- 99% purity target. We reject lots that do not meet our purity threshold, so your experiments aren't held back by your reagents.
- Cold-chain handling. Lyophilized vials are stored at -20 °C and shipped in insulated mailers with cold packs.
- Lot & batch tracking. Every vial ships with a lot identifier so you can request the matching COA at any time.
- Discreet, tracked US shipping. Plain unbranded outer packaging, sealed for privacy, 2–5 business day delivery.
