Optiq Health Labs provides independent peptide net content testing using advanced LC-MS technology to measure active peptide content and verify label claims. Our laboratory delivers accurate analytical results that support product quality, consistency, and confidence.
Net content testing helps determine whether a peptide contains the amount of active ingredient it claims to contain. In today’s rapidly growing peptide market, label claims are not always independently verified, making net content testing an important tool for confirming product quality and consistency.
At Optiq Health Labs, we perform advanced analytical testing to verify peptide identity and quantify active peptide content, helping ensure products match their stated specifications. Net content testing provides valuable insight into whether a sample delivers the expected amount of peptide, giving manufacturers, researchers, and consumers greater confidence in the products they use.
A peptide may be correctly identified and highly pure, yet still contain less active material than advertised. Net content testing helps verify label accuracy, supports quality control, and promotes transparency through independent third-party analysis. In an industry with limited oversight, verifying potency is one of the most effective ways to ensure you are getting exactly what you paid for. We utilize an LC Mass spec to ensure we get the most accurate results.
How much does LC-MS peptide purity testing cost and how long does it take?
Purity testing is one of the most important analytical procedures used in peptide quality assessment. Even when a product is labeled as a specific peptide, manufacturing processes, handling conditions, storage environments, and degradation over time can introduce additional compounds that are not part of the intended material.
At Optiq Health Labs, we use advanced Liquid Chromatography–Mass Spectrometry (LC-MS) methods to evaluate peptide purity with a high level of precision and consistency. LC-MS technology separates the individual components within a sample while simultaneously confirming molecular identity through mass analysis.
This process allows our laboratory to:
Liquid Chromatography (LC) separates the individual compounds within a sample. Mass Spectrometry (MS) then identifies and analyzes those compounds by measuring their molecular mass and structure.
We utilize Liquid Chromatography–Mass Spectrometry to separate compounds within the sample and identify the molecular mass of detectable components.
Testing helps determine the relative percentage of the intended peptide compared to other detectable substances present in the sample.
Mass spectrometry helps verify that the detected primary compound aligns with the expected molecular profile of the target peptide.
Analysis may reveal manufacturing impurities, degradation compounds, residual byproducts, or other detectable materials within the sample.

Net content testing measures how much active peptide is present within a sample and compares the result against the product's labeled claim.
No. Purity measures how much of the sample is the intended peptide compared to impurities, while potency measures the amount of active peptide material present.
Net content testing helps verify label accuracy and confirms whether a product contains the amount of peptide advertised. This helps ensure dosing is done properly and safely.
Yes. A peptide may show high purity while still containing less active peptide material than expected.
