We’ve been moving these vials out of cold storage at a steady clip—roughly 200 units a week as of last month, so stock is solid but we usually confirm lead time for orders over 50 boxes. The 10mg vials are the most common pick for metabolic assays, though the 30mg concentration is gaining traction with labs running longer dose-response studies. Each box holds 10 vials, shipped with dry ice and a temperture logger, so you’ll know it stayed below -20°C the whole way.
It’s a, ≥99% purity by HPLC, and molecular weight sits at 4731.33 g/mol—that’s a big peptide, so reconstitution needs care with sterile water or PBS. The CAS is 2381089-83-2, and the formula runs C221H342N46O68, which basically means it’s a GLP-1 receptor agonist, not a triple agonist like some other peptides on the market. We don’t use it for anything beyond research use only, so don’t expect it in clinical settings.
What you actually get when ordering is a sealed vial with a rubber stopper and aluminun crimp, lyophilized cake that looks off-white (slightly fluffier than you’d think). Most buyers go with teh 5mg or 10mg for rodent studies—the 40mg vial is overkill unless you’re pooling samples. Our COA comes with each batch, and we’ll send an SDS if requested, but the storage spec is non-negotiable: -20°C or below, or it degrades faster than you’d like.
2381089-83-2 is the CAS, and purity is typically 99.2% on recent batches—not always 99.5%, but it’s tighter than reagent grade for this. The molecular weight can vary by a few daltons depending on the counterion (acetate or TFA), and we don’t always specify which salt form is used unless you ask. Anyway, the 20mg vial is easier to handle for reconstitution than the 5mg—less powder stuck to the walls.
One thing that’s not obvious: the lyophilized powder can be hygroscopic, so open it in low-humidity enviornment or you’ll get clumping. We’ve had buyers try to reconstitute with saline, but it’s not ideal—use sterile water or the buffer recommended in the protocol. Also, it’s not suited for oral dosing formulations; this is strictly injectable-grade peptide for research.
We require a minimum of 1 box, so that's 10 vials. You can mix concentrations within the same box if needed.
Lead time is typically 3-5 business days for stock orders. For larger quantities or custom packaging, it can stretch to 7-10 days.
Yes, a COA is included with every order showing ≥99% purity and the actual test results for that batch.
We can customize concentrations, but we'd need a minimum of 50 vials per custom batch. Standard sizes are 5mg, 10mg, 20mg, 30mg, and 40mg.
Store at -20°C or below in a freezer. Once reconstituted, use it within 30 days if kept refrigerated.
