Peptide Lab Tests

14,430 certificates of analysis are on file, from 380 shops and 29 labs. The latest was tested on .

These are certificates shops have chosen to publish, verified for authenticity before listing. Because shops decide which COAs to make public, the set reflects the batches they published rather than every production batch — a selection bias we state openly. What shop COAs show →

Shop withheld — during active brand-owner enforcement we do not attribute test results to individual shops. Lab, date, lot and results are shown in full. Measured amount in amber when it is under 90% or over 130% of the label. Records without a lot number link as View →. Community marks a certificate a member sent in, not the shop.

How to read a record

what each column shows, and what it doesn't
  1. Purity (HPLC). The main compound's share of what the lab's HPLC run detected. It doesn't show how much is in the vial or prove which molecule it is. How to read HPLC and mass-spec results
  2. Measured vs label. The amount the lab measured against the amount on the label. A vial can be pure and still short. Why 10 mg isn't 10 mg
  3. Endotoxin. Shown when the certificate reports it, in the lab's own units — EU/mg, EU/mL or per vial — which don't convert without the vial's contents. A dash means no result on the certificate, not a pass. Sterility and content uniformity show on the test page when the certificate has them; a failed one adds a red tag to the row. Endotoxin testing and LAL interpretation
  4. Lot and ✓. The lot printed on the certificate. ✓ means a Peptigrity staff member found the same report on the lab's own public portal. Red flags in a certificate of analysis · Testing labs we track
  5. Who sent it. 14,427 of the 14,430 certificates were published by the shops themselves and 3 by members. Shops choose what to publish, so read every figure with that in mind. Supplier-provided marks a certificate the shop's supplier had done; it's listed, not counted. What shop COAs show
  6. What no record shows. Identity isn't a column: whether mass spectrometry confirmed the molecule is on the certificate itself, when the lab ran it. No certificate says anything about dosing, efficacy or safety.
