Your trust is our priority. We ensure complete transparency by providing comprehensive certificates of analysis (COA) for each batch so that you know exactly what goes into your research.

  • In an industry where accuracy is paramount, we rely on facts. Using high-performance liquid chromatography (HPLC), we confirm that the active ingredient content is at least 99% pure. This eliminates fillers and impurities, ensuring the purity of every dose. In an industry where accuracy is paramount, we rely on facts.

  • Purity requires confirmation of authenticity. Using mass spectrometry, we verify the molecular structure and amino acid sequence. This is the only way to ensure that the peptide has the correct biological activity and is exactly what it claims to be. Purity requires confirmation of authenticity.

  • Our commitments extend beyond the moment of production. We conduct formula stability tests to ensure that the product does not degrade during transport and retains its properties throughout its shelf life, regardless of external conditions.

Our testing process

1) Production audit

We don't just purchase raw materials, we check the manufacturers. We only work with certifiedfactories that comply with GMP standards to eliminate defects at the outset.

2) Blind sampling

To ensure full objectivity, we select random samples directly from the finished production batch for independent laboratory testing. No special “golden samples” are prepared, the same product customers receive is the product submitted for analysis.

3) HPLC and MS analysis

Samples undergo independent third-party laboratory verification. High-performance liquid chromatography (HPLC) confirms ≥99.3% purity, while mass spectrometry (MS) verifies molecular identity and structural accuracy.

4) Certification (COA)

After successful testing, each production batch is issued a Certificate of Analysis (COA). This document is made publicly available and linked directly to the corresponding product page for full transparency.

The testing standards we follow

HPLC

Purity Analysis

We use High Performance Liquid Chromatography to ensure that the active substance concentration is ≥99% and that there are no foreign impurities.

Mass Spectrometry (MS)

Substance Identification

Mass spectrometry (MS) is used to confirm the exact molecular weight and molecular identity of the compound, verifying the correct amino acid sequence and ruling out substitution or structural inconsistencies.

Independent audit

Partner: Janoshik Analytics

Samples are independently tested by our third-party laboratory partner, Janoshik Analytics. Certified analytical reports are issued and made publicly available to ensure full transparency and independent verification.
