Peptide dosing chart
One sheet for the vial on your shelf. Pick the vial size and how much water you add, and the chart lists the units for every common dose from 50 mcg to 5 mg. Print it and keep it with the vial.

Rows over 100 units will not fit a 1 mL syringe at this concentration; use less water. Rows under 3 units are hard to measure; use more water. The dose itself comes from your prescriber and the product label.

Find your dose in the left column and read across. The next column is the number of units to draw on a U-100 insulin syringe at this concentration, then the same draw in mL, then how many of those doses the whole vial holds. With a 5 mg vial and 2 mL of water, the 250 mcg row reads 10 units, 0.1 mL and 20 doses. That row is an example of the math, and the chart lists many doses so that it works for any vial. It does not know which peptide you have, and it does not suggest a dose.
What do the starred and faded rows mean?
A star means the dose needs more than 100 units at this concentration, which is more than a 1 mL syringe holds. A faded row is hard to measure or will not fit. Rows like these are a prompt to check the water amount with your pharmacy instructions.
Which water amount should you print?
The one your pharmacy label gives. If you were given a range, try each option here and look at your own row. Draws of about 5 to 50 units are easy to read, and a one-unit reading error matters less there than it does at 3 units. The reconstitution calculator explains the reasoning with a worked example.
Label the vial to match
Write three things on the vial the day you mix it: the date, the water added and the resulting concentration in mg/mL. Then the chart and the vial always agree. A new vial with a different strength or water amount needs a new sheet, so throw the old one away to keep it from being used by mistake. The reconstitution guide covers the rest of the technique, and the dose tracker is the sheet to keep alongside this one.
Where do doses come from?
For FDA-approved drugs, the label. For investigational drugs, the published trials. For peptides with neither, there is no human dosing standard, and each profile in the Peptides A–Z says so plainly. The chart will convert any number you give it, so the number itself has to come from your prescriber.
