Vendors sell different vial sizes — comparing sticker prices is misleading. A $30 vial of 5mg works out to $6.00/mg, while a $55 vial of 10mg is only $5.50/mg. The $55 option is actually cheaper per unit of research material.
📐 Formula: Discounted price ÷ mg = cost per mg
Example: $45 after discount ÷ 10mg = $4.50/mg. The table above calculates this automatically for every vendor, so you can compare apples to apples instantly.
When evaluating vendors for GHK-Cu, also check for: Certificate of Analysis (COA) availability, third-party HPLC or mass spectrometry verification, US-based shipping if timing is important, and responsive customer support.

Price variation reflects batch size, synthesis purity, third-party testing costs, and shipping infrastructure. Cheaper doesn't always mean lower quality — some vendors simply operate more efficiently. That said, always verify a Certificate of Analysis (COA) before purchasing from any vendor.
Divide the discounted price by the milligrams per vial. Example: $50 for 10mg = $5.00/mg, while $35 for 5mg = $7.00/mg. The $50 option is cheaper per unit even though the upfront cost is higher. Our table above handles this calculation automatically.
