We’ve got the COA form our in-house HPLC run showing >99% purity, and our company can also arrange a third-party retest at your cost if you want an independent verification before committing to a full batch.
Batch consistency is something we track closely—every lyophilized lot gets a stability check at 0, 6, and 12 months, and we’ll share the raw data alongside the certificte of analysis (COA) and the GMP/ISO 9001 certs.

The retest policy is straightforward: if you find a discrepancy within 30 days of receipt, we’ll replace the batch or issue a credit, but we usually have stock on hand so turnaround is about 2 weeks or so.
Most buyers go with the 10mg or 15mg vials for dose-response work, but we also carry 5mg, 12mg, 20mg, 30mg, 40mg, and 60mg—just confirm teh MOQ if you need a mix of sizes.

It’s not suited for anything beyond research use, obviously, and lyophilized powder needs a cool, dry place—don’t store it above 25°C or it’ll degrade faster than the 2-year shelf life suggests.
Anyway, if you’re ready to order, we ship 10, and we can include the SDS and TDS in the package—just let us know the quantty and preferred carrier.
It means you're getting a discounted price when ordering in bulk quantities—usually 10 boxes or more. The coupon applies per box, so the more you order, the more you save per vial.
Yes, we do. Each batch comes with a CoA showing the >99% purity, and we can also share the GMP and ISO 9001 certs on request.
The MOQ is 10 vials per box, but you can mix different specs like 5mg and 10mg in one bulk order. Just let us know your preferred combination.
Keep them in a cool, dry place away from direct sunlight and moisture. After reconstitution, use immediately and don't freeze the liquid form.
We usually pack 10 vials per box, but if you need a custom package for research, we can arrange single vials or smaller sets—just talk to our sales team first.
