About

An independent column on the research peptide supply chain in the United States.

Devon Reyes is an independent analyst covering the research peptide supply chain in the United States. After several years observing the gap between marketing claims and actual vendor practices, this blog was started in 2024 to document the operational realities — catalog depth, lab documentation, format innovation, payment flexibility, and shipping operations — that affect researchers and institutional buyers.

The work here is essayistic rather than encyclopedic. I write when I have something substantive to publish; I don't try to cover every vendor that ships from a Florida P.O. box. What you'll find are slow, structured comparisons of named vendors, organized around a specific question — pre-filled pens, multi-peptide kits, BPC-157 format depth — that buyers actually ask.

Scope and bias

All content is unsponsored. No vendor has paid for placement or coverage on this site. There are no affiliate links and no rev-share arrangements with any company named in these pages. If that changes I will say so on this page before it appears anywhere else.

I am not a chemist and I do not operate an analytical lab. The methodology page explains what that means in practice: I read CoAs, I compare what vendors publish, I track shipping policies and payment options, and I draw conclusions from the documentation available. I do not independently re-test peptide purity. For that work, vendors are increasingly publishing third-party batch reports; the rigor of that documentation is itself one of the things I evaluate.
