About PeptideDosage

Almost every reconstitution calculator online is published by a company selling the compounds. They are free because they are a shop window, and several of them open a newsletter capture at the moment the answer appears.

That is not a character judgement, it is a design constraint. A calculator attached to a catalogue has reasons to present some combinations and not others, and no reason at all to tell you that a dose cannot be measured on the syringe you own. PeptideDosage sells nothing, so it has no such reasons.

It shows the working. Every calculation prints the formula, the numbers put into it and each intermediate result. None of the calculators surveyed while building this one showed any.

It tells you when a dose cannot be measured. A figure like 6.66 units is not drawable on a barrel printed in whole units. Rather than printing it to two decimals as though it were, the calculator rounds to the nearest real mark and says what that mark actually delivers.

It handles U-40. A U-40 syringe reads the same volume as two and a half times fewer units than a U-100 one, and it checks the draw against the capacity that barrel really has at that calibration rather than the U-100 figure.

It runs backwards. The diluent volume calculator starts from the number you want to draw and gives the volume of water that produces it, which is the question most people are actually asking.

It draws the syringe to scale. A coded diagram with the graduations of the barrel you selected, not a photo with a bar stretched over it.

Every formula lives in one library and every page reads from it, including the worked examples printed in the prose, so a page cannot quietly disagree with the calculator above it. That library has an automated test suite whose expected values were computed independently from the arithmetic before the code was written.

External facts, such as what is in bacteriostatic water and how insulin syringes are graduated, were taken from the FDA-approved label, the USP monograph and manufacturer specifications, then adversarially re-checked against those sources. Each page prints what it used and when it was read.

It does not tell anyone what dose to take. Every calculator here computes the figure you enter and reports what it comes to; none of them suggests what the figure should be. That is not caution about liability, it is that most of these compounds have no approved labelling and therefore no dose anyone can responsibly state.

It also does not sell anything, recommend a seller, or carry affiliate links, and it does not publish per-compound dosing guides. The disclaimer sets out the boundary in full.

Nothing you type into a calculator leaves your browser, which matters more here than on an ordinary calculator site: the privacy page explains what that does and does not cover.
