Peptide Reconstitution, Dose & Blend Calculator
Pick a compound, the amount per dose in the protocol, and the frequency. The calculator shows how long a vial lasts at that rate, how much bacteriostatic water yields a clean draw, and the syringe units that volume corresponds to. Separate blend tab for multi-compound vials.
This tool performs concentration and volume math for laboratory reconstitution of research compounds. It is not dosing guidance for any person.

Peptide per draw
How to read this (and why the math works)
How long a vial lasts = vial size ÷ amount per dose, spread across the frequency. A 10 mg vial at 2 mg per dose is 5 doses — about 5 weeks at once-weekly frequency. This does not depend on the water — adding more or less water never changes how many doses are in the vial.
What the water changes is the volume per dose. Concentration = mg of peptide ÷ mL of water. More water = a more dilute solution = more units pulled per dose; less water = fewer units. The calculator suggests a water amount that makes each dose land on a clean, easy-to-read number of units.
Syringe units. Every insulin syringe is marked so 1 unit = 0.01 mL. The U-100 / U-50 / U-30 choice only changes the barrel size and the marks you read against — the unit number for a given volume is the same.
Blends. In a multi-peptide vial, each compound has its own concentration (its mg ÷ the shared water). Every draw delivers all of them in proportion.
Reconstitution etiquette: let the water run down the inside wall — don't spray it onto the powder. Swirl gently, never shake. Store reconstituted vials in the fridge.
