The purity hits ≥98% by HPLC consistently batch to batch, which is actually better than some reference standard we've tested against—it means fewer side products to account for in your assays (usually 2-4 weeks for those to clear).
We've been running this semaglutide in our lab for about six months now, and what it does is save us from having to re-synthesize after failed purifications. The 4113.6 g/mol molecular weight means you get pretty much exactly what the spec sheet says, no surprises when you run your own MS.
Ordering is straightforward—MOQ is 5 vials for custom packaing, but we usually go with the 50mg bulk vial because of that it's easier to aliquot. You'll need to store it at -20°C and keep it away from light, which is standerd for any lyophilized peptide, but don't expect it to hold up if you leave it on the bench overnight.
One thing I'd mention: it's not ideal for in vivo work unless you're just doing solubility testing, since the formulation isn't optimized for injection. Most buyers go with the 10mg vials for cell-based assays, but teh 5mg size works fine if you're just reconstituting small batches.
Anyway, the COA comes with every batch, and we've got the HPLC traces on file if you need to see the raw data. Lead time is usually 20 days or so form order confirmation, but confirm with your rep if you're in a rush—sometimes our company have stock ready to go.
Our MOQ is typically 10 grams for the lyophilized powder, but we can adjust it depending on your specific needs.
We ship within 3-5 business days after order confirmation, and express shipping takes around 5-7 days worldwide.
Yes, every batch comes with a COA from our in-house lab, showing the exact HPLC purity results.
Absolutely, we offer customizable packaging including vials, ampoules, or bulk containers—just let us know your preferred format.
We ship it with ice packs to keep it cool, but once you get it, store it at -20°C in a freezer, away from light, to keep it stable.
