How to read this table
Package shows vial count × labeled mg per vial. Price per mg divides the listed package price by the total labeled milligrams, so single vials and multi-vial kits can be compared directly. “COA” shows the testing lab a vendor lists; click it to open the vendor's published certificate where one is available. A lower price per mg does not by itself establish that two listings are equivalent.
Partner vendors (Daavy Research, Studz Peptides) show their referral code in the Code column. Codes never change the comparison fields or sort order.
