Method Biolabs LLC is a United States supplier of research-use-only peptides and reference materials, serving researchers and institutional buyers.
What we do differently
In this category every supplier claims purity and almost none of them prove it. We publish the proof.
Every lot is tested by Freedom Diagnostics, an independent laboratory in Franklin, Tennessee: purity by HPLC, identity by mass spectrometry. You can confirm any of our certificates on the lab’s own Certificate of Analysis Lookup with the Search Code printed on it.
Every lot we sell has its certificate of analysis published in full as soon as its results are in, and it stays published. The first certificates are coming soon. Each certificate states plainly which laboratory tested the lot and who supplied the sample. We commission independent third-party testing and publish those results on the same lot page as they come back.
Every order names the lot each item ships from, and once its certificate is up, that lot number retrieves it at methodbiolabs.com/lots in one search. No account, no email address, no request form. If you bought it, you can verify it, and so can anyone else.
We publish what the testing shows, including when it is not what we hoped. A verification claim is worth nothing if the verifier only publishes the good results.
What we do not do
We do not tell you what to do with what we sell. Every product is supplied for laboratory research use only, and we do not provide dosing, administration or protocol guidance to anyone, through any channel, ever.
We do not make claims about physiological effects. We do not publish testimonials about personal results. We do not seed ratings or write our own reviews.
We describe products by compound identity, stated mass, purity as reported on that lot’s certificate, and lot number. That is the whole description, and it is the only one we think is honest.
