Signal Over Noise
At Vanguard Peptides, quality starts with clear standards and documentation. We use U.S.-based third-party laboratories to evaluate our products and provide information that helps researchers assess their suitability for laboratory work.
Our commitment is straightforward: communicate what was tested, make results understandable, and represent those results accurately.
What We Test
Our third-party testing includes four areas:
Identity
Evaluates whether the tested material matches the expected compound.
Purity
Measures the proportion of the target compound relative to other components detected by the analytical method. Purity is distinct from the amount of compound present.
Quantity
Measures the amount of the target compound in the tested sample, allowing comparison with its labeled quantity.
Sterility
Evaluates the tested samples for microbial growth under the conditions of the sterility test.
Independent Verification
Third-party testing provides an assessment separate from supplier documentation. We review these results alongside product and lot information to support our quality process.
We describe testing according to the scope of the actual report. A result for one measurement does not establish results for another.
Understanding the Results
A testing report documents findings for the sample submitted using the methods identified. It does not mean that every vial was individually tested.
Sterility testing and endotoxin testing are separate assessments. Our testing does not include endotoxins, and sterility results do not establish their absence.
Laboratory results characterize the tested material; they do not establish safety or suitability for human or animal use.
Testing Documentation
When reviewing a report, match its product name and lot or batch identifier to the corresponding product. The report should be read alongside its methods, results, and any stated limitations.
