What the research says

Tirzepatide acts on two receptors — GLP-1 and GIP — which is why the research community describes it as a 'dual agonist.' The addition of GIP signaling is the key distinction from semaglutide.

Its clinical trial program produced striking body-composition and glucose-regulation results, and it remains one of the most-searched metabolic research compounds. As with semaglutide, the research-market product is for laboratory use only and separate from the approved prescription medicine.

The COA and legal framing conversation is identical to the rest of the GLP-1 class — and arguably more important given how much counterfeit product this category attracts.

For research use only. Tirzepatide is referenced here strictly for laboratory and research purposes — not for human consumption, and not as medical advice, diagnosis, or treatment. Nothing on this page claims any effect in humans.
