Behind the US Peptide Register
USA Peptide Companies keeps a register of US peptide companies. For each one it records what the company says about its location, its ship-from point and its testing lab, and links to the page that says it.
Publisher
USA Peptide Companies is published by Harry Stephens. It is one site with one job: keeping US claims apart. Being based in the US, shipping from the US and making a product in the US are three different claims, and the register shows each one separately.
Editor
Harry Stephens reads each company's contact, shipping, terms and lab report pages and writes the entries. Harry Stephens also handles every correction.
Funding
Some links on this site are affiliate links, marked as sponsored. If you buy through one, we may earn a commission at no extra cost to you. That has no effect on any score, stamp or fact. PSPeptides is shown as our pick, with its real score and rank next to it.
Rules of the register
The company's own words
Each entry records what the company says on its own pages about where it is based, where it ships from and who tests its lots. Every claim links to its source.
Not stated means not stated
If we cannot find a claim on the company's pages, the entry says Not stated. We do not guess, and we do not fill gaps from ads or forums.
Every entry is dated
Each check carries the date it was read. When a company changes a page, the entry is rechecked and the new date is shown.
One set of weights
Every company is scored the same way. The weights are published on the how we check page. See how we check.
Nothing bought, tested or used
We do not buy, test or use any product, and we never say we did. We also never publish anything about use in people or animals.
The full set of rules for sources, affiliate links and updates is in the editorial policy.
Research use only
Every company in the register sells its products for laboratory research. Nothing on this site is meant for people or animals, and nothing here is medical advice.
