Searches for "gip 1 agonist" almost always mean tirzepatide (tirzepatide, marketed under brand names Mounjaro (type 2 diabetes) and Zepbound (chronic weight management); also available through licensed compounding pharmacy pathways). This is a brief disambiguation post that explains what tirzepatide is, what it's FDA-approved for, and where to go from here.
What tirzepatide actually is
Tirzepatide is a GIP and GLP-1 dual receptor agonist marketed under brand names Mounjaro (type 2 diabetes) and Zepbound (chronic weight management); also available through licensed compounding pharmacy pathways. It is FDA-approved for type 2 diabetes (Mounjaro, 2022). Tirzepatide is administered as a once-weekly subcutaneous injection (FDA-approved formulation) per its FDA label. Per-month list price as of April 2026 is approximately $1,059–$1,069 per month at U.S. list price as of April 2026 (Eli Lilly published pricing for Zepbound and Mounjaro).

Where this leaves you
If you were searching for tirzepatide: it is a real, FDA-approved GIP and GLP-1 dual receptor agonist available by prescription. The PlexusDx Weight Management Protocols collection includes the active ingredient (tirzepatide) through clinician-supervised compounded protocols. To start upstream with the genetic context, the Precision Peptide Genetic Test analyzes the GLP-1 pathway biology that sits underneath any of these decisions.
Upstream of any GLP-1 protocol decision, the PlexusDx Precision Peptide Genetic Test analyzes 14 pathways, 49 peptides, and 150+ genetic insights — including variants in FTO, GLP1R, and MC4R that shape baseline GLP-1, appetite-regulation, and energy-balance biology. That genetic context is the test before you invest framing PlexusDx applies to every protocol conversation.

Disclaimer: This article is educational. PlexusDx offers tirzepatide through its Weight Management Protocols — this article covers the mechanism, evidence, and genetic context that informs any decision to use it. The Precision Peptide Genetic Test analyzes how your genes influence peptide-related biological pathways — it does not predict response to any specific medication. Consult a qualified healthcare provider before beginning any peptide protocol.

Frequently Asked Questions
Is "gip 1 agonist" the same as tirzepatide?
Yes — "gip 1 agonist" is a common misspelling or phonetic search variant of tirzepatide (tirzepatide, marketed under brand names Mounjaro (type 2 diabetes) and Zepbound (chronic weight management); also available through licensed compounding pharmacy pathways). It is the same medication. Tirzepatide is FDA-approved for type 2 diabetes (Mounjaro, 2022) and is administered as a once-weekly subcutaneous injection (FDA-approved formulation).
How is tirzepatide actually spelled?
Tirzepatide is the brand name; the active ingredient is tirzepatide, marketed under brand names Mounjaro (type 2 diabetes) and Zepbound (chronic weight management); also available through licensed compounding pharmacy pathways. Confusion with the spelling is common because the name is unusual. The FDA label and manufacturer materials use the spelling "tirzepatide".
Where can I learn more about tirzepatide?
The Mounjaro/Zepbound product website and the FDA label are the primary sources. The PlexusDx Education Hub also has explainer content on the GLP-1 receptor agonist class — including the tirzepatide active ingredient and the genetic pathways that underlie all GLP-1 protocol decisions.
