§ The Sources · All vendors

The vendors, indexed & annotated.

Every vendor we reference in the research peptide market, with current shipping & COA notes and the confidence we have in each — none of them paid to be here. Confidence reflects sourcing transparency and COA freshness, not a discount. For live per-mg pricing, open the free tool.

§ Our Confidence Rating

How we rate confidence. Each badge blends the same signals for every vendor — third-party COA coverage, independent batch testing, how long the vendor has operated, and outside directory listings. The dot is the short version; the full per-vendor scoring breakdown lives inside the free tool, where it stays current alongside live per-mg pricing. Inclusion here is informational, not an endorsement — verify directly with the vendor before buying.

All content on Peptide Price Lab is for informational and research purposes only. Nothing here constitutes medical advice, and research peptides are not intended for human use. Vendor information is provided as a reference and may be out of date. Always consult a licensed healthcare provider and verify information directly with vendors. Where we hold an affiliate code, we surface it only when it beats a vendor's current sale; using it never costs you more.
