About This Test

🔍

What is blind testing?

You do not need to tell us which of the three GLP-1 peptides you suspect to be in your vial. Our lab will identify the compound, measure its amount, and determine purity — without any prior declaration from you. In the case of a mixture of all three, ID and amount of each will be analyzed.

This is our most popular GLP-1 test. It covers the three most widely circulated GLP-1 receptor agonist peptides in the research market. A single submission gives you identity confirmation, quantification, and purity data — plus a published batch report you can link to.

Compounds Covered

Semaglutide
GLP-1 receptor agonist
Tirzepatide
GLP-1 / GIP dual agonist
