Why this exists.

The research peptide market is full of vendors and short on neutral evaluation. Most “best peptide” lists are affiliate-driven SEO. Caliber Peptide Index is the opposite: editorial ratings, no paid placement.

What we do

We track research peptide vendors and rate them on a single 0–100 score reflecting our editorial confidence in their transparency, documentation, and operational quality. New vendors are surfaced automatically; ratings are reviewed and updated daily.

What we don’t do

We don’t sell peptides. We don’t lab-test product. We don’t accept payment for inclusion or placement. Sponsored placements (when present) are clearly labeled and held to the same editorial standard as every other vendor.

How we’re funded

The site shows display advertising. We may also earn affiliate commissions when visitors click outbound links to vendor sites. Neither of these influences editorial ratings — a paying vendor receives the same evaluation as any other.

The disclaimers, plainly

Peptides discussed on this site are research compounds. They are not approved by the FDA for human consumption. Ratings are editorial opinion, not safety endorsements. Independently verify any vendor before purchasing.
