The questions patients actually ask.

Short, honest answers. The long version happens with your clinician, using your labs.

Which is more effective?

In head to head research, tirzepatide produced greater average weight loss. But averages hide individuals: plenty of people respond better to semaglutide, tolerate it better, or reach their goal on either. Your response is discovered, not predicted.

Which costs less?

Your AlyneMD program fee is identical for both. Medication cost depends on your pharmacy benefits and manufacturer savings programs, which our coverage check estimates before you commit to anything.

Can I switch between them?

Yes, and patients do, in both directions, guided by response and tolerability. Switching is a clinical decision your clinician manages, not a new enrollment.

What about oral options?

Oral GLP-1 medication is the newest entrant and availability is expanding now. If needles are the obstacle, raise it at your visit.
