Research use only. The Peptide Index is an independent research and price-transparency resource. All content is for informational and research purposes only. Nothing here is medical advice, and no product referenced is intended for human consumption or to diagnose, treat, cure, or prevent any condition.

Not a product-safety endorsement. A listing, price, or trust tier is not an endorsement of any product, vendor, or its safety, quality, or legality. We are not affiliated with, endorsed by, or sponsored by any vendor, brand, or company listed. Vendor names, logos, and trademarks belong to their respective owners and are used only for identification and commentary.

Public-record facts, presented neutrally. Trust signals and prices are compiled from publicly available sources (business registries, USPTO, domain/WHOIS and TLS records, published government enforcement records, and vendors’ own listed prices). We present these as neutral, sourced facts — not as accusations or claims of wrongdoing. A trust tier is a transparency signal, not a judgment; “Neutral” or a missing signal is not a negative finding. Data may be incomplete, out of date, or mis-captured.

No warranty, no liability. Information is provided “as is,” may be inaccurate, and is used at your own risk. We disclaim all warranties and are not responsible or liable for decisions made from this site.

Companies — this is your right of reply. If you operate a listed business and believe anything is inaccurate or out of date, we want to correct it. Submit a correction on your vendor profile (or contact us) with the correct information and a public source, and we’ll review and make good-faith adjustments promptly.
