At C&D Peptides, transparency and trust are at the core of what we do. Every product we supply undergoes independent third-party testing to confirm its identity, purity, and consistency. These Certificates of Analysis (COAs)are your assurance that what you see on the label is exactly what you receive.
Why COAs Matter
✅ Independent verification – All tests are carried out by accredited third-party labs.
✅ Purity guaranteed – Each report shows exact purity percentages so you can trust the integrity of our peptides.
✅ Batch-specific results – We provide COAs linked directly to the product you purchase.
✅ Full transparency – No hidden data, no vague claims — just clear, verifiable results.
How to Verify
Each COA includes a unique verification key and QR code that can be cross-checked directly with the testing laboratory. This means you can independently confirm the validity of every certificate we publish.
Our Commitment
We believe researchers deserve the highest standards of confidence in their work. By publishing our COAs openly, we hold ourselves accountable to the same strict standards we expect from our industry.
