Documentation
Every lot carries a dated certificate of analysis, published before the lot is listed. No email request, no account and no purchase is required to read one.
Open the lot archivePurity and identity
HPLC-UV purity with the measured figure printed on the certificate, plus mass-spectrometry identity confirmation. Where an endotoxin, heavy-metal or microbial panel was run, that report is published alongside it.
What each report coversCold chain
Lots are held at minus 20 C with continuous logging and dispatched gel-packed in insulated cartons. The temperature record for your parcel travels with it and is reproduced on request.
How a parcel is handledPayment
Card, ACH bank transfer and cryptocurrency. Bank transfer and cryptocurrency payments are not reversible once settled, which changes what a return can be. Read the returns policy before choosing one.
Returns and refundsJurisdiction
We ship within the United States and to a published list of international destinations. Buyers outside that list are not accepted, and buyer-side import compliance remains the buyer responsibility in all cases.
