What if my peptide dose is under 2 units?
A dose under 2 units is mathematically possible, but it is hard to measure accurately on a standard U-100 insulin syringe. The usual fix is not to eyeball between ticks, but to make the solution more diluted so the same peptide dose draws to more units.
Why it happens
Tiny draws happen when the vial is concentrated relative to the dose. Example: a large mg vial mixed with a small amount of BAC water, then used for a small mcg dose.
What changes the unit number
- More BAC water increases the unit draw for the same dose.
- Less BAC water decreases the unit draw.
- The dose amount and total vial amount stay the same.
What not to do
Do not guess at a fraction of a tick mark if accuracy matters. Re-run the math with a different BAC water amount and confirm the label units first.
