Community roundup: we summarize and fact-check what the peptide community discusses on Reddit and research forums, then add the exact reconstitution math and handling notes.

The most-repeated reconstitution question on Reddit is simply: how much water, and how many units. The math is one formula, and a calculator removes the guesswork.

The formula

Concentration equals milligrams in the vial divided by millilitres of bacteriostatic water. A 10 mg vial with 2 mL is 5 mg/mL. From there, units are just volume on the U-100 scale.

Let the calculator do it

Our peptide calculator turns any vial-and-water combination into concentration, units to draw, and draws per vial instantly, and it has a table of common starting concentrations you can load with one tap.

Compound-specific notes

Some compounds need special handling; the Peptide Reference Library flags which ones gel or need an acidic solvent.
