Vendor Directory
259 active vendors tracked. Tier ratings are research-based, sourced from independent testing data and community consensus.
Vendors marked Partner pay Peptul a commission and are listed first in this order. Paying does not change a vendor’s trust tier, COA badge, Peptul Score or reviews - those come from evidence and are worked out the same way for every vendor.
