3RD PARTY TESTED
Calivo Labs — Third-Party Testing
Why Third-Party Testing Matters
In the peptide research market, a label on a vial is not proof of what's inside it. Many suppliers recycle outdated Certificates of Analysis, test only a single "showcase" batch, or skip endotoxin screening entirely. The result is a market where the researcher bears the risk.
Calivo Labs operates differently. Every production lot we release undergoes independent third-party verification by a laboratory that has no financial relationship with our company. We do not test our own products and report the results. We send them out — and publish what comes back.
Who Tests Our Products
Our third-party verification is performed by Frontage Laboratories, Inc., an FDA-inspected Contract Research Organization (CRO) headquartered in Exton, Pennsylvania. Frontage operates under GLP-compliant (Good Laboratory Practice) conditions and serves the pharmaceutical, biotech, and chemical industries.

Frontage was selected specifically because they are not a peptide supplier, they have no commercial interest in our products, and their analytical results carry the credibility of an organization that serves FDA-regulated clients. When Frontage signs a test report, it is not a marketing document — it is an independent analytical finding.
What We Test — Every Lot
HPLC Purity Analysis: High-Performance Liquid Chromatography separates the target peptide from impurities, truncated sequences, and synthesis byproducts. Calivo Labs requires a minimum 98% purity on every lot. Our current production lot (Lot CL-BT-20260208-01) tested at 99.1%.
Mass Spectrometry (MS) Identity Confirmation: Mass Spectrometry measures the exact molecular weight of the compound to confirm that the vial contains what the label says it contains. BPC-157 theoretical molecular weight: 1419.55 Da. TB-500 (Thymosin Beta-4) theoretical molecular weight: 4963.51 Da. Both compounds confirmed within ±1.0 Da tolerance on the current lot.
Endotoxin Testing (LAL): Limulus Amebocyte Lysate testing detects bacterial endotoxins (lipopolysaccharides) that can contaminate peptide synthesis. Calivo Labs specification: ≤0.5 EU/mg. Current lot conforms.
Microbial Testing: Total Aerobic Count and Yeast & Molds testing confirms that the lyophilized product meets microbial cleanliness standards. Specification: ≤100 CFU/g for both categories. Current lot conforms.
Net Peptide Content Verification: We verify the actual peptide mass in every vial — not just the total powder weight. Our current lot's labeled 10mg blend was measured at 11.7mg of net peptide content. You receive more than what's on the label, not less.
What Makes This Different
Batch-specific, not generic. Every COA we publish corresponds to the exact lot number in your package. We do not recycle test reports from previous batches.
Independent, not in-house. Frontage Laboratories has no financial stake in whether our products pass or fail. Their reputation depends on analytical accuracy, not on our sales.
Published, not hidden. Our full HPLC chromatograms, Mass Spectrometry spectra, and Certificates of Analysis are available on every product page — not behind a login wall, not "available upon request."
Overfilled, not underfilled. Most suppliers deliver less peptide content than the label states. Our vials are independently verified to exceed labeled amounts.
Verify It Yourself
Every Calivo Labs product page includes the full Certificate of Analysis, HPLC Analysis Report, and Mass Spectrometry Report for the current production lot. The documentation is embedded directly on the page under the COA / HPLC / MS tab. Download it. Read it. Compare it to any other supplier's documentation. That's exactly why we put it there.
