Common GLP-1 peptide blind test (Semaglutide, Tirzepatide and Retatrutide)

Most popular test of GLP-1 peptides – blind test of semaglutide, tirzepatide, and retatrutide. Providing you with ID, amount and peptide purity of your sample.

With blind testing, you do not need to tell us which of the three peptides you suspect to be in your vial. The test will identify the peptide, all the while accurately measuring it’s amount in the vial and peptide purity. In case of a mixture of the three, ID and amount of all will be analyzed.

The default test is meant for a finished vial with lyophilizate. In case you want to test raw peptide powder, please choose „Raw Powder“ option from additional services.

You can find the test details in the parameters section below.
