I start with the cheapest option first?

    Starting with semaglutide ($99/mo) is a reasonable approach for many patients. If results are satisfactory, there's no need to switch. If you need more aggressive weight loss, you can upgrade to tirzepatide ($125/mo) at any time.
