FAQ

Questions, answered.

Yes. Every lot is independently assayed for purity by reverse-phase HPLC and confirmed for identity by mass spectrometry before it is listed. The certificate is archived against a unique lot ID and published in the COA lookup.

Use the COA lookup to search by compound or lot number. The matching certificate also lives in your account after purchase.

Products are supplied as a lyophilized powder, shelf-stable and sealed against light and moisture — no cold chain required for shipping. For long-term storage, keep lyophilized material at -20°C and protected from light. Storage guidance is listed on each product page.

In-stock orders are dispatched the same or next business day with tracking. Expedited options are available at checkout. See Shipping for details.

Yes. Orders ship in plain, unbranded, tamper-evident packaging. Nothing on the outside identifies the contents.
