How to verify a vial
We publish reports per lot, not per product. That means the document you read describes the exact batch in your hands, including the date it was tested and the lab that tested it.
Read our laboratory standardsIt is printed on the vial label and on your packing slip.
Search by compound, size or lot. Each entry opens the original PDF from the testing laboratory.
Purity by HPLC, mass by LC-MS against the expected molecular weight, and net peptide content.

Why researchers order here
Lots are tested by third-party analytical labs, never in-house. Reports are published unedited.
Orders before 2 pm ET leave the same business day in insulated, discreet packaging with cold packs where needed.
Lyophilized stock is held at −20 °C from receipt to dispatch, with temperature logs available on request.
Email or call during U.S. business hours. Shipping issues are resolved with a replacement, not a form.
Add any peptide to your cart and we add a second vial of the same compound and size at no charge. Every two vials of a product count as one paid and one free, so 2 vials cost the single-vial price, 4 vials cost double, and so on. The free vial is applied automatically in the cart, and the saving is shown on its own line.
Bacteriostatic water and the reconstitution kit. Everything else in the catalog, including the blended stack vials, qualifies.
No. BOGO is already the best price on every vial, so promo codes do not stack with it.
Open the COA Library and search by compound or by the lot number printed on your vial label. Each entry links to the original laboratory PDF. Product pages also link straight to the report for the lot currently shipping.
Purity (HPLC) is the percentage of the sample that is the target peptide. Identity (LC-MS) confirms the measured mass matches the expected molecular weight. Net content is the actual peptide mass in the vial. Endotoxin, where tested, is reported in EU per mg.
Shipping within the United States is free on every order. Orders placed before 2 pm Eastern on a business day ship the same day; most deliveries arrive in 2 to 4 business days. Tracking is emailed as soon as the label is scanned.
