We're ordering this for diabetes studies in teh pipeline — the dual GIP/GLP-1 mechanism is what we need, and the 98% purity via HPLC is tight enough for our assays, with the molecular weight coming in at 4813.45 g/mol, which we've verified against the reference standard. It's a white powder, stored at -20°C long term, and we usually have stock, but confirm lead time — (check the 2-4 week window if we're pushing for fast start).
The CAS number is 2023788-19-2, and the molecular formula C225H348N48O68 checks out against what we've seen form other suppliers, but what sold me is the consistent purity across batches — better than reagent grade for this kind of work, and the HPLC data on the COA from the last order showed no major impurity peaks. Also, the MOQ is reasonable for our budget, so we're not sitting on excess inventory.
Most buyers go with the 10mg vial for initial testing, but we're ordering the 50mg format since we've got a longer study window — the powder is easier to handle in that size, and the packaing is sealed under argon, which is a concrete detail I've seen matter when storage conditions aren't perfect. It's basically a standdard lyophilized peptide, so reconstitution is straightforward, though solubility is still listed as 'to be determined' — we'll use DMSO or PBS as a starting point.
One thing this isn't suited for is oral dosing in vivo — it's strictly for in vitro or injectable research, so don't let anyone assume otherwise. The HS code is 2934.99.9001, which we've used before for customs, and the price per mg works out to about $0.85 or so depending on the batch, which is competitive given the purity.
Anyway, the dual receptor binding — greater affinity for GIP than GLP-1 — is what sets it apart from other GLP-1 analogs we've tested, and the hyperglycemia reduction in preclinical data is solid, though I'd note the storage at -20°C is non-negotiable for long-term stability. We've got the cold chain covered in the lab, so no issues there.
Lead time depends on quantity, but for most bulk orders we can ship within 7–14 business days after payment confirmation. If you need it faster, just let us know and we can check stock availability.
Yes, we provide a COA for every batch, including HPLC purity results and other specs like appearance and molecular weight. Just request it with your order and we'll include it in the shipment.
Our MOQ is typically 1 gram for standard orders. If you need a smaller amount for initial testing, we can discuss that on a case-by-case basis.
Store it at -20°C for long-term stability, and keep it sealed and away from moisture. For short-term use, it can be kept at -4°C, but avoid repeated freeze-thaw cycles.
That HS code applies generally to heterocyclic compounds like peptides, but customs classifications can vary by country. We recommend checking with your local customs office to confirm it's accepted for your specific import.
