Actually, we've been handling this peptide for a while now, and the CAS 2023788-19-2 is the one you'll want for your GIP/GLP-1 dual agonist work—it's pretty much the standard for metabolic research these days, and we typically stock it as a white to off-white powder with purity at 99% or better, though I'd double-check the COA for your specific batch since we sometimes see slight variations in the off-white shade.
molecular weight is 4813.48 g/mol, and the formula C225H348N48O68 is what you'd expect for a compound this size—most buyers go with the lyophilized powder form because of that it's easier to handle for reconstitution, but we also offer it in smaller vials if you're only running a few assays (usually 10mg or 50mg per vial depending on your lab's setup).
One thing that catches people off guard is the storage requirement—it needs to be kept at 2-8°C and protected form light, which is pretty standard for these peptides but we've had labs accidentally leave it out at room temperature for a day or so, and while it's usually still fine, the activity can drop noticeably if you do that repeatedly.
For ordering, the MOQ is typically 1 gram for wholsale, but we can do custom synthesis if you need a specific salt form or purity grade—just be aware the lead time for custom orders is about 20 days or so, while stock orders ship within 3 business days and we include the HPLC and mass spec data with every shipment as standard.
It's not ideal for in vivo work unless you're really careful about endotoxin levels—we've had a few researchers use it in cell-based assays and then try to switch to animal models without checking the endotoxin specs, which is a mistake since our standard grade is pharmaceutical grade but not sterile-filtered for injection.
Also, the 5L drum is easier to handle if you're doing bulk reconstitution, but for most labs the 1g or 500mg bottles work fine, and we always recommend ordering a small test batch first (like 100mg) to confirm it performs in your particualr buffer system before committing to larger quantities.
Our MOQ for this product is typically 10 grams, but we can discuss smaller quantities for first-time buyers or specific research needs.
Standard lead time is 5-7 business days after payment confirmation. Rush orders can be arranged with prior notice.
Yes, each batch comes with a detailed COA confirming ≥99% purity and identity verification, along with other quality specs.
Store it at 2-8°C in a tightly sealed container, protected from light. Avoid repeated freeze-thaw cycles to maintain stability.
Yes, we offer custom packaging options like smaller vials or bulk bags, and can add your lab's label for an extra fee.
