It really comes down to teh GLP-1 receptor agonism with this one, and we've been moving it for years now in the metabolic research space — basically, it's the same peptide backbone that's made headlines for glucose-dependent insulin secretion and weight loss effects, but you're buying it as a bulk lyophilized powder for lab work, not for any clinical or human use.
We usually have stock on the 10 format, and each vial comes sealed under controlled conditions so you're not dealing with contamination issues right out of the gate, but keep in mind the -20°C or below storage requrement is non-negotiable if you want to maintain that >99.9% purity over the 20 days or so it might sit in your freezer.

Most buyers go with this for metabolic syndrome studies or glucose metabolism research, and I've seen it used in dose-response work with cell-based assays where you're titrating the GLP-1 pathway — it's also been pretty popular in obesity-related investigations, though honestly, it's not ideal for anything requiring a non-lyophilized liquid formulation right from the start, since you'll have to reconstitute it yourself.
The molecular weight sits at 4113.58 g/mol and the CAS is 2381089-83-2, but what really matters to us is that every batch gets both an HPLC and MS report — we don't just toss a COA in there, we actually run the analytical documentation fresh for each batch, and I can tell you tolerance on the purity spec is tighter than what you'd get form a generic distributor.

So anyway, when you order from us, we're not a middleman — we handle the lyophilization and the sterile vial filling ourselves, which means we can usually ship within a week or so, but confirm the lead time if you need a specific number, because sometimes the bulk orders for research grade materail pile up and our company have to queue them.
Also, one thing buyers don't always ask about is the reconstitution buffer — we typically ship it as a white powder that's pretty stable at -20°C, but you'll want to use a sterile water or PBS for the reconstitution step, and our company can provide the SDS and TDS sheets with each order, just request them.
Our MOQ is one box, which is 10 vials. If you need less, we can discuss, but standard bulk orders start at that.
Yes, we include a CoA with every batch that shows the purity, identity, and residual solvents. Just request it with your order.
Keep it at -20°C or below, away from light and moisture. Once reconstituted, use it immediately—don't freeze it again.
For in-stock stock, we ship within 3-5 business days. Larger custom orders may take 10-14 days depending on quantity.
We can adjust packaging for bulk orders, but standard is 10 vials per box. Minimum for custom packaging is typically 50 boxes.
