Miami Peptide Lab is a research peptide supplier that publishes the test results for everything it sells. All 30 Certificates of Analysis covering 23 products are free to download — no request form, no email, no account. That is the whole proposition, and the rest of this page is what it costs us to mean it.
Why we publish certificates instead of describing them
Almost every supplier in this category says their material is lab-tested. Very few will show you the document, and the ones that do usually send a single certificate on request, for a lot that may or may not be the one in the vial you receive. A purity figure you cannot trace to a lot number is a marketing claim wearing a lab coat.
So we publish all of them, tied to lot numbers, from 2 independent laboratories — including the lots that come in under our own 99% release target. Published lots currently measure 98.62–99.97%. A supplier whose published range never dips below its own standard is either extraordinarily lucky or only publishing the flattering results.
How you can check us without taking our word for it
- The laboratories are named, and neither is us. Vanguard Laboratory in Olympia, Washington is ISO/IEC 17025:2017 accredited under A2LA certificate #6377.01.01 — a number you can look up. Freedom Diagnostics reports HPLC-UV purity with LC-MS identity confirmation. Both print their own contact details on the certificate, so any result can be verified with the lab directly.
- Every certificate carries a lot number matching the vial, so the document belongs to the material you were sent rather than to a flattering batch from last year.
- Identity is tested, not just purity. A sample can be 99% pure and still be the wrong molecule. LC-MS confirms by mass that the vial contains what the label says.
- Prices are published in full. Every product and size is on one price list, generated from the live catalogue, so nothing is quote-on-request.
- Our writing tells you where it got its numbers. The editorial standards page sets out how the 43-article research library is sourced and what it will never contain.
What we sell
37 research peptides and reagents, shipped lyophilized and vacuum-sealed in insulated packaging with a cold pack, in a plain outer box with no product or company branding on the label. Vials are stored at −20 °C and protected from light before dispatch. US shipping is free over $150 and we ship worldwide at flat regional rates. Bacteriostatic water for reconstitution is sold separately, because it is a separate product and bundling it would hide the cost.
We are based in Miami and ship internationally. Orders are packed and dispatched by us, not by a third-party warehouse holding stock we have never seen.
What we will not do
These are materials for laboratory research. We are not a pharmacy, a clinic or a compounding facility, and we are neither permitted nor qualified to act like one. Nothing we publish will contain a human dose, a protocol, a treatment claim, or a comparison suggesting our material substitutes for an approved medicine — and if you find something that does, it is an error and we want to hear about it. We do not sell to anyone who tells us they intend to use these compounds in a person or an animal.
That costs us orders. It is the same trade as publishing the certificates that miss target: the claim is only worth something if it is expensive to make.
Common questions
Is Miami Peptide Lab a legitimate supplier?
Judge it from the documents rather than the description. All 30 Certificates of Analysis covering 23 products are published as free downloads, each tied to a lot number, from 2 independent laboratories — one of them ISO/IEC 17025:2017 accredited under A2LA certificate #6377.01.01, which is a number you can verify with A2LA directly. Both laboratories print their own contact details on the certificates they issue.
Where are you based and where do you ship?
We are based in Miami, Florida, and ship worldwide. US shipping is free on orders over $150 and $9.95 below that; international orders are charged a flat regional rate. Orders are packed and dispatched by us rather than by a third-party warehouse.
Do I need an account to see your test results?
No. Every certificate is a free PDF download linked from the product page it belongs to and collected in the certificate library. There is no request form, no email capture and no account requirement.
What purity do your lots actually measure?
Published lots currently measure 98.62–99.97% against a 99% release target. We publish the measured figure for every lot, including the ones that land under that target.
Can I use these products on myself or an animal?
No. Everything sold here is supplied strictly for laboratory research use. These are not drugs, foods, cosmetics or medical devices, they are not approved for any therapeutic, diagnostic or cosmetic purpose, and they must be handled only by qualified professionals in an appropriate research setting.
