Characterization

What it is, stated plainly.

What it is

A synthetic 39-amino-acid peptide. It is a triple agonist — it binds and activates the GIP receptor, the GLP-1 receptor and the glucagon receptor, all three of which are class B G-protein-coupled receptors. Published work places it in the metabolic-signalling literature, where incretin-receptor pharmacology is the subject.

How a lot is verified

Purity assayed by third-party HPLC and net content (mg per vial) measured by the lab, with a certificate of analysis published where tested. A lot that misses spec is rejected.

Handling & storage

Supplied as a lyophilized powder. Store at −20°C, desiccated and protected from light. Handled per the receiving laboratory's procedures. Not for human consumption.
