Peptide Research Calculators
8 professional tools covering every stage of a peptide protocol — from reconstitution to full cycle cost planning. Free, real-time, no sign-up.
Reconstitution Calculator
Calculate peptide concentration and exact draw volumes from vial size and BAC water. Includes dosing table and BAC water optimizer.
Injection Volume Calculator
Convert dose and concentration to the exact mL and syringe unit mark. U-100 and U-40 support with precision warnings.
Body Weight Calculator
Calculate your personalised total dose from a per-kilogram research protocol with kg / lbs conversion.
Vial Duration Calculator
Find how many days your reconstituted vial lasts and flag any 28-day expiry window issues.
Cost Calculator
Calculate cost per dose, weekly spend, monthly budget, and full cycle cost for any peptide protocol.
GLP-1 Titration Planner
Complete semaglutide or tirzepatide titration schedule with weekly doses, reconstitution instructions, and vial planning.
Protocol Builder
Build a full multi-peptide weekly injection schedule with vial requirements for your cycle length.
Peptide Reference Table
Searchable dosing reference for 23 peptides: dose ranges, frequency, route, and research notes.
Retatrutide Calculator
Calculate retatrutide reconstitution concentration, exact draw volume, and doses per vial for your weekly protocol.
Ozempic (Semaglutide) Calculator
Calculate semaglutide reconstitution concentration, draw volume, and doses per vial for every titration phase from 0.25 mg to 2 mg.
Tirzepatide Calculator
Six-phase tirzepatide reconstitution and dosing calculator — 2.5 mg to 15 mg/week with exact draw volumes for every vial size.
BPC-157 Calculator
BPC-157 reconstitution calculator with injection frequency selector — once daily, twice daily, EOD, or weekly dosing.
TB-500 Calculator
TB-500 loading and maintenance phase calculator — dose per injection, vial size, BAC water, and syringe draw volume.
BAC Water Optimizer
Reverse-calculate the ideal bacteriostatic water volume to achieve a target draw size for any dose and vial combination.
Peptide Half-Life Tracker
Track how much peptide remains active after your injection — see time to 50%, time to clear, and a visual decay timeline for 22 compounds.
Peptide Stack Compatibility
Check compatibility between 2–3 peptides — synergistic pairs, caution combinations, and mechanism notes from 20 documented stacks.
Injection Schedule Calendar
Build your weekly peptide injection schedule — add compounds to each day, track doses and routes, then print your protocol card.
About these calculators
All calculators use verified pharmacological formulas. The reconstitution and injection volume tools support both U-100 and U-40 syringes and flag draws that are too small to measure accurately. The vial duration tool enforces the 28-day reconstituted peptide expiry limit. GLP-1 titration schedules are based on the FDA-approved Ozempic and Mounjaro prescribing information.
