COA and Testing Standards

Effective date: May 13, 2026

Overview

PepSpex LLC intends to offer research-use-only materials with lot-specific documentation and quality review. This page explains the documentation standards PepSpex LLC expects to use at launch.

PepSpex LLC operates solely as a supplier of research-use-only materials. COAs, test reports, product names, product descriptions, purity references, and related documentation are provided for research material identification and quality review only.

Certificates of Analysis

Each qualifying product lot should have a Certificate of Analysis, commonly called a COA, that identifies the tested lot or batch. When available, COAs may include:

• Product name or identifier.
• Lot or batch number.
• Test date or report date.
• Purity result.
• Analytical method, such as HPLC or another appropriate method.
• Identity or mass confirmation method, such as LC-MS or another appropriate method.
• Lab, supplier, or testing-provider details.
• Storage or handling notes when applicable.

The COA for the specific lot controls over general website descriptions.

Purity and Identity

PepSpex LLC’s launch standard is expected to favor products with high-purity, lot-specific documentation. Where a product page references a target purity, that target is a product-selection standard and not a medical, therapeutic, diagnostic, or safety claim.

Purity values, identity confirmation, and related documentation are provided solely for research material review and quality documentation.

QR and Documentation Access

PepSpex LLC intends to support QR-verifiable documentation where available. QR links may lead to a product page, COA page, downloadable report, supplier document, or other batch-documentation resource.

If a QR code, COA link, or document appears unavailable or inconsistent, contact info@pepspex.com before using the material in any research workflow.

Supplier and Third-Party Testing

Testing may be performed by suppliers, contract laboratories, third-party laboratories, or other qualified testing partners. The source of testing documentation may vary by product and lot.

PepSpex LLC may review supplier documents, request additional documentation, reject lots, or pause product availability when documentation does not meet launch standards.

Research-Only Limits

COAs, purity results, identity reports, and product documentation do not establish that any product is safe, effective, sterile, pyrogen-free, endotoxin-free, injectable, ingestible, topical, diagnostic, therapeutic, or suitable for human or veterinary use.

All products are for research use only. They are not for human use, veterinary use, diagnostic use, therapeutic use, clinical use, food use, cosmetic use, dietary supplement use, or household use.

Document Questions

For COA questions, missing documents, or lot-verification requests, contact info@pepspex.com and include the product name, lot number, order number if available, and a clear description of the question.
