We’ve got a client running metabolic pathway assays who needs this specifically for GIP/GLP-1 dual agonist work in type 2 diabetes models — they’re using it at 10nM to 100nM in cell-based receptor activation studies, and the 99.9% purity by HPLC is what makes that feasible without off-target noise.

CAS 2023788-19-2 is correct, MW is 4813 g/mol, and it’s pharmacy grade — not research grade — which means tighter tolerance on residual solvents and endotoxins than what you’d get from a standard peptide supplier, usually within 2-5 ppm for most contaminants.

Packaing is 10mg per vial, 10, and the MOQ is 10 vials, so you’re not stuck ordering a full gram if you’re just validating a protocol or running a small pilot — we usually have stock, but confirm lead time for orders over 50 boxes (typically 2-3 weeks).


Documentation includes a full COA with HPLC trace, mass spec confirmation, and residual solvent data — they don’t always provide endotoxin report upfront, but it’s availble on request, and our company can do a 3rd-party HPLC if your QA insists.

Payment is standard net 30 for approved accounts or wire transfer for first orders — shiping is via FedEx priority or DHL express, with dry ice and tempearture logging for the lyophilized powder, which is critical because this peptide degrades above 4°C after reconstitution.

One thing to watch: this isn’t suited for in vivo work without further formulation — it’s a lyophilized powder meant for reconstitution in sterile water or PBS, and the solubility is pretty much fine at 1 mg/mL, but we’ve seen some batches need gentle warming to dissolve completely, so account for that in your prep steps.
Our MOQ is 10 vials, which comes as one box. So you're looking at a minimum of 10 vials per order.
Yes, we include a COA with every batch showing the 99.9% purity and other specs. Just ask if you need additional documentation like an HPLC report.
We standardize at 10mg per vial, 10 vials per box, but we do offer customization for bulk orders. Let us know your specific vial size needs and we'll work it out.
For stock items, we usually ship within 3-5 business days. Larger custom orders might take 1-2 weeks depending on volume and packaging specs.
Keep it in a cool, dry place away from direct sunlight, ideally at 2-8°C if you want long-term stability. The vials are sealed tight, so just reseal after use.
Unbelievably fast shipping and professional handling. The order was dispatched promptly and arrived well ahead of the estimated schedule, which was a fantastic start. Upon inspection, the packaging was secure, discreet, and clearly labeled, demonstrating a high level of care. Communication from the supplier was clear and proactive throughout the process, answering preliminary queries efficiently. The overall service experience felt streamlined and reliable. While the specific application for research is pending, the initial presentation and the efficiency of the transaction are highly commendable. This level of logistical efficiency and professional service is precisely what is needed for sourcing materials, making the procurement process remarkably smooth and stress-free.
