99% or better by HPLC is teh floor we hold every batch to, and that mechanism hitting GLP-1, GIP, and glucagon simultaneously is what makes it interesting for metabolic work. We've seen researchers push it in weight management protocols, but honestly it's not ideal for acute dosing studies — the half-life in that lyophilized state is pretty long once reconstituted.
The 3872.3 g/mol molecular weight means you're dealing with a fairly large peptide, so filter-sterilized solution before lyophilization is critical to avoid aggregation — we do that as standerd, and endotoxin stays under 0.1 EU/mg. Most buyers go with the 10mg vial for, but the 5mg option is easier if you're running small pilot batches.
Storage is straightforward but unforgiving: -20°C protected form light, and we've tested shelf life at 24 months under those conditions, though we usually have stock turn faster than that. is basically what you expect — no clumping issues if it's kept dry, and reconstitution in sterile water or saline takes about 30 seconds.
Ordering is typically in 10-vial boxes, and our company can mix 5mg or 10mg per vial depending on your batch size. Lead time is usually 10-14 working days or so, but check it — sometimes we're faster if stock is on hand. MOQ is one box, and we include the COA with each shipment (HPLC traces, endotoxin data, appearance check).
Our standard MOQ is one box, which contains 10 vials. You can choose either the 5mg or 10mg per vial option.
We usually ship within 3-5 business days after order confirmation. For larger orders, it might take a bit longer, but we'll keep you posted.
Yes, we include a COA with every shipment that shows HPLC purity ≥99%, endotoxin levels under 0.1 EU/mg, and sterility test results.
Store it at -20°C, protected from light, just like the unopened vials. Once reconstituted, use it immediately—don't freeze the solution.
We can customize the vial label or box with your lab's information, but the minimum order for custom packaging is 100 boxes. Just let us know your needs.
