Reconstitution calculator
Powder, pre-mixed, or blend vials → the exact units to draw on a U-100/U-40 syringe, the concentration, and how many doses your vial holds. You enter the numbers; it does the math.

The peptide math,
done for you.
Enter your vial, your water, and your dose — PeptideBro shows the exact units to draw on a visual syringe. Powder, pre-mixed, or blend. Plus private site-rotation, reminders, and weight & outcome tracking.
Site-rotation map
See at a glance which injection zones are ready, recovering, or recently used — based on standard cooldown windows — with optional reminders.
Progress & outcomes
Log your weight and how you feel and chart the trend over time, so you can actually see whether your protocol is working.
Private by design
No account, no analytics, no ads. Your log lives on your device, with optional backup to your own private iCloud — we never receive it.
Educational reference and a math utility. Not medical advice. PeptideBro does not recommend or calculate doses for you — it converts numbers you enter. Many compounds referenced are research chemicals not approved for human use. Consult a licensed clinician before starting, stopping, or modifying any protocol.
