He’s been sourcing from this particualr supplier for about six months now, and the 99% purity holds up consistently batch after batch—they run HPLC on every lot, though he usually just asks for COA if he’s curious about the exact impurity profile. Molecular weight is 4813.47 g/mol, and it’s a white powder that stores at 2-8°C in a dry enviornment, which is pretty standard for lyophilized peptides of this class.
Most of the labs he works with use it for in vitro metabolic pathway studies, not for anything in vivo since it’s strictly research-grade. It’s basically a dual agonist—GIP and GLP-1—so the binding affinity at those receptors is what drives the experimental design, and the 225-residue sequence means you need to reconstitute it carefully to avoid aggregation.
They offer 1g, 10g, and 1kg packaging, but he’s found the 10g drum is the sweet spot for a quarter’s worth of assays without tying up too much budget. Lead time is typically 20 days or so, though he’s had a rush order come in at 14 when he called ahead.
Actually, one thing he noticed early on is the powder has a slight static charge when you open it—so worth using an anti-static spatula to avoid losing material during weighing. The CAS is 2023788-19-2, but that’s just a formality for the lab inventory system.
It’s not great for anything involving long-term stability at room tempearture; you really have to keep it refrigerated or you’ll see degradation within a month. Some buyers go with the 1g pack for single-use studies, but he prefers the 10g because the per-gram cost drops by about 15%.
He usually orders a bulk batch once a year and checks the TDS on arrival—never had a mismatch yet, but they did send one shipment with the vial labels slightly misaligned, which was minor.
We offer flexible packaging options at 1g, 10g, and 1kg, so there's no strict MOQ—you can start with as little as 1 gram for initial research.
Yes, every batch comes with a COA that verifies the ≥99% purity, along with HPLC and other test data upon request.
Store it at 2-8°C in a dry environment, away from moisture and light. Keep the container sealed tightly to preserve the white powder form.
Standard lead time is 5-7 business days for 10g orders and up to 14 days for 1kg, depending on stock availability. We'll confirm exact timing when you place the order.
We can accommodate custom packaging for bulk orders, but the standard options are 1g, 10g, and 1kg. Just let us know your needs, and we'll work it out.
