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.
- Concentration = vial mg ÷ water mL → mg per mL
- Volume to draw = dose mg ÷ concentration → mL
- Units = volume mL × 100
- In one line: units = dose(mcg) × water(mL) ÷ (vial(mg) × 10)
- 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.
Reference table — units per dose at common dilutions
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.
Cost & supply added after publication
What a protocol actually costs per dose, how many vials it needs, and — the part almost nobody works out — how much of what you buy you will throw away because the vial expires before you finish it.
Cost per dose, and what you will waste
Which supplier is actually cheaper
Vial sizes differ, so sticker prices are not comparable. This puts both on the same footing: cost per milligram, and cost per your dose.
Cycle calendar
The book argues for on/off periodisation but never lays one out. Set the pattern and see the whole run at once.
Stack check added after publication
Tick everything you are taking at once. This looks for the three things that quietly go wrong in a stack: taking the same compound twice without realising, piling up compounds that do the same job, and the handful of interactions that genuinely matter.
Where to start
Pick what you are actually trying to change. This will not tell you what to take — it tells you which families are studied for that goal, how solid the evidence is, what legal status each has, and the specific questions worth putting to a prescriber.
Book decoder
Several stack entries in the book use generic placeholder names — a category written where a product name should be. If you went looking for one of these and could not find it to buy, that is why. Here is what each one refers to, and what is actually real.
What changed since the book was written
The manuscript closed in mid-2025. Four things have moved since, and they are the four things readers ask about most.
Companion files
Reference documents that accompany the book — protocol libraries, reference lists and worksheets. Two of them were written after publication and answer the questions readers asked most.
Written after publication
Reconstitution & Dosing — the arithmetic the book leaves out: milligrams to millilitres to units on a U-100 syringe, full reference tables, choosing your dilution, blends, storage and beyond-use dating. 6 pages, PDF.
What Changed — the incretin drugs, retatrutide, KLOW, the current legal position on “research use only”, and corrections to six placeholder names used in the book’s stack sections. 4 pages, PDF.
The full folder
The nine original documents — the stack and protocol libraries, the peptide reference list, the roadmap, the nutrition and supplier guides, and the methylene blue and exosome chapters — are in the same folder the QR code in the book opens.
If the folder will not open on your phone, try a desktop browser, or tap the three-dot menu and choose “Open in browser”. The two documents above are linked directly here so you do not need the folder to read them.
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.
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.
