Independent Peptide
COA Review
Understand what your peptide COA reports, what may be missing, and the red flags worth a closer look.
What Does Your Peptide COA Really Tell You?
Dirty Peptides reviews and interprets existing Certificates of Analysis (COAs) and supporting laboratory documentation. We do not perform laboratory testing and do not certify or guarantee safety, sterility, efficacy, or suitability for human use.
Identity Verification
We review the identity information and analytical methods reported on the COA and supporting documentation, and flag mismatched names, incomplete methods, missing identity data, or other inconsistencies. A COA does not prove a peptide is safe or suitable for human use.
Purity & Potency
We review purity and potency information such as HPLC purity %, peptide content, and related impurities. We highlight what’s reported, what may be missing, and issues like very low purity, unexplained peaks, or no potency data at all. These findings help you understand product quality but do not confirm safety for human use.
Heavy Metals & Batch Traceability
We review whether sterility and endotoxin testing is reported, the methods and results provided, and any stated laboratory specifications or reference limits. We flag missing testing, incomplete information, or results that warrant further review. Even with this information, a COA alone cannot prove a peptide is safe for human use.
Our Rigorous COA Verification Process
STEP 01
Lab Verification
We independently verify that the certificate was issued by an accredited laboratory for the specific testing performed, confirming the institution's legitimacy and credentials.
STEP 02
Batch Traceability
Our experts cross-reference batch identifiers and lot numbers across technical documentation to ensure the peptide being tested accurately corresponds to the supplied COA.
STEP 03
Heavy Metals Analysis
We review ICP-MS results for trace elements like arsenic, cadmium, lead, and mercury, evaluating their concentration against established scientific reference standards.
STEP 04
Endotoxin Testing
Identification of bacterial endotoxins via LAL test results is crucial. We verify that sterility levels are appropriately documented and within technical specifications.
