Compliance & Testing Policy

Horizon Analytical Terms of Service

Effective Date: August 24, 2026

Effective Date: August 24, 2026

This Policy summarizes how Horizon Analytical LLC handles samples, testing, reports, public certificates, and laboratory claims. It supplements the Terms of Service and each accepted Order.

1. Scope and Independence

Horizon provides analytical testing for commercial, consumer, and research customers. Standard Services are not clinical or diagnostic testing and do not accept patient specimens or patient-identifiable health information.


Horizon is independent of Direct Peptides. Direct Peptides and other customers do not control Horizon's methods, quality review, results, or reporting.

2. Current Testing Model

Depending on the accepted Order, Horizon may provide:


  • purity testing by the chromatographic method listed on the report;

  • chemical identity testing by the technique and acceptance basis listed on the report;

  • quantity or concentration testing with the reported units and method basis;

  • endotoxin testing using a dedicated method;

  • heavy-metals testing by Horizon or an identified approved outside laboratory; and

  • sterility testing, currently performed by SD PharmLabs unless the Order identifies another provider.


The Order and report will identify what was tested, the method or method reference, result and units, important qualifications, and whether work was performed by Horizon or another laboratory. Horizon does not claim a method, accreditation, certification, license, validation status, detection limit, or turnaround unless current records support the exact statement.

3. Sample Acceptance and Quality

Customers must provide accurate sample identity, hazards, storage needs, requested tests, and custody information. Horizon may reject, quarantine, qualify, return, or dispose of a sample that is unsafe, unlawful, damaged, mislabeled, unstable, insufficient, or outside the accepted scope.


Controlled substances, hazardous materials, human-derived materials, and international shipments require prior written approval and all required permits and documentation. Patient-specific diagnostic work is not accepted under the standard Services.


Testing uses documented procedures, qualified personnel, suitable equipment, reference materials, and quality controls appropriate to the method. Material deviations or qualifications will be documented in the report. A result applies only to the submitted sample under the stated method and does not by itself establish safety, efficacy, legality, regulatory approval, or whole-lot conformity.

4. Reports, Corrections, and Public Certificates

Reports receive technical review before release. Horizon may investigate atypical or quality-control results and may correct, replace, or withdraw a report. Revised reports preserve revision status and supersede earlier versions.


Reports and certificates are private by default. Public verification requires the customer's opt-in authorization and displays only approved information. Customers may not alter a report, remove qualifications, apply a result to another lot, or imply Horizon endorsement, government approval, or a broader finding than the report supports.

5. Claims and Badges

Horizon will not use "FDA approved," "FDA certified," "ISO accredited," "certified," "compliant," cGMP, GLP, DEA-licensed, CLIA, or similar wording or badges unless the exact claim, legal entity, site, method, scope, dates, and supporting evidence have been verified.


Customer-facing descriptions must distinguish Horizon's own status from an employee's credentials, an instrument or vendor's status, and a subcontractor's accreditation or license. A subcontractor's status does not transfer to Horizon.

6. Records and Complaints

Horizon retains final reports, chain-of-custody records, and supporting raw analytical data for at least five years after the report date, unless a longer period is required. Access is limited to authorized personnel, and corrections must preserve an audit trail.


Questions or complaints should be sent to contact@horizonanalytical.com within 15 days of report delivery with the Order, sample or lot identifier, report version, and concern. Retesting depends on retained sample quantity, stability, and an agreed investigation plan.

7. Policy Updates and Contact

Horizon may update this Policy as capabilities, methods, subcontractors, or law change. An accepted Order will not be materially changed without customer agreement.
