GLP-1 Compounds

Incretin receptor agonists supplied as lyophilized powder for laboratory research use only. This category covers single, dual, and triple receptor agonists, allowing comparative work across the full range of incretin pharmacology within a single verified supply chain.

The compounds here differ in how many receptor targets a single molecule engages. Semaglutide is a selective GLP-1 receptor agonist, engaging one target. Tirzepatide is a dual agonist, adding GIP receptor activity. Retatrutide is a triple agonist, adding glucagon receptor engagement on top of both. Researchers commonly run all three as a comparative series to isolate the contribution of each receptor arm.

Every lot is independently assayed by Janoshik Analytical before listing, with identity and purity confirmed by HPLC and molecular weight confirmed by mass spectrometry. The lot number on each vial matches a published report in our COA Library, and each product page links directly to the Janoshik verification record for its specific lot. If you are not sure what to look for in those reports, see how to actually read a Janoshik COA.
