What it does in practice is basically mimic your natural GLP-1 hormone but way longer-acting — we're talking hours instead of minutes, so researchers use it for studying insulin secretion patterns in type 2 diabetes models without teh constant redosing.
Purity hits ≥98% by HPLC (we run every batch through that, not just a spot check), molecular weight sits at 4113.58 g/mol, and it's a white powder that dissolves fine in water — store it at 2-8°C in the dark or it'll degrade faster than you'd think.
You'll get 10mg per vial (that's usually enough for a decent dose-response curve in rodent studies) and each batch comes with a COA showing retention time, peak area, and the sequence verification — the full amino acid chain is on the spec sheet but honestly most buyers just check HPLC purity and retest date.
For the record, this is research use only — not for human or veterinary applicaion, and the 10mg format is better suited for in vitro work or small animal trials than large-scale synthesis, so don't plan on scaling up direct form this vial.
Also, we've got a retest policy that covers 12 months from dispatch (just keep it sealed and refrigerated), but if you need a fresh COA past that, we'll run a new HPLC for like £30 or so — roughly a week turnaround.
Anyway, most labs find the ≥98% purity holds up fine for their protocols, but if you're doing something really sensitive like cell-based assays where trace impurities matter, you might want to request the batch-specific impurity profile — we usually have that on file.
