A 99% purity threshold is what we target, and we stick to that figure because anything less introduces variability in results that most researchers can’t afford to chase down—basically, it’s the difference between trusting your data and spending weeks troubleshooting.
Each lot gets run through HPLC with a COA issued, and we keep raw data on file for two years if you need to dig into it later.

You’re looking at a that reconstitutes cleanly, no cloudiness or residue—this matters more than most buyers realize when they’re dilution-plotting at 5mg per vial.

We pack 10 vials to a box in 5mg, 10mg, or 20mg sizes, and (usually) our company have shelf stock of all three. MOQ is typically one box, so 10 vials minimum, but if you need 50 boxes give us a heads-up on lead time since it can stretch to 20 days or so.
Teh 2-year shelf life is real under cool, dry storage—but if you’re receiving a batch that’s 18 months old we’ll apply a 30-day retest policy before you even have to ask. Just a concrete detail we handle.
We can start with as low as 10 vials per order, but for bulk supply we usually ask for a minimum of 100 vials. Contact us for exact MOQ on larger custom batches.
Yes, every batch comes with a COA showing HPLC analysis and purity results. Just request it with your order and we'll include it in the shipment.
Absolutely, we can tailor the fill amount per vial to your specs, as long as it's within our production capabilities. Let us know the exact mg per vial and we'll quote you.
For standard bulk orders, lead time is usually 7-14 business days after payment and specification confirmation. Rush orders may be possible for an extra fee.
Keep it in a cool, dry place away from direct sunlight and moisture, ideally at 2-8°C. If stored properly in the sealed vial, you'll get the full 2-year shelf life.
