Peptide Caviar
Quality Assurance
At Peptide Caviar, transparency and trust are at the heart of everything we do.
Every batch
third-party verified
We third party test every product in an ISO/IEC accredited laboratory, certified by the board ecology, for endotoxins, heavy metals, purity and content.
At Peptide Caviar, quality is our top priority. Every product we offer is rigorously tested using the most advanced technology available in the United States. We work exclusively with leading U.S. laboratories to verify purity, content, endotoxins, and heavy metals. Choosing a lab-tested, third-party verified peptide supplement is essential for ensuring both purity and safety, and at Peptide Caviar, we take that responsibility seriously.

Browse COA LibraryFrequently Asked Questions
Yes. Each peptide undergoes multi-panel laboratory testing to assess purity and content, along with endotoxin screening, heavy metal analysis, and sterility testing.
Our peptides typically test at over 99% purity. Each batch is verified using laboratory methods such as HPLC, with supporting documentation available in the COA library when applicable.
Peptides are most commonly produced using solid-phase peptide synthesis (SPPS), a standard method where amino acids are added step-by-step in a controlled sequence. After synthesis, the peptide is cleaved, purified (often via HPLC), and verified using analytical testing such as mass spectrometry to confirm identity and purity.
