Reconstitution & dose calculator

The book explains how to reconstitute safely but never shows the arithmetic. This does. It converts a vial and a target dose into the number of units you can actually read on a U-100 insulin syringe.

Show me the arithmetic

A U-100 insulin syringe holds 100 units per millilitre. That single fact is the whole conversion: 1 unit = 0.01 mL.

  1. Concentration = vial mg ÷ water mL  →  mg per mL
  2. Volume to draw = dose mg ÷ concentration  →  mL
  3. Units = volume mL × 100
  4. In one line: units = dose(mcg) × water(mL) ÷ (vial(mg) × 10)
  5. One unit delivers = vial(mg) × 10 ÷ water(mL)  →  mcg

Worked example. A 5 mg vial with 2 mL of water is 2.5 mg/mL, i.e. 2500 mcg/mL. A 250 mcg dose is 0.1 mL, which is 10 units. Check with the one-liner: 250 × 2 ÷ (5 × 10) = 10. ✓

The water volume changes nothing about how much peptide you take. It only changes how easy that amount is to measure.

How long does it keep once mixed?

Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative, supplied in a multiple-dose container. Preservative-free sterile water has no such protection and is single-use.

The commonly applied 28-day limit for a punctured multi-dose vial is a pharmacy convention (USP <797> / CDC), not a figure printed on the manufacturer's label — the Pfizer/Hospira label carries no discard date at all. The binding limit is whichever is shorter: that 28-day container window, or how long the particular peptide stays stable in solution, which is often less.

Refrigerate at 2–8 °C once mixed, keep it dark and upright, and write the date on the vial. Bacteriostatic water is not for neonates.

About these extra tools

The cost planner, the stack check and the cycle calendar were built after the book was published. They were not part of what you paid for — they exist because readers said the book did not do the arithmetic, and they were right.

If the book was useful to you, an honest review helps the next person work out whether it suits them — including if your honest answer is that it did not.

Write a review on Amazon

Nothing on this page depends on it. Every tool here is free and stays free whether you write one or not, and this page has no way of knowing either way.

What this page is. It is a set of reference and arithmetic tools that accompany a book. It is not medical advice, it does not diagnose, and it does not tell anyone what to take. Many compounds discussed in this field — including BPC-157, TB-500, MOTS-c and retatrutide — are not approved by any regulator for human use, and in 2026 the FDA stated plainly that a “research use only” label does not change that when the seller's marketing shows human intent. Anything you decide to put in your body is a decision for you and a licensed clinician who knows your history. Nothing you type into this page is stored, saved, or transmitted — the arithmetic runs entirely in your own browser, and closing the tab erases it.
