Every batch is tested in-house by HPLC and independently re-verified by a third-party laboratory. We publish the Certificate of Analysis for each lot before the product ships.
Each Certificate of Analysis includes the compound's identity, HPLC purity percentage, mass-spec verification, lot number, manufacture date, and a sign-off from the testing laboratory.
Compounds ship lyophilized in temperature-controlled, insulated packaging with cold packs. Once received, store at the temperature specified on the COA — typically refrigerated or frozen.
Yes. Every lot we have ever shipped is searchable in the public COA library by batch ID. Reach out if you need a hand locating a specific record.
If a batch does not meet the purity threshold listed on the COA, we replace it — no questions. Independent re-verification is welcome and reimbursable.
Domestic US shipping is supported by default. International availability depends on the destination country's regulations — contact us for a routing assessment before placing an order.
Orders placed before the same-day cutoff ship the same business day. Most US destinations arrive within 1–3 business days, all temperature-controlled end-to-end.
All compounds are synthesized in cGMP-aligned facilities in the United States, then third-party tested before they are released for sale.
