The checks

What we checked on PSPeptides

Five checks against outside records. Open any finding to see the source.

  1. Operating historyOnline since April 2026; domain registered November 2025
    Partly confirmed

    pspeptides.com was registered on 10 November 2025 through Porkbun. The Wayback Machine's first capture of it is from 14 April 2026, a PSPeptides shop with prices that said it had shipped 5K+ orders; it has been captured again in June, August and September 2026. Its about page says it has been in business for more than five years, and its earliest published lab report is dated 20 October 2025, before the domain was registered. We found no earlier domain for the shop.

    Checked 7 Oct 2026

  2. Business registrationNo company named on the site
    Not disclosed

    The terms, privacy policy, contact and about pages name no company and give no street address; they refer only to PSPeptides, and the about page says a 25-person team is based in New Jersey. Its lab reports name the client as “ProSupply Peptides” and “ProSupply Research”. New Jersey's business name search shows no entity named ProSupply Peptides, ProSupply Research, PS Peptides or PSPeptides, and we found none under those names on OpenCorporates.

    Checked 7 Oct 2026

  3. Regulatory recordNo FDA warning letters or recalls found
    None found

    We searched the FDA's warning-letter index and openFDA drug enforcement records for the name and the domain and found no action naming PSPeptides or pspeptides.com.

    Checked 7 Oct 2026

  4. Testing transparencyMain lab is new and carries the shop's own IDs
    Worth knowing

    Its certifications page, open without a login, links 543 report files, each giving a batch or lot number. 538 are from North American Diagnostics, which gives an Austin, Texas address: 190 purity and identity certificates across 164 batches, dated 20 October 2025 to 25 September 2026, and 348 endotoxin, heavy-metal, sterility and fentanyl screens. Five are from Vanguard Laboratory of Olympia, Washington, reported 28 September 2026. The laboratory's website, nadiagnostics.com, was registered in June 2026 and uses the same Cloudflare name servers as pspeptides.com; we could not establish who owns it, and did not confirm any report with either laboratory.

  5. Other sites using the name1 live shop uses the name
    Worth knowing

Its lab reports name the client as “ProSupply Peptides” and “ProSupply Research”. New Jersey's business name search shows no entity named ProSupply Peptides, ProSupply Research, PS Peptides or PSPeptides, and we found none under those names on OpenCorporates.

Has the FDA taken action against PS Peptides?

We searched the FDA's warning-letter index and openFDA drug enforcement records for the name and the domain and found no action naming PSPeptides or pspeptides.com. We also searched “PS Peptides”, “pspeptides”, “ProSupply”, “ProSupply Peptides” and “ProSupply Research” and found nothing naming it.

Does PS Peptides publish COAs (lab test results)?

Its certifications page, open without a login, links 543 report files, each giving a batch or lot number. 538 are from North American Diagnostics, which gives an Austin, Texas address: 190 purity and identity certificates across 164 batches, dated 20 October 2025 to 25 September 2026, and 348 endotoxin, heavy-metal, sterility and fentanyl screens. Five are from Vanguard Laboratory of Olympia, Washington, reported 28 September 2026. The laboratory's website, nadiagnostics.com, was registered in June 2026 and uses the same Cloudflare name servers as pspeptides.com; we could not establish who owns it, and did not confirm any report with either laboratory.

Gaps

What we couldn't verify about PSPeptides

  1. 01Which company runs the shop, and where: the site names no company or street address, and the name on its lab reports, ProSupply Peptides, matched no registered entity we found.
  2. 02Where it traded before pspeptides.com was registered in November 2025, given its claim of more than five years in business and a lab report dated October 2025.
  3. 03Who owns North American Diagnostics, whose website shares the shop's Cloudflare name servers, and whether any report has been confirmed by the laboratory that issued it.
  4. 04Whether pspeptides.co, a page-for-page copy of the shop, is run by the same operator.
