Peptide Calculator Appturns vial size and bacteriostatic water into exact insulin-syringe units. Save protocols, track vial life, log every injection — built for the people who'd rather not do milligram-to-microliter math at 6am.

Three inputs.
One answer.

No more spreadsheets, scribbled napkin math, or Reddit threads from 2019. Enter what's on the vial, what you're mixing it with, and what you're trying to take. The calculator does the rest.

01 / VIAL

Type your vial size

5mg, 10mg, 15mg — whatever's on the label. The calculator handles the unit conversion (mg → mcg) so you don't have to remember whether to multiply or divide by a thousand.

02 / WATER

Pick your BAC water

2mL, 3mL, or whatever you've drawn into the vial. The volume of bacteriostatic water determines your concentration — and every dose calculation downstream.

03 / DOSE

Enter target dose

In micrograms. You get back exact units on a standard 100u insulin syringe — the only number you actually need before you draw.

Built for people who care
about getting it right.

The calculator is the headline. These are the details that make it feel like it was designed by someone who's actually used it at 6am.

01

Save your protocols

Most users run the same two or three peptides on rotation. Save a protocol — vial size, water, dose — and it's one tap to load. No re-typing every Monday.

02

Vial countdown

Track how many doses are left in each vial. The app counts down as you log injections, so you know when to reconstitute the next one before you run out mid-protocol.

03

Sanity-check ranges

If you type a dose that's outside common ranges for that peptide, the app flags it. Not advice — just a heads-up that you might have typed an extra zero.

04

Injection log

Every dose, dated and counted. Helpful when the doctor asks when you started, helpful when you can't remember if you took today's shot already.

Who's this for?

Three audiences. One math problem. The calculator doesn't care why you're solving it — it just wants you to get the right answer.

— 01 / Patients

GLP-1 users

If you're titrating semaglutide or tirzepatide and your doctor handed you a vial without a unit-converted chart, this is the tool. Type your dose, get your units.

— 02 / Lab

Researchers

For research peptides at lab scale. Reconstitution math, concentration tracking, and a clean log — without spinning up a spreadsheet for every new compound.

— 03 / Self-quantifiers

Biohackers

BPC-157, TB-500, GHK-Cu — the calculator handles whatever's in your fridge. Save protocols, count doses, stop screenshotting Reddit comments.
