The peptide calculator suite
Six tools that cover ~95% of peptide math in one place. Built for biohackers, athletes, and researchers who want exact answers — not spreadsheets.
Reconstitution Calculator
Forward and reverse modes. Forward: how many units to draw. Reverse: how much BAC water to add. U-100, U-50, U-40, 1 mL syringes.
Open tool→GLP-1 Dose Escalator
Titration tables for Ozempic, Wegovy, Mounjaro, and Zepbound. Outputs weekly mg, mL, and U-100 units from a compounded vial.
Open tool→Peptide Blend Calculator
Two or more peptides reconstituted in one vial. We pick the limiting component and tell you exactly how much of each you'll receive per draw. CJC/Ipa, BPC/TB-500, and custom blends.
Open tool→Unit Converter
mcg ↔ mg ↔ mL ↔ insulin units ↔ IU. Presets for HGH, hCG, insulin, plus a custom mg/IU ratio.
Open tool→Vial Life Calculator
Total doses in a vial, run-out date, and whether your BAC water shelf-life will get there first. Six dosing-frequency presets.
Open tool→Taper Schedule Generator
Step, linear, or geometric taper for any compound. Titrate up (GLP-1, retatrutide) or ramp down (MK-677, hexarelin).
Open tool→Half-Life Decay Visualizer
Overlay multiple peptides on one timeline. See exactly what's still active in your system right now — CJC vs Ipa vs tirzepatide vs whatever you're on.
Open tool→Educational use only
This calculator is provided for research and educational purposes. Outputs are derived from the values you enter. Always verify your math and consult a licensed physician before acting on any result.
