We've seen the RFQ come through, and the 99.5% purity is what we run —it's tested by Janoshik, and you'll get the COA with the shipment, usually within 24 hours of dispatch.

The powder comes lyophilized, white, and it's solid at room temperture; we've found that storing it in a cool, dry place keeps it stable for 20 days or so after reconstitution, but most buyers go with teh 10mg vials for easier handling.


MOQ is one box of ten vials, and we can do 2mg, 5mg, or even 15mg per vial depending on your protocol—custom packging with your logo is no problem, though label design adds about 3 days to lead time (check with us first).

It's better than reagent grade for this specific work because the tighter tolerance—roughly ±0.3%—means you don't see kind of drift you get from cheaper suppliers, though it's not suited for anything beyond research use, just to be clear.

Anyway, we're ISO9001 certified, so the production standard is pretty much locked in, and we usually have stock on the 5mg and 10mg sizes, but confirm lead time if you need a custom batch—sometimes it's 15 days or so.
Our MOQ is 1 box containing 10 vials. We don't split boxes, but you can mix different dosage sizes in one order if you need a variety.
For standard orders with logo or packaging customization, lead time is usually 5-7 business days after payment confirmation. We'll keep you updated on any delays.
Yes, every batch comes with a Janoshik test certificate showing the ≥99.5% purity. We can share it before shipping if you need to review it.
Store it in a cool, dry place away from direct sunlight. For extended storage, keeping it in the fridge at 2-8°C in its sealed vial is best, but avoid freezing.
Absolutely, we offer custom dosages beyond the standard 2mg to 20mg range. Just let us know the exact mg per vial you need, and we'll adjust the production.
