Head to head

Cagrilintide vs Tirzepatide

MetabolicGLP-1 / incretin

A comparison decided mostly by evidence: Tirzepatide has been studied in people to a degree the other has not.

Verdict

Tirzepatide rests on firmer evidence

If your priority is the compound with the strongest published support, that is Tirzepatide. Cagrilintide is not therefore worse — it is less examined, which is a different thing — but the gap is the single most defensible difference on this page, and it is the one most comparisons quietly skip.

What you are actually choosing between

These sit in different classes. Cagrilintide is a metabolic compound; Tirzepatide is a GLP-1 / incretin agonist. They get compared because of where they overlap, not because they are interchangeable.

The overlap is appetite control, fat loss, and metabolic health. On this site's goal weighting — an editorial priority score, not a measure of effect size — Cagrilintide rates 5/5 for appetite control and Tirzepatide rates 5/5.

The evidence

This is the part that decides most of it. Tirzepatide has an approved label and the randomized trial package behind it — head-to-head trials put its average weight loss above semaglutide. Cagrilintide has controlled human trials behind it, without an approval — investigational; standalone long-term data does not exist yet. That gap is the headline, and it is a statement about the literature rather than a promise about you: a compound with trial data can still do nothing for your case, and one without it is unproven rather than disproven.

How they differ in practice

Half-lives are close — 7.5 days for Cagrilintide, 5 days for Tirzepatide — and both are dosed once a week, so the rhythm of actually running them is the same.

Risk and difficulty

The contraindication lists are not the same: Cagrilintide flags under 18, which Tirzepatide does not; Tirzepatide flags MTC or MEN2 history, pancreatitis history, and thyroid disease, which Cagrilintide does not. If any of those describe you they remove a compound from consideration outright, regardless of everything above.

Tirzepatide is rated intermediate here and Cagrilintide advanced. That rating is about how much can go wrong in handling, dosing and monitoring, not about how well either works.

Source notes

What the evidence actually says

Verbatim, so you can check the verdict above against what it was built from.

Cagrilintide

Long-acting amylin analogue, not a GLP-1. Phase 2 randomized human trials dosed 0.3 to 4.5 mg once weekly with 4-week step-ups, and it is in phase 3 combined with semaglutide as CagriSema. It is investigational and NOT approved anywhere as a standalone product. Amylin analogues act on satiety through a different receptor to GLP-1, which is the rationale for the combination, but standalone long-term data does not yet exist.

Tirzepatide

Dual GIP/GLP-1 receptor agonist. Head-to-head trials show larger average weight loss than semaglutide. FDA approved under brand names.

They overlap on 3 goals and diverge on 0. Weights are this site’s editorial priority score out of 5 — how central a goal is to why people use a compound. They are not effect sizes and two 5s do not mean two equal results.
