Peptide Library — Peptide Calculator

Reconstitution math with the syringe drawn to scale. Enter the vial strength, the diluent you added and the amount you are measuring. The Peptide Calculator shows the volume to draw in mL and in U-100 syringe units, with the nearest marking you can actually measure on the syringe you use. Or go the other way: enter a drawn volume and see what it holds. FEATURES • Amount → volume and volume → amount • Blends of up to eight components: draw for a combined amount, for one component, or see what a volume holds of each • 0.3, 0.5 and 1 mL insulin syringes and 1, 3 and 5 mL syringes, drawn on their real graduations • Warnings when a draw is below the smallest marking, between markings or more than the syringe holds • Recent results and named presets on your device; copy any result as text • Optional sync of saved calculations with the Peptide Library app (Pro) A CALCULATOR, NOT AN ADVISOR It never suggests, rates or limits an amount. IU and milligrams are converted only with the IU-per-mg factor of that exact substance; syringe units are not IU. SAME ENGINE AS THE APP The extension uses the calculation engine of the Peptide Library app and website, with exact decimal arithmetic. PRIVACY No access to the websites you visit.
