How much water should I add to a vial?

There is no single right amount. The volume you add sets the concentration, and more water simply spreads the same peptide across a larger volume, which can make small amounts easier to measure. Our reconstitution calculator does the arithmetic for you from the vial strength, the water you add, and your target amount. It is a math tool and does not recommend a dose.
