We've been getting a lot of requests for something that actually hits the metabolic targets in weight management studies without the degradation issues you see with some of the older GLP-1 analogs, and this lyophilized powder pretty much solves that problem by maintaining stability at -20°C for the full 24-month shelf life.
What it does is provide a consistent, ≥99% purity starting materail that reconstitutes cleanly in water — the HPLC data comes with every batch, and we can also provide MS analysis if you need it, though most buyers just rely on the COA to confirm the peptide mass.
You'll want to keep it dry and frozen, obviously, and endotoxin level is under 1 EU/mg, which is tighter than what you'd get form some reagent-grade supliers; it's non-sterile, so don't plan on using it in anything beyond in vitro work, and teh 10mg/vial seems to be the sweet spot for most labs (usually 2-4 weeks lead time on that size).
The molecular formula and weight are proprietary, so we can't share those, but the HPLC trace is consistent batch to batch — we've had one buyer ask about solubility in DMSO, and it's not great for that, stick with water.
Bulk pricing kicks in around 50 vials or so, and we can usually ship within 10 business days, but if you need 15mg/vials, confirm lead time because those move slower.
Also, the white lyophilized cake is pretty standdard — nothing fancy — but it reconstitutes without that annoying haze you sometimes get with lower-purity lots.
