FOUNDATIONAL GUIDE01
How to read a peptide COA
Use seven repeatable checks to separate identity, purity, measured content, lot traceability, sterility, endotoxin, and contaminant evidence.

Read the method—not just the headline.
Practical guides for verifying a certificate, understanding each analytical result, and recognizing where a polished COA stops short.
START HERE
Eight guides. Eight different questions.
Start with COA literacy, follow the lot-to-lab verification workflow, check whether the certificate matches the exact lot, then use the research-math series to understand U-100 units, mg-to-mcg conversion, and concentration inputs.
DOCUMENT AUDIT02
Nine peptide COA red flags
Find broken lot links, unverifiable laboratory records, label claims presented as measurements, missing methods, and overbroad pass claims.
Audit the red flagsMETHOD EXPLAINER03
Peptide testing methods explained
Understand what HPLC, LC-MS, quantitative content, microbial, endotoxin, ICP-MS, and targeted contaminant tests can—and cannot—show.
Compare the methodsRESEARCH MATH04
How U-100 syringe units are calculated
Follow the fixed 100-units-per-milliliter relationship from concentration to a user-entered target amount—without storing the values.
Understand U-100 unitsUNIT CONVERSION05
Milligrams vs micrograms
See why mg and mcg differ by a factor of 1,000 and how normalizing units prevents a calculation from drifting three decimal places.
Check the conversionCONCENTRATION MATH06
Why vial amount and liquid volume both matter
Use mass-per-volume reasoning to see why the same vial amount produces a different concentration when liquid volume changes.

How to verify a peptide COA online
Match a seller-hosted PDF to the issuing laboratory record, exact lot, analytical methods, results, and the test panels that remain missing.
Follow the verification chainTRACEABILITY CHECK08
Does a peptide COA lot number have to match?
See why a real report for a different lot is still the wrong evidence, which identifiers to compare, and what a match cannot prove.

Bring the next certificate with you.
Scan a COA for seven evidence signals or calculate a research concentration. Both tools run in the browser and keep their conclusions narrow.
