Independent Third-Party Testing
Every batch of peptides sold by Ohana Peptides is independently tested at a US-based ISO 17025 accredited laboratory before being listed for sale. We never rely on manufacturer-provided certificates alone.
Testing Methods
- Purity Analysis: Reversed-phase high-performance liquid chromatography (RP-HPLC) with C18 column and 220nm UV detection
- Identity Confirmation: Electrospray ionization mass spectrometry (ESI-MS) to verify molecular weight matches the target compound
- Minimum Purity Threshold: 99%+ by area under curve on HPLC chromatogram
Certificate of Analysis (COA)
Every order includes a Certificate of Analysis documenting batch number, testing date, purity percentage, observed molecular weight, and the name of the testing laboratory. Batch numbers can be verified at ohanapeptides.com/coa.
Storage and Handling
All peptides are stored at 2-8 degrees Celsius in a desiccated environment, protected from light. Shipping uses cold-chain packaging with gel ice packs in insulated containers from our California facility.
