Certificates of Analysis (COA)
At Retat Core, quality, transparency, and scientific integrity are at the core and top priority in everything we do and stands for. We are committed to providing full confidence in the research Petides materials which we supply. We ensure all products undergo rigorous third-party testing and verification.
We proudly source from reputable manufacturers, including trusted brands such as PureRawz, Alluvi, alongside other established research-grade suppliers. Every batch is independently tested to confirm purity, identity, and consistency before being made available for research use.
Independent Third-Party Lab Testing
To maintain the highest standards, all peptides and compounds are tested by independent, accredited laboratories. These third-party facilities operate with no affiliation to manufacturing processes, ensuring unbiased and accurate results.
Each Certificate of Analysis includes:
Verification of compound identity
Batch-specific traceability
Detailed purity assessment
Confirmation of molecular structure
Purity Verification
Purity is a critical factor in research reliability. At Retat Core, every product must meet strict purity thresholds before release.
Our COA reports typically confirm:
High-performance purity standards (typically ≥ 98%)
Absence of harmful contaminants
Batch consistency across production cycles
Compliance with research-grade specifications
Only products that pass full analytical screening are approved for distribution.
Analytical Testing Methods
All verification is conducted using advanced analytical techniques, including:
High-Performance Liquid Chromatography (HPLC)
Used to determine compound purity and detect any impurities or degradation products with high precision.
Mass Spectrometry (MS)
Used to confirm molecular weight and structural identity of each peptide or compound.
Additional Analytical Methods (where applicable)
Depending on the compound, additional testing may include:
UV spectroscopy
Amino acid analysis
Stability testing
Microbial screening
Brand Transparency – Including Alluvi & Other Trusted Suppliers
Retat Core partners only with reputable, research-focused manufacturers such as Alluvi and other verified suppliers who adhere to strict production and quality control standards.
Every batch, regardless of brand origin, is independently verified through third-party COA testing before being approved for research distribution.
Access to COA Reports
COA documents are available upon request or may be provided alongside specific product batches. Each report corresponds to a unique batch number for full traceability and transparency.
