Batch Identification Policy

All vial labels have a Batch Id that can be reconciled against the various COAs for Purity/Assay, Endotoxin, Heavy Metals, or Sterility testing at https://peptide.partners/pages/peptide-overviews

Sample Authentication Guidance

Our 3mL vials have a 1.25" x 0.75" white, BOPP label. At the top of the label is the full logo with the 'P Vial' symbol on the left, followed Peptide Partners, and underneath it says "CONNECTING THE GLOBAL RESEARCH COMMUNITY." Underneath the logo is a line identifying the molecule and weight. Underneath that is the word 'Batch' followed by an identification code. At the bottom of the label it reads "Research Use Only"

Corrections

10 Oct 2025:: Peptide Partners have elected to have all their samples tested against the label claim. The "batch claim" from COAs is not taken into account. Some test scores have been updated accordingly.
