Tested by a lab that answers to an accreditation body, not to us
Freedom Diagnostics, an independent analytical laboratory in Franklin, Tennessee. Every report runs HPLC for purity and LC-MS for identity confirmation, and each is signed by the chemist who ran it. They hold no commercial relationship with our suppliers — a supplier's own report isn't independent verification. Every COA we receive is searchable by accession number in Freedom's public database, so you can confirm the report against the lab's own records rather than taking our copy of it on faith. We post results as received, including any that come back below expectation.
Compound identity
Confirms the vial contains the compound named on the label, at the stated molecular weight.
Purity and content
Measures how much of the vial is the target compound versus synthesis by-products and degradation.
Storage and handling
Lyophilised product is held at temperature and packed with insulation where transit conditions require it.
Lot traceability
Every vial carries a lot code that maps to its COA on the testing page.
About Sera Peptides
Sera Peptides Holdings LLC supplies research compounds to laboratories and independent researchers in the United States. We're small, we're owner-operated, and we'd rather be the vendor that tells you what it doesn't know than the one with the biggest number on its homepage.
Each product page links the Freedom COA for that lot. If a report isn't back yet, the page says so instead of quoting a number from a different batch.
We stock a short list of compounds we can document properly rather than a wall of SKUs we can't stand behind.
Email a question about a lot and you'll get a reply from the person who packed it — usually the same day.
