Maple Maple Research Labs provides independent third-party Certificates of Analysis (COA) from Janoshik Analytical, an independent third-party testing laboratory based in Prague, Czech Republic. Each COA includes HPLC purity analysis results and a unique verification key that can be independently confirmed on the Janoshik website.
This page serves as a centralized index of all current COA documentation across our product catalog. Researchers, institutions, and procurement departments can use this page to verify the testing status and purity data for any compound before placing an order.
How Our Testing Process Works
Our quality verification process includes the following steps:
- Sample submission: A sample from each manufactured batch is sent to Janoshik Analytical for independent testing.
- HPLC analysis: High-Performance Liquid Chromatography (HPLC) determines the exact purity percentage of the compound.
- COA generation: Janoshik issues a Certificate of Analysis with the purity result, batch identifier, and a unique verification key.
- Public verification: The verification key can be entered at janoshik.com to independently confirm the test results.
- Product page linkage: The COA document is linked directly on the corresponding product page as COA verification is completed.
Products with verified COAs are clearly indicated on their product pages. Products with pending COA verification are noted in the status table above.

Understanding HPLC Purity Results
High-Performance Liquid Chromatography (HPLC) is the gold standard for peptide purity analysis. The purity percentage indicates the proportion of the target compound relative to total detected substances in the sample. Research-grade peptides typically achieve purity levels above 98%. Maple Research Labs maintains a minimum threshold of 98% HPLC-verified purity across all products.
The HPLC method separates individual components of a sample based on their interaction with a stationary phase and mobile phase. Each component produces a distinct peak on the chromatogram, and the relative area of the target compound peak determines the purity percentage. According to analytical chemistry standards, HPLC achieves accuracy levels exceeding 99.5% for peptide quantification.
Why Independent Third-Party Testing Matters
In-house testing creates an inherent conflict of interest: the company manufacturing the product is also the one certifying its quality. Independent third-party testing eliminates this conflict entirely. Janoshik Analytical has no financial relationship with Maple Research Labs beyond the testing fee. Their results are independently verifiable through public verification keys, creating a chain of trust that does not rely on the supplier’s word alone.
A 2023 analysis of the research peptide market found that fewer than 15% of suppliers provide independently verified batch-specific COAs. Among those that do, fewer than half offer public verification of the testing results. Maple Research Labs is among a small number of Canadian suppliers that meet both criteria.
Frequently Asked Questions
How do I verify a COA from Maple Research Labs?
Each COA includes a unique verification key issued by Janoshik Analytical. Visit janoshik.com, enter the verification key, and the system will confirm the test results, batch identifier, and testing date.
What happens if a product does not have a current COA?
We are actively expanding COA coverage across our full catalog. Products with current third-party verification are clearly marked on their product pages. Check the COA status table above for the latest verification status of each compound.
How often are COAs updated?
A new COA is generated for each production batch. When we receive a new batch of any compound, a sample is sent to Janoshik Analytical before the batch is listed for sale. COA documents on product pages always reflect the currently available batch.
Can I request the full COA document for my order?
Yes. Contact support@mapleresearchlabs.com with your order number and we will provide the batch-specific COA documentation for every compound in your order.
