A The work

Harry Stephens runs the register on this site. For each company, Harry reads the contact, shipping, terms and lab report pages and writes down what the company itself states about its location: a business address, a ship-from state, a place of manufacture, and the lab named on its certificates of analysis.

When a company does not state something, the register says "Not stated". When two pages on one site disagree, both statements are shown. Every entry links to the page it came from, with the date it was read.

Harry does not buy, test or use any product, and does not visit company premises. Everything on this site is sold for research and laboratory use only.

B Why Harry keeps a register

Plenty of peptide sellers put "USA" in their name or a flag on the label. Far fewer say where the company is, where orders leave from, or where the lab that tested a lot is located.

This site keeps those claims apart and checks each one against the company's own pages. It does not test products, so it cannot confirm where anything was made. It can show what each company says and where it says it.
