All Bluewell peptides are independently HPLC-tested to 99.1%+ purity. Select a product below to view the latest COA.
Batch specific: COAs are generated per batch, so values like purity % can vary slightly from one batch to the next. We always publish our most recent COAs. If you need a previous batch report or extended data, contact us.
COA FAQs
Why might a COA I saw elsewhere look different?
COAs are batch-specific. Purity and other values can vary slightly from batch to batch.
Where do I find my batch number?
It’s printed on your vial label. Match it to the COA header for verification.
What purity are Bluewell peptides?
All Bluewell peptides are independently HPLC-tested to 99.1%+ purity. Each COA shows the exact purity for that specific batch.
What is HPLC testing?
HPLC stands for High-Performance Liquid Chromatography. It is a gold-standard analytical method used to confirm the purity and composition of peptides. Every Bluewell peptide is independently HPLC-tested to ensure it meets our minimum standard of 99.1%+ purity.
How are Bluewell peptides tested?
Every batch of Bluewell peptides is tested by accredited independent laboratories before release. We never rely solely on manufacturer documentation. Each product undergoes HPLC analysis to confirm both purity and identity, with a minimum standard of 99.1%+. The results are documented in a full Certificate of Analysis (COA).
Can I download or print the COA?
Yes. You can save the image directly, or on the product page of each peptide you will find a downloadable resource inside the description. If you need a formal PDF copy for your records, please contact us.
Can I request historical COAs or extended lab data?
Absolutely. We keep previous batch reports and can supply extended data on request. Please contact us with your product and batch number.
