The site names no company: its terms sign as Paramount Peptides and give 200 Spectrum Center Drive, Irvine, California, with California law and Orange County courts governing. California's registry holds an active Paramount Peptides LLC (file number 202359819086), a California limited liability company whose registered and mailing address is 2107 N. Broadway, Suite 104, Santa Ana, California. We could not establish whether that company runs the site.

Paramount Peptides gives its address as Irvine, CA on its own site. No company named; CA LLC of the same name found.

We searched the FDA's warning-letter index for “Paramount Peptides”, “Paramount Peptide”, “ParamountPeptides”, “paramountpeptides” and “paramountpeptides.com”, and openFDA drug enforcement records for the name and domain, and found no action naming Paramount Peptides or paramountpeptides.com. The three letters matching “Paramount” alone use the word in their text and concern unrelated companies.

Its COA lookup, open without a login, searches certificates by product or lot number; across our searches it listed 542 certificates with lot numbers, dated 17 September 2024 to 22 September 2026, naming Janoshik on 441 and Accumark Labs on 93 and no laboratory on 8. We opened three: a Janoshik report naming Paramount as client and manufacturer, and two Accumark Labs certificates, one of them among the 8. GLP products are listed under code names such as “GLP-2 T”, and the vial pictured on that certificate (lot 26RU010) is labelled “Tirzepatide 80 mg”. We did not confirm any certificate with the laboratory.

Three other domains run their own shops under the Paramount Peptides name: paramountpeptides.co (registered 19 March 2026), paramount-peptide.com (4 July 2026, as Paramount Peptides Lab, with a sales email on a misspelled domain) and paramountpeptides.net (17 May 2026). We could not establish whether any is connected to paramountpeptides.com, which does not link to them. paramountpeptide.com was registered on the same day and through the same registrar as paramountpeptides.com and now returns an error page. Of five other variants, paramount-peptides.com is parked, paramountpeptidesusa.com shows a launching-soon page, and three do not respond. The site this record covers is paramountpeptides.com.
