The extra receptor is the point of the comparison
GLP-RT3 20 mg is discussed in work on GLP-1, GIP, and glucagon-receptor signaling together. GLP-2TZ 15 mg is discussed in work on GIP and GLP-1 receptor pharmacology, without that third glucagon-receptor arm.
The labeled amounts are different too: 20 mg versus 15 mg. Do not treat the catalog amounts as matched doses. This page does not provide a dose.
Separate tasks, separate milligram results
GLP-RT3 task 149759, analysis May 11, 2026, prints 22.99 mg and purity 99.576%. GLP-2TZ task 171262, analysis June 23, 2026, prints 17.37 mg and purity 99.685%. Both results are milligrams, and they still describe different samples on different dates.
Use the task number on the vial you received. A May result does not describe a June sample.
Which listing to open
GLP-RT3 20 mg is $84.99. GLP-2TZ 15 mg is $64.99. Buy one, get one 50% off on either. If the question is GLP-1 receptor pharmacology alone, GLP-1SG 15 mg at $54.99 is the closer listing.
