About PeptideIndex

PeptideIndex is a B2B directory for people sourcing peptides: biotech teams looking for a CDMO, brands looking for a manufacturer, and labs comparing research suppliers.

What we do

• Review each listing by hand against the supplier's site, lab reports and public records.
• Publish a score with the evidence behind it. See how scoring works.
• Track regulatory notices such as FDA warning letters and show them on affected listings.

What we don't do

• We do not sell peptides or take a cut of orders.
• We do not give medical or dosing advice. Research-use-only products are not for human consumption.
• Paid placement never changes a score.

Corrections: email the address on the submission page with links to evidence.
