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.
Every batch is produced to a pharmaceutical-grade standard, verified by in-house and independent third-party testing, and shipped with a batch-specific certificate of analysis — backed by a 100% satisfaction guarantee. Here's exactly what that means, in plain English.
