Every product on this site is supplied as a laboratory reagent for in-vitro research. It is not a drug, supplement, food or cosmetic, and it is not for human or veterinary use. Ordering requires confirming that you are 21 or older, that you are a qualified researcher, and that you accept the terms of sale.

Each production lot is sampled and sent to an independent US laboratory for purity by RP-HPLC at 220 nm and identity by ESI-MS. The lot number printed on the vial resolves to that certificate on the certificates page. Our specification is a minimum of 99 % purity; a lot below specification is not released.

Synthesis and lyophilization take place in a US facility operating under cGMP quality systems. Fill, cap and label are done in-house.

Orders placed before 14:00 Eastern on a business day are dispatched the same day. Later orders go the next business day. Everything ships in plain, unbranded packaging with a lot-numbered packing slip, and tracking is emailed when the label prints.

Lyophilized vials are stable at ambient temperature in transit. On receipt, store sealed vials at −20 °C, protected from light. A storage card is included in every order.
