Semaglutide mixing chart, read in three looks: find the vial row, find the water column, then read the strength. Every cell is a unit conversion. No cell is an amount to take.

Strength is in milligrams per mL: the vial divided by the water. Units are what one milligram reads as on a U-100 syringe.
5 mg vial in 1, 2 and 3 mL of water: strength 5, 2.5 and about 1.67. One milligram reads as 20, 40 and 60 units.
10 mg vial, same volumes: strength 10, 5 and about 3.33. One milligram reads as 10, 20 and 30 units.
30 mg vial, same volumes: strength 30, 15 and 10. One milligram reads as about 3.3, 6.7 and 10 units.
One rule gives every unit figure: 100 divided by the strength.
The nine cells hold only seven different strengths. Strength 5 appears twice, and so does strength 10. So vial size alone says nothing about a reading.

A unit measures liquid. One insulin label defines it: U-100 means 100 units per mL. Every chart's "1 unit is 0.01 mL" rests on that.
Of seven ranking pages read, four state the conversion. Not one cites a label.

Read across one line of the chart. Each added mL thins the mix, so the same amount fills more of the barrel. The step is fixed per vial: each extra mL adds 20 units per milligram for the 5 mg vial, 10 for the 10 mg vial, and about 3.3 for the 30 mg vial.
So a chart is arithmetic, not a label instruction. The bacteriostatic water label sets no mixing volume for any drug. It says to follow the drug maker's directions for volume.

The calculator page warns when a reading falls under about 5 units. The largest vial shows why. With 1 mL of water, one milligram is about 3.3 units, between two printed marks.
The FDA has written up what goes wrong. Its alert, marked current as of 26 July 2024, tells of a few units read as ten times that many, and of amounts up to 20 times what was meant. It points to mg, mL and units being confused.

Is the vial amount in mg? The chart is in milligrams. A vial labelled in another unit does not fit.
Does the syringe say U-100? Every unit figure here assumes it.
Is this a pen or a vial? A pre-filled pen is not mixed, so no row applies. Keeping time is left out: the top pages share no source for it. For a vial size that is not on the sheet, use the calculator that fills in any other row, a free tool from Peptides Vietnam.
