Overview

The site states that Horizon Analytical LLC, a Delaware limited liability company with an address in Golden, Colorado, provides analytical testing services for products such as peptides and dietary supplements. Advertised services include HPLC/MS purity, chemical identity, mg quantitation, and endotoxin testing, with heavy metals and sterility listed as 'coming soon' on the homepage while appearing as orderable services elsewhere, including a 'Full Panel.' The compliance policy states sterility testing is currently performed by a named subcontractor, SD PharmLabs, and heavy-metals work may be done by Horizon or another outside laboratory the site says it works with. Turnaround figures differ between pages, ranging from 48 hours to 25 days depending on the service. The site offers a public certificate-verification tool by lot or report number and lists published prices for individual tests and bundles. No accreditation is claimed. Details are summarised from the company's own website and have not been independently audited.

  • The Golden, Colorado address is published as the company's business address in its terms of service; the site does not say whether testing is performed there.
  • Horizon Analytical's website shares template copy with ChromaSys Analytical; PAL has not established whether the two are related.

Is this your facility?

Claiming is free. PAL first verifies that you are authorized to act for the business. Verified owners can then use three separate routes. Peptide Ad Lab never charges a business to correct a factual inaccuracy.

  • Company-provided updatesYour description, testing services, methods and instruments, facility locations, sample submission link, turnaround, pricing and contact details, shown in a section labelled “Provided by the company”. Not checked by PAL and not used in the score. Free: sent to PAL as correction requests. PAL Pro: published directly.
  • PAL-reviewed evidenceDocuments or links for a scoring criterion. PAL reviews them under the same rule used for every facility; only accepted evidence changes a finding. Any plan.
  • PAL-verified lab credentialsAccreditations such as ISO/IEC 17025. They count only after PAL finds them in the accreditor’s public directory. Any plan.

PAL Pro is an optional paid plan for company-provided updates, extra images and the PAL Pro badge. It never verifies a credential, accepts evidence, or changes a finding, score, eligibility or ranking position.

Ownership verification confirms that you control the business. It is separate from laboratory credentials and from PAL Pro, it is not an endorsement, and it does not change any finding or score.
