Peptide Lab: Dosage Calculator

Peptide Lab is a peptide dosage calculator and injection tracker for research and educational use. Reconstitute a vial, calculate the exact volume to draw, and keep an organised log, in one private app.

DOSAGE AND RECONSTITUTION CALCULATOR
Enter vial strength, bacteriostatic water and the amount you want. Peptide Lab gives you the volume to draw and the number of units on an insulin syringe, instantly. No manual maths, no spreadsheet.

WORKS FOR THE COMPOUNDS YOU TRACK
BPC-157, TB-500, GHK-Cu, semaglutide, tirzepatide, retatrutide, CJC-1295, ipamorelin, IGF-1 LR3, and any other peptide you add yourself, including blends.

INJECTION LOG WITH BODY MAP
Record each administration with amount, date and site on an interactive body map. Rotate sites and see your whole history at a glance.

VIAL AND EXPIRY MANAGEMENT
Track unlimited peptides and vials with their reconstitution details, and get an alert before a vial lapses.

IMPORT YOUR SPREADSHEET
