Comparison method
How to compare retatrutide suppliers
“Best” and “cheapest” are not useful labels unless the basis is visible. The WTB table makes the fields visible so a reader can decide which listings merit a closer look.
A short, repeatable check
- Match the peptide and package. A five-vial kit and one vial are different listings even if the product name is the same.
- Compare price per mg only after confirming the vial count and milligrams per vial.
- Open the vendor page. The price, stock status, and product options can change after the WTB data refresh.
- Read the documentation field literally. “Independent COA listed” means a linked or recorded claim in the comparison data; it is not a product-quality guarantee.
- Check the referral-code column. A code identifies a partner relationship and does not alter the underlying fields.
Why the table does not rank a winner
A single rank would hide tradeoffs. A listing with a low package price may have less material. A larger kit can lower the price per mg but ask for more money up front. Documentation and payment information are separate facts. Keeping them separate is more useful than rolling them into a score.
