Petri Peptides

Semaglutide calculator

Pick your semaglutide vial, add water, and the syringe reading appears — ladder included, math not required.

Here is the weekly routine in one breath: start at 250 micrograms, hold each dose for four weeks, then step up — 500, 1000, 1700, and finally 2400 micrograms from week twenty-one. The page turns that schedule into a table and pairs it with draws computed for your exact vial and diluent.

A starter combo that works: the five milligram vial with two millilitres of bacteriostatic water, which makes week one a ten-unit draw. Snap over to the Schedule tab and the whole titration prints out with dates — handy taped inside the lab notebook door.
