Every compound listed has a released lot behind it and a published certificate for that lot. For laboratory research use only. Not for human consumption.
Chain of custody
This strip describes how every lot is handled. The measured figures for the lot you receive are read off its own certificate on the product page, never from a house average and never from a historic batch.
For laboratory research use only. Not for human consumption.

Purchase is restricted to buyers aged 21 or over, or 18 or over where 18 is the age of majority in the buyer jurisdiction, and the affirmation is recorded per device on entry.
Purchasers are responsible for compliance with every law applicable where they take delivery, including import, export and controlled-substance rules. We do not ship to restricted destinations and we cancel and refund orders placed from them. Title passes at dispatch from Madison, Wisconsin.

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.
