How They Differ

Semaglutide copies one gut hormone (GLP-1). Tirzepatide copies two (GLP-1 and GIP), which seems to add appetite control and metabolic benefit. Both are weekly injections with the same dose-step approach.

Results

In the direct comparison trial, tirzepatide led to about 20 percent weight loss at 72 weeks versus about 14 percent for semaglutide. Semaglutide has published data showing fewer heart attacks and strokes in people with heart disease.

Side Effects

Similar lists: nausea, constipation, fatigue. Tirzepatide is often reported as a bit gentler on nausea at equivalent loss.

Cost

Brand: both around $1,000 a month or more without coverage. Compounded at Zen IV Spa: semaglutide $199, tirzepatide $299. Most people start on semaglutide and move to tirzepatide if they plateau or want more.

Choosing

More to lose, or diabetes in the family: tirzepatide. Budget, or heart disease history: semaglutide. Either way, labs at home and a provider who adjusts. Every prescription at Zen IV Spa is written by a licensed provider under our medical director after a free video consultation.
