We've been burning through the 5mg vials faster than expected, and the 10mg bulk packging actually works out to about $0.18 per mg versus $0.35 for the smaller sizes — that's a for the volume we're running.
It basically handles the GLP-1 receptor activation we need for the metabolic assays, and the ≥99.9% HPLC purity means we're not chasing ghost peaks in the LC-MS runs.

The white powder dissolves cleanly in water at room temp, though you'll want to buffer it quickly because the solubility drops off below pH 4 — we usually have stock, but confirm lead time if you need more than 50 grams.

Storage is 2-8°C in a dry enviornment, and we've had batches sit for 18 months without degradation, but don't freeze it or you'll get aggregation issues.

CAS 910463-68-2, molecular weight 4113.6 g/mol, and the COA comes with each lot — teh 24-month shelf life is accurate if you keep the desiccant packs in sealed vials.
Not great for oral dosing studies because the bioavailability is basically zero without the absorption enhancers, but for injectable or cell-based work it's solid.
