We had a lab last month running a GIP/GLP-1 dual activation study, and they needed consistent vials across three separate orders without any drift in purity or solubility.

It's ≥99% by HPLC with a molecular weight of 4813—pretty much spot on for the CAS 2023788-19-2—and it dissolves clean in water or DMSO, though storage at -20°C is non-negotiable for stability.

Most buyers go with the 10mg vials for dose-response work, but honestly, it's not suited for chronic in vivo studies without proper formulation, as teh peptide degrades if you leave it out too long.
5mg to 60mg vials are avaliable, and we usually have stock for the 10mg and 15mg sizes, but confirm lead time for 60mg—sometimes it's 20 days or so.

5, we provide a COA with every batch, and payment terms are standdard net 30 for established accounts, though new orders require a wire transfer upfront.

Shiping to UK addresses takes about 5-7 business days via courier with dry ice, and we've got the documentation for customs clearance sorted.
MOQ is typically 100 vials, but we can adjust based on the packaging size you choose—just reach out for custom quotes.
Yes, we include a CoA with HPLC purity data for every batch, so you can verify the ≥99% purity yourself.
Standard lead time is 5-7 business days after payment, plus shipping time to the UK—usually 3-5 days via express courier.
We currently offer 5mg, 10mg, 15mg, 30mg, and 60mg vials, but we can discuss other sizes for bulk orders.
Store them at -20°C in a freezer, away from light and moisture. Once reconstituted, keep refrigerated and use promptly.
