Holding a vial and a syringe, second-guessing the math? PeptideBro turns "5 mg, 2 mL, 250 mcg" into "draw to 10 units", instantly, on a visual syringe. Then it keeps your whole protocol organized: every dose logged, every injection site rotated, every schedule on time. All of it private, on your device, with no account and no tracking. THE CALCULATOR Enter what's in front of you (vial amount, water added, your dose) and see: • Exact units to draw on a U-100 or U-40 insulin syringe, shown on a visual syringe • Draw volume (mL) and concentration (mcg/mL) • How many doses your vial holds Powder, pre-mixed, and two-peptide blend modes. Syringe-fit warnings when a draw is too large or too small to measure accurately. Save your usual calcs for next time.
