Listing standards
US vendors must publish independent third-party testing for purity and endotoxins (capsule-only brands are assessed on other factors).
Outside the US, where third-party testing is less widely available, other factors determine eligibility for listing.
Each vendor's published testing coverage is shown on its profile and on the
vendors by testing page.
How prices are calculated
Prices are read automatically from each vendor's own storefront, most every four hours. Listings not re-confirmed within 48 hours are hidden. Totals are calculated by an optimizer that applies each vendor's multi-vial and mix-and-match discounts, the discount codes The Peptide Plug holds for that vendor, and shipping to the shopper's country.
How The Peptide Plug makes money
The Peptide Plug may earn an affiliate commission on purchases made through its links.
No vendor pays for placement or ranking. Price comparisons are ordered by price; the vendor testing list is ordered by published testing.
