It's the GLP-1 analog with that 99.7% purity we've been seeing in the literature, CAS 2023788-19-2, and honestly for the bulk pricing on this batch it made more sense than sourcing smaller lots form different suppliers—we usually have stock but confirm lead time if you need it fast, because sometimes it's 20 days or so. The is what you'd expect, and the molecular weight is 4113.58 g/mol which is hefty but manageable in solution.
We're getting it in the standard 10, which works for most of our runs, and the storage is straightforward at 2-8°C protected from light—basically just keep it in the fridge drawer away from the window. What it does is hold up well for extended studies if you're careful with reconstitution, but it's research grade only so don't even think about clinical work with this.
The HPLC data on the COA came back tight across all three lots they sampled, and the peptide content is consistent enough that we're not seeing the variability you get with some cheaper sources. One thing a buyer might not think to ask is that teh powder can clump if it's exposed to moisture during handling, so we're ordering the sealed vials with desiccant packs included.
For most of our protocols, this is better than reagent grade for dose-response work because the purity threshold cuts down on off-target effects, but it's not suited for anything involving cell viability assays where you need absolute sterility—that's a different spec entirely. We've got enough on order to cover about 2 months of normal usage, maybe 3 if the team scales back a bit.
The supplier mentioned they can do custom packaging for bulk orders if we need it, but for this round the standard box format is fine since we're just running comparative studies. Anyway, lead time was roughly 2-4 weeks (check with logistics on the exact date), and the price per vial dropped enough that it was actually cheaper than the 5mg version from our last suplier despite the higher molecular weight.
Our MOQ is 10 vials per box, so you'd need to start with at least one full box. If you need larger volumes, just ask—we can scale up from there.
Yes, every batch comes with a CoA showing the 99.7% purity, appearance, and molecular weight matching C187H291N45O59. Just request it with your order.
Keep it at 2-8°C in the original packaging, protected from light. That white powder is stable under those conditions for research use.
Our standard is 10 vials per box, but we can discuss custom vial counts or sizes for bulk orders. Lead time may shift a bit depending on the request.
For stock orders, lead time is usually 5-7 business days after payment. Custom packaging or larger volumes might take 2-3 weeks—we'll confirm when you place the order.
