Clear about how this site works.

Affiliate disclosure

Some links may be affiliate links. If a qualified purchase is made through one of those links, Peptide Due Diligence may receive compensation at no additional cost to the purchaser. Commercial relationships do not determine which evidence is presented or the conclusions reached. Affiliate links will be labeled near the point of use.

Commercial safeguards

Affiliate availability, commission rate, free products, and sponsorship offers do not change the review criteria or evidence record. The relationship is recorded before a conclusion is reached. A partner may be excluded or removed when current documentation no longer meets the publication threshold.

Research-use boundary

Peptide Due Diligence is an independent educational publication. Any non-approved peptide, supplier material, or product designated Research Use Only (RUO) that is discussed or linked on this site is referenced strictly for qualified laboratory and in-vitro research. Such materials are not intended for human or veterinary use, consumption, compounding, diagnosis, treatment, cure, or prevention of disease.

We do not provide protocols for personal use, dosing or administration instructions, medical advice, or a substitute for the judgment of a qualified professional. A supplier listing, external link, affiliate relationship, research summary, or discussion of a published study does not establish that a material is safe, effective, sterile, lawful, or suitable for any particular use.

Product-specific status

“Research Use Only” is an intended-use designation, not a universal description of every peptide molecule. Some molecules discussed in the scientific literature may also exist in separately regulated or approved products. Status attaches to the exact product, labeling, intended use, and jurisdiction. Readers must verify current official records and supplier terms rather than infer status from a molecule name alone.

Educational scope

Peptide Due Diligence publishes general educational analysis of laboratory documentation, analytical methods, supplier transparency, scientific literature, and public regulatory information. Content is not individualized medical, legal, regulatory, or professional laboratory advice.

Editorial limits

Public supplier documents and prices can change without notice. A listed certificate of analysis does not independently establish identity, quantity, sterility, safety, efficacy, regulatory compliance, or fitness for a particular protocol. Readers remain responsible for independent verification and applicable institutional and legal requirements.
