Compounded Tirzepatide vs Compounded Semaglutide: How To Choose
Compounded GLP-1 telehealth in 2026 isn't one product — it's two. Semaglutide (the active in Wegovy and Ozempic) and tirzepatide (the active in Zepbound and Mounjaro) are different molecules with different receptor activity, different efficacy ceilings, and different side-effect profiles. Most provider pages let you pick one without explaining the trade-offs. Here's the framework.
The Pharmacology Difference
Semaglutide is a single-receptor GLP-1 agonist. Tirzepatide is a dual GIP and GLP-1 agonist — it activates both the GLP-1 receptor that semaglutide hits and the GIP (glucose-dependent insulinotropic polypeptide) receptor that semaglutide doesn't. The dual mechanism appears to translate to greater weight loss in head-to-head data: SURMOUNT-1 (tirzepatide 15 mg) showed mean 20.9% weight loss at 72 weeks versus STEP 1 (semaglutide 2.4 mg) at 14.9% over 68 weeks.
Side-Effect Profile: Similar, But Not Identical
Both molecules cause GI side effects — nausea, diarrhea, vomiting, constipation — in the first few months of titration. In trial data, the rates are broadly comparable, with some signal that tirzepatide produces slightly more nausea and slightly less constipation. The clinical experience: most patients tolerate either one if titrated slowly; the patients who can't tolerate semaglutide sometimes do better on tirzepatide and vice versa, which is one reason flexibility between the two matters when picking a clinic.
Pricing in 2026
| Compounded semaglutide | Compounded tirzepatide | |
|---|---|---|
| Typical monthly cost | $199–349 | $329–499 |
| Lowest entry program | ~$179/mo | ~$299/mo |
| Concierge tier | ~$449/mo | ~$549/mo |
| Typical maintenance dose | 1.7–2.4 mg/wk | 10–15 mg/wk |
Tirzepatide consistently runs 30–60% more expensive than semaglutide at compounded pricing. The cost difference reflects bulk active-ingredient pricing and the relative novelty of tirzepatide compounding (semaglutide has been compounded at scale for longer).
Who Should Pick Which
- Pick semaglutide if: you're cost-sensitive, you've tolerated it before, or you have a longer titration runway and don't need the higher efficacy ceiling.
- Pick tirzepatide if: you have a higher BMI and want maximum efficacy, you've plateaued on semaglutide, or your insurance pathway to brand Zepbound is blocked.
- Pick a clinic that offers both: you may want the option to switch later, and clinics that only carry one molecule lock you in.
