What Are GLP-1 Research Peptides?
GLP-1 research peptides are incretin-pathway compounds studied for how they engage the receptors that govern glucose homeostasis and energy balance — GLP-1, GIP, glucagon, and amylin receptors. This collection is organized by how many receptors each compound targets, from dual- through triple-agonist designs, supplied lyophilized at high purity for laboratory research use only.
Single, Dual, and Triple Receptor Agonists
Researchers choose a GLP-1 peptide by the receptor breadth their model requires. TZ-2 is a dual GLP-1/GIP agonist; RT3 is a triple GLP-1/GIP/glucagon agonist; and Cagrilinitide targets the amylin receptor family, frequently studied alongside incretin agonists.
How These Differ From Prescription GLP-1 Products
These are research-grade reference compounds — not prescription products. They are supplied for in-vitro and laboratory investigation of incretin signaling and are not approved for human use. Compounds studied for the somatotropic axis appear in our GH Stimulators collection.
Comparing GLP-1 Research Peptides
| Compound | Agonist type | Receptors studied |
|---|---|---|
| TZ-2 | Dual | GLP-1 + GIP |
| RT3 | Triple | GLP-1 + GIP + glucagon |
| Cagrilinitide | Amylin analog | AMY1–AMY3 |
Frequently Asked Questions
What are GLP-1 research peptides? They are incretin-pathway compounds studied for glucose-homeostasis and energy-balance signaling through GLP-1, GIP, glucagon, and amylin receptors.
What is the difference between dual and triple agonists? The number refers to how many receptor types a compound engages — TZ-2 engages two (GLP-1/GIP), while RT3 engages three by adding the glucagon receptor.
Are GLP-1 research peptides the same as prescription GLP-1 medications? No. These are research-grade reference compounds for laboratory use only, not approved pharmaceutical products.
What is Cagrilinitide studied for? Cagrilinitide is an amylin-receptor analog researched for satiety and gastric-motility signaling, often in combination models with incretin agonists.
Are these approved for human use? No. Every compound in this collection is supplied strictly for laboratory research use only.
