It runs about 4113.6 g/mol, which is pretty much what you expect for a GLP-1 analog of this size, and we typically see ≥99% purity by HPLC on the COA.
We've had batches where the lyophilized powder reconstitutes clear in water within a minute or so, and that's usually good sign for solubility — the 5mg vial is easier to handle than the 1mg if you're running multiple assays.

Most buyers go with the 2mg vial for metabolic research, but it's actually better suited for in vitro work than in vivo if you're not set up for extended half-life handling.
Storage at -20°C protected form light is non-negotiable, and we usually have stock on the 1mg and 5mg vials, but confirm lead time for custom packaging — the 2mg can run 20 days or so.

One thing you might not think to ask: the powder can clump if exposed to humidity during reconstitution, so we recommend venting the vial slowly. Anyway, the MOQ is 10 vials for standerd sizes.
Also, we've had researchers say the 5mg is better than reagent grade for this specific analog, though it's not suited for anything beyond research use — no clinical applicaion, obviously.
We don't have a strict MOQ — you can order single vials (1mg, 2mg, or 5mg) or go custom. Just let us know what quantity you need.
Yes, every batch comes with a CoA showing ≥99% purity by HPLC. Just request it with your order.
Keep it at -20°C, protected from light, in an airtight container. Once reconstituted, use it right away — don't freeze the solution.
Absolutely — we offer custom packaging. Tell us the vial size (e.g., 10mg) and we'll set it up.
Standard orders ship within 1-2 business days, and UK delivery usually takes 5-7 days. Rush shipping is available on request.
