At Stratford Peptides, quality and transparency are central to everything we do. Every peptide batch is tested to ensure that what you receive is exactly as described.

Independent Laboratory Testing

Each batch is sent to independent, certified laboratories for verification. These labs perform advanced analysis such as High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to confirm purity, identity, and concentration.

Certificates of Analysis (CoAs)

We maintain a Certificate of Analysis (CoA) for every batch. These documents provide the official lab results and are available to customers upon request.

Store Credit for Independent Testing

We are confident in our quality and encourage customers to arrange their own third-party testing if they wish. If testing is carried out by a reputable laboratory, Stratford Peptides may provide store credit equal to the cost of the test.

Process:

1. Contact us before arranging the test.
   
2. Share the lab report and invoice once testing is complete.
   
3. We will guide you through the process and apply your credit.
   

Why This Matters

This policy gives you complete peace of mind. You can confirm our quality independently, or if an issue is found, we make it right. To date, our peptides consistently meet or exceed stated purity levels and we stand firmly behind every vial.
