Comparison of GLP-1 receptor agonist research peptides most-cited in Texas metabolic-science bench work.
Written for the Texas research community, this reference brings together the documentation Texas metabolic-research labs compare on GLP-1 agonist references that labs from Austin to Houston, Dallas to San Antonio typically request when qualifying a new lot. Every batch we dispatch from our Texas warehouse ships with the analytical documentation described below.
| Compound | Receptor targets | Half-life (research) |
|---|---|---|
| Liraglutide | GLP-1 | ~13 hours |
| Semaglutide | GLP-1 | ~7 days |
| Tirzepatide | GIP + GLP-1 | ~5 days |
| Retatrutide | GIP + GLP-1 + GCG | ~6 days |
