THIRD PARTY LAB TEST RESULTS

Independent Laboratory Verification

At Peptide Lab Global, product quality is validated through independent third-party laboratory testing. Selected research peptides are routinely submitted to recognized analytical laboratories such as Janoshik Analytical for verification of purity, identity, and safety markers.

These external laboratories conduct analytical testing using validated scientific methods. Testing commonly includes high performance liquid chromatography (HPLC) for purity determination, mass spectrometry for molecular confirmation, and when applicable, screening for heavy metals and endotoxin levels.

All available Certificates of Analysis (CoAs) are provided in PDF format for transparency and documentation purposes.

What Our Certificates Include

Each Certificate of Analysis contains detailed laboratory findings, including:

  • Product name and batch reference
  • Date of analysis
  • Analytical methods performed
  • Measured purity percentage
  • Chromatography data
  • Molecular mass confirmation
  • Heavy metal screening results (when tested)
  • Endotoxin results (when tested)

For Janoshik-tested products, verification can typically be confirmed through the laboratory's official validation system where available.

We continue to expand the number of products undergoing independent testing and periodically re-test peptides to maintain consistent quality standards.

Ongoing Quality Commitment

Our approach emphasizes transparency and analytical validation. While not every batch is tested simultaneously, we prioritize high purity products and maintain an active schedule of independent verification.

If specific batch documentation is required before purchase, our support team can assist upon request.

Independent Customer Testing

We welcome independent verification from researchers. Customers who submit official third-party testing documentation for our products may qualify for store credit reimbursement covering the cost of laboratory analysis, subject to review.

To request review, please provide:

  • Laboratory invoice
  • Official test report
  • Batch number tested

All submissions are evaluated by our quality team.
