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.

Based on our current data across 25 vendors, AtomiK Labz currently offers the best cost-per-mg — $2.46/mg when you use code Glowlab15. Always compare $/mg rather than sticker price since vial sizes vary significantly.
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.
