Peptide reconstitution & dosing calculator

Enter what is in the vial, how much bacteriostatic water you added, and the dose you want. The calculator returns the exact syringe reading, how many doses the vial holds, and how long it lasts.

Peptide preset Loads a typical vial size and starting dose. Always confirm against your own vial label and your prescriber's instructions.

Peptide in the vial Read this off the vial or the label. It is the dry powder amount before any water is added.

Bacteriostatic water added The volume you inject into the vial to dissolve the powder.

Dose you want per injection

Syringe

U-100 insulin syringes. 100 units = 1 mL.

Injection frequency Used to work out how long one vial lasts.

How to use the reading. Pull the plunger back until the top of the black stopper sits on the line shown above. Draw slowly, tap out air bubbles, and push back to the line before injecting.

Accuracy. Doses under about 3 units on the syringe are hard to measure reliably. If your reading is that small, add more bacteriostatic water to the next vial so the same dose fills a larger, easier-to-read volume.

Not medical advice. This tool performs arithmetic on the numbers you enter. It does not verify that your dose, peptide, or protocol is appropriate. Confirm everything with the prescribing clinician and the product label before injecting.
