What Does Your Peptide COA Really Tell You?
Dirty Peptides independently review existing Certificates of Analysis (COAs) and supporting laboratory documentation to identify what is reported what may be missing and potential inconsistencies. We do not perform laboratory testing or certify 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 flag what is reported, what may be missing, unexplained peaks, or missing potency data. These findings help identify questions that may deserve further investigation.
Heavy Metals & Batch Traceability
We review whether heavy metal testing, batch information, lot numbers, laboratory details, and other traceability information are reported. Missing or inconsistent documentation is flagged for closer review. We do not independently verify the product or laboratory results.
Our Independent COA Review Process
STEP 01
Lab Documentation Review
We review the laboratory information reported on the COA, including the laboratory name, testing methods, dates, and available supporting documentation, and flag missing or inconsistent information.
STEP 02
Batch Traceability
We review batch identifiers, lot numbers, dates and other traceability information reported across the COA and supporting documentation and flag missing or inconsistent information.
STEP 03
Heavy Metals Analysis
We review whether heavy metal testing is reported, which metals were evaluated, the reported results, and any stated testing limits or methods. Missing or incomplete information is flagged for closer review.
STEP 04
Endotoxin & Sterility Review
We review whether endotoxin and sterility testing is reported, including the test methods, reported results, and stated specifications. Missing or incomplete information is flagged for closer review. We do not independently verify sterility or product safety.
Science-Verified Insight
"A COA can provide valuable information-but only if you know what to look for, what may be missing, and what the reported results actually mean."
