What is a COA?
A Certificate of Analysis is a third-party laboratory report documenting:
- Identity confirmation (compound matches stated specification)
- Purity by HPLC (high-performance liquid chromatography) — typically > 98% for peptides
- Water content, residual solvents, heavy metals, and microbial contamination tests as applicable
- Test date and analyst signature
COAs are provided directly by our suppliers' independent third-party laboratories. Amino Development Group LLC re-verifies COA integrity but does not modify or re-test products in-house.
For Research Use Only. COAs document chemical purity for laboratory research purposes only and are not certifications of safety or fitness for human or veterinary use.
