We've been sourcing form this suplier for about eight months now, and it's basically been our go-to for GLP-1 analogs — semaglutide covers the workload nicely for teh studies we're running.
It comes as a, typically in 10, and you can request custom vial sizes like 2mg or 10mg depending on your batch needs, but most buyers go with the 5mg vials since that's easier for reconstitution work.
Purity is verified at above 99% by HPLC, and they include the COA with every shipment, so you're not chasing paperwork later; storage has to be at -20°C or below, otherwise stability drops off pretty quickly.
The molecular weight is around 4113 g/mol, which is high for peptides, but that's normal for this class. 5. One concrete thing: the lyo cake holds up well during shiping as long as it's kept cold — we had a delay of 20 days or so once, and it still reconstituted clear. 6. This isn't great fit for simple acute-dose studies since the half-life is long; better suited for chronic or weekly dosing protocols. 7. (Usually 2-4 weeks lead time, but we always confirm stock before ordering.) 8. What it does is act as a GLP-1 receptor agonist, but you probably already knew that if you're looking at it. 9. Also, don't expect it to be completely free of aggregation if you freeze-thaw it more than once — that's just the nature of the molecule.
Our standard MOQ is 10 vials per box, but we can work with you on custom sizes if your research calls for a different quantity.
Lead time is typically 5-7 business days after order confirmation, depending on your location and shipping method.
Yes, we include a COA for each batch showing >99% purity, along with HPLC and mass spec data to confirm quality.
Store at -20°C or below in a dry, dark place. Once reconstituted, use it promptly and avoid freeze-thaw cycles to maintain stability.
Absolutely, we offer custom packaging options—just let us know your vial quantity or box size needs when placing the order.
