Peptide blend calculator
A blend is several peptides in one vial. Enter the components and how much you draw, and this works out the dose of each peptide in that single injection, so you know exactly what you're taking.

If your vial isn’t on that list
You just defined a blend. Lirea can remember it.
This page answers one injection and then forgets, and you are back here the next time the numbers change. In the app you enter that composition once, and every dose after it is split automatically: milligrams per peptide per injection, running totals that count a shared peptide once rather than twice, and a separate curve for each component, because a blend has no half-life of its own.
The named blends are free at full depth, and so is entering the exact milligrams your own vial holds. Defining one that isn’t in the library is Pro.

Blends share ingredients: BPC-157 and TB-500 show up in Wolverine, GLOW, and KLOW alike. If you also run one of those peptides on its own, it's easy to lose track of how much you're really taking. Seeing the per-peptide dose is the first step; the app then keeps the running totals across everything so nothing gets double-counted.
