CERTIFICATES OF ANALYSIS
Every Nexera product is backed by a third-party Certificate of Analysis (COA). COAs confirm the identity, purity, and potency of each compound through independent laboratory testing.
Why COAs Matter
In peptide and research compound procurement, purity is everything. A COA from an accredited third-party lab verifies that what’s on the label is what’s in the vial — no fillers, no inconsistencies. We publish COAs as part of our commitment to full transparency.
How to Request a COA
COAs are available on request for all products. To obtain the COA for a specific product:
- Email us at the address on our Contact page
- Include the product name and batch/lot number (found on your packaging)
We aim to respond with the corresponding COA within one business day.
Testing Standards
- Purity: ≥98% (HPLC verified)
- Identity: Confirmed by Mass Spectrometry (MS)
- Sterility: Tested where applicable
- Endotoxin: Tested where applicable (LAL method)
Nexera products are intended for research purposes only and are not approved for human or veterinary use.
