We see plenty of buyers struggling with batch-to-batch variability in peptides, which is why every batch of this one goes through HPLC verification showing at least 99% purity — and we back that with a full COA you can review before shiping.
The white powder comes lyophilized and we normally keep stock at -20°C for long-term storage, but for short-term handling during reconstitution, it’s pretty stable at room temperature for a few hours (just don’t leave it out overnight).
Actually, one thing researchers don’t always ask is our retest policy — we’ll run a fresh HPLC and endotoxin test if the material has been in your fridge beyond 12 months or so, which saves headaches on expired certifcates.
Molecular weight comes out to about 4813.45 g/mol, and CAS is 87805-34-3, but what really matters for consistency is that we keep the production process locked — same buffer, same lyophilization cycle every time, batch after batch.
For most labs studying metabolic pathways or diabetes models, teh 2mg vial size works, but we also offer 5mg and 10mg options depending on your protocol; OEM labeling is availble if you’re running multiple projects.
Lead time is usually 7-10 business days for in-stock items, and we ship with dry ice and temperture loggers — you’ll get a tracking number with the SDS and COA included in the package.
Our MOQ is 10 grams per order. We can adjust for larger research projects, but 10g is the standard minimum.
Yes, every batch comes with a COA showing ≥99% purity verified by HPLC. We can also share third-party test results upon request.
Store it at -20°C for long-term stability. For short-term use, keep it in a cool, dry place away from light. Avoid freeze-thaw cycles.
We can label vials with your research project reference or adjust packaging sizes for bulk orders. Just let us know your needs before shipping.
Standard lead time is 5–7 business days after payment confirmation. Expedited shipping is available if you need it sooner.
