If you're comparing suppilers for these GLP-1 analogues, what makes this worth a look is the 99% purity with HPLC data — most of the cheaper sources I've seen run 95-97% and don't always share the chromatograms.
The CAS is 2381089-83-2 for semaglutide, and it's a that reconstitutes cleanly in bacteriostatic water if you handle it right — store at -20°C long-term or 2-8°C for a few weeks, and don't freeze-thaw more than once or twice.
We usually stock 10mg, 15mg, 20mg, and 30mg per vial, ten, and you can customize sizes if your protocol needs something odd (check lead time on those). Most buyers go with the 10mg or 15mg for typical dosing ranges.
Basically, this isn't for human use — it's research grade, so don't expect it to match pharmacy formulations for injection. The white powder itself is fine, but you'll need your own sterile handling gear if you're reconstituting.
Also, delivrey from teh UK warhouse is about 5-7 working days domestically, give or take, and we include COA with each batch (usually emailed within 24 hours of dispatch). One thing a buyer might not think to ask: we do spot-check lyophilization cake appearance, so you won't get collapsed plugs that dissolve unevenly.
We've had a few labs switch from Chinese suppliers because documentation here is cleaner — less hassle with customs, and the purity variance is tighter than what they were seeing at 95-97%.
