Comparison / GLP-1 Class
The GLP-1 class, compared.
Three reference standards in the GLP-1 class: single, dual, and triple agonist. How they differ in receptor activity and research applications.
Receptor activity
- Semaglutide — single agonist at the GLP-1 receptor.
- Tirzepatide — dual agonist at GIP and GLP-1 receptors.
- Retatrutide — triple agonist at GIP, GLP-1, and glucagon receptors.
At a glance
| Compound | Class | Kelowna price |
|---|---|---|
| Semaglutide | GLP-1 | $75 CAD (5 mg) |
| Tirzepatide | GIP + GLP-1 | From $99 CAD |
| Retatrutide | GIP + GLP-1 + glucagon | From $139 CAD |
Research context
Each successive generation adds a receptor target. For comparative research across the class, maintaining reference standards of all three at −20°C simplifies side-by-side assay work. Lumera Labs stocks all three at HPLC-verified purity.
