Read this with the answer
This is educational arithmetic on figures entered by the reader. It is not medical advice, not a dosing protocol, and not a recommendation that anything be prepared, obtained or administered.
Nothing here states what quantity is appropriate for anyone, and there is no function in it that produces an amount to administer. A question about anyone’s health belongs with a licensed clinician who can examine the person asking.
Most compounds named here are research chemicals that are not approved by the FDA for human use. An exact calculation is not an accurate measurement: what is actually in a syringe depends on the preparation and the device, neither of which this page can see.
No qualified clinical reviewer is recorded against this site, and no credential is claimed anywhere on it. Full disclaimer.
Every table here is computed, not transcribed
The figures in the concentration chart, the syringe comparison and the readability table are produced by the same code that answers the live calculators, at build time. A test checks them against the calculator cell by cell, so a table on this site cannot drift away from the tool on the next page.
That also means they can be checked. Every page states the identity it applies, in enough detail to reproduce any figure with a pocket calculator.
