Janoshik Verified Test Reports
Every batch independently tested by Janoshik Analytical using HPLC and Mass Spectrometry. 99.5%+ purity confirmed across our entire product range.
What Is HPLC Testing?
High-Performance Liquid Chromatography (HPLC) is the gold standard for compound analysis. It separates, identifies, and quantifies each component in a sample, providing precise purity percentages. Our reports consistently show 99.5%+ purity across all product lines.
Why Independent Testing?
All testing is performed by Janoshik Analytical, a fully independent third-party laboratory in the Czech Republic. They have no financial ties to GYC, meaning every result is unbiased and verifiable. Each report includes a unique verification link you can check directly on Janoshik's website.
Our Testing Process
Every manufactured batch is sampled and shipped directly to Janoshik for analysis. Reports cover compound identity confirmation, purity percentage via HPLC, mass spectrometry verification, and heavy metals screening. Only batches that pass are released for sale.
