That 99.7% purity is where it really starts to matter — we've had customers run their own HPLC on our batches and it consistently comes back within tolerance, usually right around 99.8% actually, so you're getting a tight margin there.
What this means in practice is fewer failed runs and less time troubleshooting unexpected results, and we include a Certificte of Analysis with every single vial so you can see the actual chromatogram and residual solvent data for that specific lot.
We hold back a small sample form every production run for a full 12 months after shipment, so if you ever need a retest or a second opinion on stability, our company can pull that same batch and run new assays for you — no charge for the first retest within six months.
Ordering is pretty straightforward: minimum order is 10 vials, but we usually have stock on hand so lead time is about 5 business days or so depending on your location, and we ship with cold packs and temperture loggers to keep it stable at 2-8°C whole way.
The CAS number is 2023788-19-2, and the molecular weight is roughly 4113 g/mol — I always mention that because some researchers need to cross-reference for their dosing calculations, and it's not always on the front page of other supliers' sites.
One thing that catches people off guard is that this is strictly for research purposes only — we don't recommend it for any clinical or human use, and honestly, we've had a few buyers try to pivot it toward that and we just can't ship those orders.
We don't have a strict MOQ—you can order as few as 10mg vials to start. For larger quantities, just let us know your volume and we'll work out pricing.
Standard lead time is 3-5 business days for processing, then shipping depends on your location. We ship from our warehouse in China via express courier, usually 7-14 days worldwide.
Yes, we include a COA with every batch of Semaglutide—it shows the HPLC purity reading at 99.7% and other specs like molecular weight and appearance. Just request it when you order.
Sure, we can customize packaging to your needs—say 20mg or 50mg per vial, or bulk in larger containers. Minimum for custom is usually around 100 vials, but we're flexible.
Keep it in a refrigerator at 2-8°C, away from light and moisture—the original vial is fine if sealed. Unopened, it stays stable for 2 years; once reconstituted, use it within a few days.
