What We Do
Making Peptide Math Accessible
Pepper Conversion was built around a single frustration: peptide dosing math isn't hard, but it's surprisingly easy to get wrong. You have a vial with a milligram amount, a target dose in micrograms, and a syringe calibrated in units. Translating between those three things requires knowing the right formula — and knowing where errors hide.
This site gives you a free calculator that handles that math instantly. Enter your vial amount, how much bacteriostatic water you used, and your target dose. You get back your draw volume in mL and the exact unit mark on a U-100 insulin syringe. No guessing, no manual arithmetic, no unit conversion errors.
Beyond the calculator, we publish plain-language educational guides on reconstitution, storage, syringe types, BAC water, and compound-specific considerations — everything that helps you understand what you're doing, not just the number to draw to.
Our mission: make peptide dosing math understandable for everyone — not a medical service, just a clear educational reference that works for you when you need it.
Who This Is For
Built for People Who Want to Understand the Math
Pepper Conversion is designed for anyone who wants to understand the arithmetic behind peptide dosing — patients working with compounding pharmacies, researchers, or anyone trying to make sense of a reconstitution protocol they've been given.
This is an educational reference tool, not a prescribing service. We don't tell you what to take, how often, or at what dose. That guidance belongs to your licensed clinician and pharmacist. What we do is help you verify the math — so that when your doctor says "take 250mcg twice weekly," you know exactly what that means in terms of mL and syringe markings.
The calculator works for all common peptide compounds: Semaglutide, Tirzepatide, Retatrutide, BPC-157, TB-500, NAD+, GHK-Cu, and any other compound you need to dose by weight.
