We test every batch ourselves with HPLC and mass spec before it leaves—purity consistently runs above 99.9%, but you should still check teh COA we send with each shipment.

Basically, testing protocol covers three rounds: raw materail verification at intake, in-process checks during filling, and a final release test on the finished vial. Each batch gets its own unique lot number, and we keep retained samples for 12 months in case you need a retest later. The retest policy is pretty straightforward—if you get a result outside spec within 30 days of receipt, we'll replace it or refund, no questions asked. We usually have stock on the 10mg vials, but confirm lead time if you're ordering more than 50 units or so.

Batch-to-batch consistency is something we actually track—variation in purity between lots is typically less than 0.1%, and we've seen tighter tolerance than most supliers on the molecular weight confirmation. That matters when you're running dose-response studies and don't want surprises.

One thing some buyers don't think to ask: we store everything at 2-8°C in light-protected packaging from the moment it's filled, and we use temperture loggers on every outbound shipment. So even if your order sits in transit for 20 days or so, it stays stable.

It's not suited for anything beyond research use—don't try to use it as a finished pharmaceutical product, because we don't test for that. Anyway, the MOQ is 10 vials, and our company can do mixed lots if you need different amounts.
The MOQ is 10 vials. If you need a custom quantity, let me know and we can discuss it from there.
Typically, we can ship within 3-5 business days after order confirmation, depending on stock availability. For larger orders, we'll give you a more precise timeline.
Yes, we include a COA with every batch that shows the actual purity and other specs. Just request it when you place your order.
Keep them refrigerated at 2-8°C and protect from light. Do not freeze, and use within the recommended period after reconstitution.
We currently supply only 10mg/vial as standard. However, we can discuss custom packaging for large-volume orders. Contact us with your requirements.
