Every lot we sell is tested by an independent laboratory before it ships, and the certificates are published here in full. No request form, no email — 30 certificates covering 23 products, free to download.
Who does the testing
Two independent laboratories. Vanguard Laboratory (Olympia, WA) is ISO 17025:2017 accredited under A2LA certificate #6377.01.01 and reports chromatographic purity and quantity with a stated measurement uncertainty. Freedom Diagnostics reports HPLC-UV purity together with LC-MS identity confirmation. Each certificate below states which laboratory produced it, and its lot number.
Freedom Diagnostics, an independent analytical laboratory in the United States. They are not owned by, affiliated with, or paid per-result by Miami Peptide Lab — they are a third party, which is the entire point of third-party testing. Their contact details appear on every certificate so you can verify a result with them directly.
What is actually measured
Each sample is run by HPLC with UV detection, coupled to mass spectrometry (LC-MS). That produces three separate results:
- Identity (LC-MS) — confirms the vial contains the compound on the label, by mass. This is what catches a mislabelled or substituted product.
- Purity (HPLC-UV) — the percentage of the sample that is the target compound. Our released lots currently measure 98.62–99.97% against a 99% release target.
- Net content — the actual mass in the vial, against the labelled mass.
Each certificate also carries the raw chromatogram and mass confirmation traces, signed by the principal chemist. Those are the underlying data, not a summary of it — you can read the peak yourself rather than taking a number on trust.
Every published certificate
Every lot we sell is tested by Freedom Diagnostics, an independent US laboratory, by HPLC with UV detection coupled to mass spectrometry (LC-MS). Identity, purity and net content are all confirmed. Below are the 30 certificates for lot 261807, reported 24 July 2026. Each opens as a PDF — no request or email required.

Certificates are reproduced as issued by the laboratory, with the wholesale purchaser's identifying details removed. Testing results, lot number, dates, chromatogram and mass confirmation are unaltered. All products are supplied for laboratory research use only.
Why the buyer details are removed
We buy in bulk and the laboratory issues certificates to the purchasing account, so the original documents carry a wholesale client reference. That reference is removed before publication — it identifies a commercial counterparty, not the product. Everything that describes the material is untouched: laboratory name and contact details, accession number, lot number, received and reported dates, identity, purity, net content, chromatogram, mass spectrum and chemist signature all appear exactly as issued.
Reading a certificate
Four fields tell you most of what matters:
- Lot — ties the certificate to a specific production batch. Ours is currently lot 261807. A certificate with no lot number cannot be matched to anything you receive.
- Reported date — when the result was issued. A certificate several years old describes material that may no longer be in circulation.
- Identity — must name the compound you ordered. “Confirmed” against the wrong molecule is still a failure.
- Purity with a method — a percentage with no stated method is a marketing claim. Ours states HPLC-UV.
Our longer walkthrough, how to read a Certificate of Analysis, covers the rest.
Common questions
Is Miami Peptide Lab legitimate?
Every lot we sell is tested by Freedom Diagnostics, an independent US laboratory, and all 30 certificates are published on this page as downloadable PDFs — including the raw chromatogram and mass spectrometry traces, the lot number, and the laboratory's own contact details so results can be verified with them directly. We are based in Miami, Florida and ship nationwide. Products are supplied for laboratory research use only.
Are your peptides third-party tested?
Yes. Testing is performed by Freedom Diagnostics, an independent laboratory with no ownership or affiliation with us, using HPLC with UV detection coupled to mass spectrometry (LC-MS). Identity, purity and net content are each measured and reported separately.
How pure are your peptides?
Published lots currently measure 98.62–99.97% by HPLC, against a 99% release target. The exact figure for each product and size is listed on this page and printed on that product's certificate — we publish the measured number per lot rather than a single marketing claim.
Can I see a COA before I order?
Yes. Every published certificate is on this page and linked from its product page. No account, email or request is needed to view them.
Why has the client name been removed from the certificates?
We purchase in bulk, so the laboratory issues certificates to the purchasing account and they carry a wholesale client reference. That reference identifies a commercial counterparty rather than the product, so it is removed before publication. All analytical content — laboratory, lot, dates, identity, purity, net content, chromatogram and signature — is unaltered.
What lot do the current certificates cover?
Lot 261807, reported 24 July 2026. When we release a new lot the certificates here are replaced with that lot's results.
Research use only
All products are supplied strictly for laboratory research use. They are not drugs, foods, cosmetics or medical devices, are not for human or veterinary use, and are not approved for diagnostic or therapeutic applications. Certificates document material identity and purity — nothing more.
