Straight from the manufacturer, tested every lot.
We source directly from the synthesis facility and hold stock in US warehouses. Every lot is tested before it ships, and every report is public.

We buy straight from the synthesis facility, with no brokers in between. That is how box pricing stays below most retail per-vial prices.
Tested every lot
Each production lot is checked for purity by HPLC and identity by mass spectrometry, and the report is published before it ships.
Cold-stored in the US
Inventory is held refrigerated or frozen in US warehouses and ships domestically, with no customs delays.
Sealed and traceable
Every box carries a lot number that matches its certificate of analysis in our library.

Consistent packs
One strength per box, 10 vials per box, so stock is easy to count, list and reorder.
Volume ready
Tier pricing to 20% off base, and quotes for bulk or recurring volume on request.
