peptide reconstitution calculator

powder plus water makes a strength. enter what is in the vial, the peptide mass and the bacteriostatic water you added, and this tool shows the concentration in mg/ml and how a given amount in mcg converts to units on a u-100 insulin syringe. it is generic concentration math for keeping your own research records, not an injection instruction and not medical advice.

how to reconstitute a peptide

1. enter the peptide mass. set the labeled mass of the peptide in the vial, in milligrams. the generic vial-size chips set the mass only, with no implied amount.
2. enter the bacteriostatic water. set how much bacteriostatic water you added, in milliliters. more water makes a weaker solution that reads as more units; less water makes a stronger one.
3. read the concentration. the tool computes the concentration in mg/ml and how many micrograms that works out to per unit on a u-100 syringe.
4. convert an amount to units. enter the amount you want to convert, in mcg, to see how many units that lands on the barrel. a unit is one tick on a u-100 insulin syringe, where 100 units equals 1 ml.
5. match your syringe barrel. pick the barrel you have (0.3 ml, 0.5 ml, or 1 ml) to see exactly where the draw falls, and use the even-units suggestion to land on a clean mark.

frequently asked questions

what is peptide reconstitution?

reconstitution is mixing a dry peptide powder with a sterile liquid, commonly bacteriostatic water, to make a solution of a known strength. this calculator does the concentration math: mass in, water in, strength out.

how much bacteriostatic water should i add?

there is no single correct amount. more water makes a weaker solution that reads as more units on the syringe, which is easier to measure for small amounts. less water makes a stronger solution. the calculator shows the trade-off as you type so you can pick a volume that lands on an easy-to-read mark.

how do i convert mcg to units on an insulin syringe?

units are the ticks on a u-100 insulin syringe, where 100 units equals 1 ml. once the concentration in mg/ml is known, the calculator converts any amount in mcg into the units you would draw and shows where that falls on the barrel.

is this medical or dosing advice?

no. this is a generic concentration-math utility for research record-keeping. it carries no compound-specific protocols, you enter your own numbers, and nothing here is an instruction to draw or inject. peptides referenced are research-use-only.
