What we test
Each certificate reports the results below for its lot. Purity and net content are on every certificate; the three safety screens are reported on 17 of the 52 lots listed — the card says which.
Shop tested compoundsHPLC / HPLC-UV
The share of the sample that is the named peptide, measured by high-performance liquid chromatography.
Measured mass per vial
How much compound the vial actually holds, reported in milligrams against the labeled strength.
Compound confirmation
Confirms the vial contains the compound on its label — and nothing else in its place.
Bacterial endotoxin screen
Screens for endotoxins left by bacteria. Reported as pass or fail.
PCR screen
Looks for microbial DNA in the sample. A clean result reads “No Detectable Microbial DNA”.
Heavy-metal screen
Checks for heavy-metal and elemental contamination. Reported as pass or fail.

COA questions
Something else? Contact our team with your lot number.
A COA is the laboratory's report for one production lot. It records what was tested, the method used and the result — for RIVN that is purity and net content on every lot, with identity, endotoxin, microbial and elemental-impurity screens on many.
Purity is the percentage of the sample that is the named peptide. Net content is the mass measured in the vial, which can sit slightly above the labeled strength. Safety screens read “Pass” or “No Detectable Microbial DNA” when clean.
The lot number is printed on the vial label. Search it in the library above, or open the product page and match it under Verified test results.
Certificates are published as each lot is tested. Send us the lot number from your label and we will send you its report.
Independent third-party laboratories. The laboratory's name and its own document are on every certificate — open the PDF to see the full report as the lab issued it.
Every product page links its lots and their certificates.
