TIRZ — Tirzepatide (Lyophilized Research Peptide, 5mg–120mg)
TIRZ (Tirzepatide) is a dual GIP and GLP-1 receptor agonist peptide studied in metabolic and endocrinology research models. It is widely explored for its combined action on glucose-dependent insulin secretion and appetite-related signaling pathways.
Due to its dual-receptor activity, Tirzepatide is commonly investigated in research focused on metabolic efficiency, glucose control mechanisms, and energy balance regulation. For background on how these receptor pathways are studied, see our tirzepatide research guide and our overview of GLP-1 research peptides.

How Tirzepatide Compares to Other GLP-1 Research Peptides
Tirzepatide is a dual agonist acting on the GIP and GLP-1 receptors — one more pathway than semaglutide (GLP-1 only) and one fewer than retatrutide (GLP-1/GIP/glucagon). For a side-by-side of dose ranges and trial outcomes, see semaglutide vs tirzepatide.
| Compound | Receptor Targets | Research Class |
|---|---|---|
| Tirzepatide (TIRZ) | GLP-1 + GIP | Dual agonist |
| Semaglutide (SEMA) | GLP-1 | Single agonist |
| Retatrutide (RETA) | GLP-1 + GIP + Glucagon | Triple agonist |
Selected Research Literature
Tirzepatide is among the most heavily published dual-incretin agonists in metabolic research. Representative peer-reviewed reading:
- Jastreboff AM, et al. — SURMOUNT-1: tirzepatide once weekly in adults with obesity. [PubMed]

Tirzepatide (TIRZ) — Frequently Asked Questions
Where can I buy tirzepatide research peptide?
You can buy the tirzepatide research peptide directly from MyGLP1Store in vial sizes from 5mg to 120mg. Every batch is third-party tested and ships same-day from the US. For laboratory research use only.
What is TIRZ?
TIRZ is the abbreviation for Tirzepatide, a dual GIP and GLP-1 receptor agonist peptide studied in metabolic and endocrinology research. MyGLP1Store supplies TIRZ as a lyophilized research peptide for laboratory use only.
Is TIRZ the same as Tirzepatide?
Yes. TIRZ is simply the short form of Tirzepatide used by researchers — it is the same dual-agonist research peptide.
Is TIRZ third-party tested?
Yes — every batch is third-party lab tested for purity and identity before release, at documented >99% purity.
What other GLP-1 research peptides does MyGLP1Store offer?
Researchers studying TIRZ often also work with Cagrilintide (CAGRI), Semaglutide (SEMA), Retatrutide (RETA), and other compounds in our obesity research collection.

Although I have not tried my peptide yet, I am excited. Everything arrived promptly. Unlike other peptide companies I was pleasantly surprised, they sent syringes and biostatic water for reconstituting. I also love as a company they donate a portion of my purchase price to animal organizations. Looking forward to purchasing from them again.
