We've got 200 vials on hand right now, with another 500 coming in about two weeks — teh cold chain is already set for 2-8°C shipping, so no delays there. Each vial is packed in a sealed foil pouch with a desiccant, and we're using those temperature-logged shippers you asked about, which usually arrive within 5-7 business days.
The MW is 4813 g/mol, CAS 2023788-19-2, and it's a at 20mg per vial with 99% purity verified by HPLC — which is pretty standerd for pharmacy-grade matrial but better than what most reagent supliers push. We include a COA with every batch, and the peptide backbone has those fatty acid modifications that improve solubility, so reconstitution is cleaner than with some other GLP-1 analogs we've handled.
It's primarily for obesity and diabetes research models, but some labs use it in combination studies with tirzepatide or other incretin mimetics — just don't expect it to work in cell-free systems above 10µM because aggregation starts becoming noticeable. The 20mg vial size is actually a sweet spot for most dose-response work, though if you're running high-throughput screens you'll want to order in bulk since MOQ is 50 vials anyway.
We usually have stock for custom labeling, but confirm lead time if you need more than 200 vials — the turnaround is about 10 days or so for OEM printing.
