Every batch of Loyal Labs products is independently tested. Look up your specific lot number to see exactly what's in your vial.
Search by lot number or browse by product to view test results.
Not sure what all those test results mean? We'll break down everything in plain language so you can make informed decisions about your pet's health.
A Certificate of Analysis (COA) is an official document from an independent laboratory that verifies a product's identity, purity, and safety. Think of it as a detailed report card for each batch of product we manufacture. Every COA includes multiple tests that answer critical questions: Is this actually the compound we claim? How pure is it? Is it safe for injection? Is it free from harmful contaminants? At Loyal Labs, we provide COAs for every lot we produce — not just a sample from months ago, but the actual batch your product comes from. This transparency lets you verify exactly what you're giving your pet.
Mass spectrometry confirms the molecular weight matches the intended compound
HPLC analysis measures the exact percentage of pure peptide vs impurities
Endotoxin and sterility tests ensure the product is safe for injection
Each lot number links to manufacturing and expiration dates
Anyone can claim their product is pure. A COA from an independent lab proves it. We don't ask you to trust us — we show you the data.
Each manufacturing batch is different. We test every lot and provide the specific COA for the product in your hands, not a generic template.
Impure or contaminated products can cause adverse reactions. COA testing catches problems before products ever reach you.
With full test results, you and your veterinarian can make informed decisions about what goes into your pet's protocol.

Not all COAs are created equal. Here's what should raise concerns:
The COA should match the lot number on your product. Generic COAs don't prove anything about your specific batch.
A complete COA includes HPLC, mass spec, endotoxin, and sterility at minimum. Missing tests mean unknown risks.
Reputable companies use independent third-party labs. In-house testing creates conflicts of interest.
'Passes' or 'Acceptable' without specific numbers hide poor results. Demand exact values.
COAs should be recent and match manufacturing dates. Tests from years ago don't reflect current quality.
Look for ISO 17025 accreditation or GLP compliance. Unaccredited labs may lack proper standards.
We believe in complete transparency. If you have any questions about our testing procedures or need help interpreting your COA, our team is here to help.
