Changelog
Changes you could notice, with dates: presets re-checked against their labels, label changes, fixes to reported problems, and new medications or pages.
1.1 · 2026-09-05
- Four mixing tools built from the FDA labels: a diluent passport for each supported vial presentation, three clocks for the dates a mixed vial and its water vial run on, a syringe lab that shows where a volume lands on each barrel, and a bacteriostatic water page that checks whether the four labels agree.
- Twenty-four more conversion question pages for tirzepatide, semaglutide and insulin, thirty in all.
1.0 · 2026-09-05
- First public release.
- Calculator for powder and liquid vials in mg, mcg or units, with the draw shown on U-100 1 mL, 0.5 mL and 0.3 mL syringes and the U-40 veterinary syringe.
- Label presets for tirzepatide (Zepbound vials), U-100 and U-40 insulin, somatropin (Serostim, Zomacton, Omnitrope), HCG (Pregnyl, Novarel), mecasermin, tesamorelin, enfuvirtide, teduglutide, setmelanotide, octreotide, metreleptin, pegvisomant, vosoritide, elamipretide, glucagon emergency kits and calcitonin, each read from the FDA label on 2026-09-04 and linked on the sources page.
- No semaglutide preset, because no FDA-approved semaglutide vial exists. The semaglutide page takes the concentration from your own pharmacy label.
- Six conversion question pages and three printable charts.
