Why we built mcgcalc

Peptide reconstitution math is straightforward, but getting it wrong has real consequences. Miscalculating a concentration or drawing the wrong number of units can mean the difference between an effective protocol and a wasted vial — or worse.

We built mcgcalc because the existing tools were either cluttered with ads, required account sign-ups, or sent your data to remote servers. We wanted something simple: enter your values, get accurate results, move on.

How it works

Every calculation runs entirely in your browser. No server requests, no databases, no tracking. When you save a calculation, it stays in your browser's local storage — we never see it.

The suite includes five tools: a Dosage Calculator for syringe unit calculations, a Reverse Calculator to determine BAC water volume, an Intranasal Calculator for nasal spray formulations, an Order Calculator to plan vial quantities across a protocol, and a Unit Converter for quick conversions between mL, mg, mcg, and µL.

Our principles

  • Privacy first. We don't collect personal data. No analytics cookies, no fingerprinting. Core calculators are always free.
  • Accuracy matters. Calculations are validated against standard reconstitution formulas. Results update in real time as you type.
  • Free, no strings. No premium tiers, no paywalls, no "sign up to unlock." Every feature is available to everyone.
  • For research purposes. This tool is intended for educational and informational use. Always consult a qualified healthcare professional for medical decisions.
