Reconstitution volumes, concentration and U-100 unit equivalents for TB-500.
These examples explain unit relationships in published research and are not instructions for preparing, measuring or administering any compound. Do not use this information to self-administer research chemicals.
Worked at 2.00 mg, the amount reported in the research for TB-500. Every row is the same arithmetic: milligrams in the vial divided by millilitres of water gives the concentration, and the target amount divided by that concentration gives the volume.

List prices, checked September 4, 2026. Sale pricing is ignored on purpose so the table does not swing week to week. Verify before ordering.
Suppliers are listed alphabetically. We do not rank them by price, because the cheapest vial and the one worth buying are rarely the same thing. The column that matters is the last one, and today most of it reads "none on file", including for Quartz Peptides, which is owned by this site’s editor. See the disclosure and the COA guide.
