[Free dosage calculator](https://peptidemind.com/peptide-dosage-calculator/blend) built specifically for peptide blends. Sharing it here in case it's useful.

**Why it exists**

Blend vials make the math tricky. A blend isn't one peptide, it's two or more compounds sharing the same solution in fixed ratios. If the anchor dose is off, every other compound in that draw is off too. The tool handles that calculation automatically.

**How it works**

Users pick a blend from a pre-loaded list with known compound ratios, or build a custom mix. Each compound shows its proportion of the total vial content so the makeup is clear before any calculation runs.

Next is reconstitution volume, the amount of bacteriostatic water added in mL. That sets the concentration of the entire blend. The ratios stay constant no matter how much water goes in, which is the defining feature of a blend.

Final step is selecting an anchor compound, the one being dosed by. The calculator works backward from that target dose to determine the draw volume, then shows the resulting dose of every other compound delivered in the same injection.

**What a peptide blend actually is**

For anyone newer to this: a peptide blend is a single vial containing two or more peptides in a fixed ratio, reconstituted together in bacteriostatic water. Because the compounds share one solution, it delivers a precise dose of each one at the same time. No drawing from multiple vials. Most blends pair peptides with complementary mechanisms so a protocol collapses into one daily use.

The tool is free, browser-based, and doesn't require an account.
