We understand the market
Overseas manufacturers, domestic resellers, private groups, and changing storefronts can make source and batch history difficult to follow.
Independent Analytical Chemistry
Precision analysis.
Trusted results.
Research compounds can move through manufacturers, exporters, resellers, and multiple storefronts before reaching your mailbox. Labels and certificates tell only part of the story. Zavco Labs provides independent U.S.-based LC/MS and HPLC testing to help determine what is actually in the vial you received.
Verify the vial.
Not just the claim.
Identity and Purity
LC/MS and HPLC analysis to assess whether the expected compound is present and evaluate chromatographic purity.
Mass per Vial
Quantitative analysis to compare measured peptide content with the label claim and identify meaningful underfill or overfill.
Batch Comparison
Compare submitted samples to help identify meaningful differences between orders, lots, or vendors.
Why Zavco Exists
Built around the questions the community already asks.
Zavco Labs was created for people who want evidence from the vial in hand, not another marketing claim. Our role is simple. Measure the sample, explain the result, and be clear about what the data can support.
Independent means independent
We do not manufacture or sell research peptides. The result does not affect a product sale, vendor ranking, or commission.
We test your vial
A supplier COA may represent another sample or an earlier lot. Zavco analyzes the material that you submit and ties the report to the information received with it.
Clear answers, practical timing
Identity, purity, mass, and batch comparison are reported in direct language without unnecessary jargon or inflated claims.
Questions We Help Answer
What do you actually need to know?
The goal is not to create another certificate. The goal is to reduce uncertainty about the specific material you received.
Is this the compound shown on the label?
LC/MS provides mass based evidence to assess whether the expected research compound is present.
How clean is the chromatographic profile?
HPLC evaluates the main peak and measurable secondary components. Purity does not establish sterility or prove that every material in the vial is peptide.
Does the vial contain the labeled amount?
Quantitative testing can identify meaningful underfill or overfill and compare measured content with the stated milligrams.
Does this result belong to my batch?
Testing the submitted vial provides a direct analytical record linked to the sample and batch details provided by the customer.
Sample Instrument Output
Analytical data, not marketing graphics.
These sample outputs show the type of chromatographic and mass spectral data generated during HPLC and LC/MS analysis. Final interpretation depends on the method, reference material, sample preparation, and review of the complete data set.
Chromatographic Output
Sample HPLC chromatogram
The chromatogram displays detector response over retention time and shows the separation profile produced by the analytical method.
Mass Spectral Output
Sample MSD mass spectrum
The mass spectrum displays observed ions by mass to charge ratio and supports compound identity when reviewed against the expected molecular species.
Sample instrument outputs are shown for illustration. They are not presented as a certificate of analysis or as results for a specific customer sample.
We report what the data supports. Nothing more. Nothing less.
Know what arrived and whether it matches what was purchased.
Research peptides may pass through overseas manufacturers, brokers, domestic resellers, and multiple storefronts before reaching the buyer. A polished label, QR code, or vendor supplied COA does not prove that the vial in hand came from the tested batch. It also does not prove the compound, purity, or stated milligrams.
Zavco Labs provides an independent analytical checkpoint for community members, researchers, and vendors seeking verification of a specific vial or batch. Results are generated from the material actually submitted.
Identity, purity, and mass testing do not establish sterility, endotoxin level, or suitability for human use. We explain the method, the result, and the limitations in direct language.
