Background reading: what syringe units mean, how concentration works, research-use products, and fasting.

ConcentrationHow much peptide is in each mL of liquid. The app calculates it as mg in the vial × 1000 ÷ mL of water added (mcg per mL).
U-100 syringe unitsInsulin syringes are marked in units. On a U-100 syringe, 100 units = 1 mL, so 10 units = 0.1 mL.
Amount vs unitsAmount (mcg, mg, IU) is how much peptide. Units are how much liquid on the syringe. The vial's concentration links the two.
"Research use only"Many peptides are sold labelled for research only and aren't approved by Health Canada for human use. Quality and purity can vary between suppliers.
Certificate of analysis (COA)A lab report showing what's in a batch and how pure it is. Check that the lot number on the report matches your vial.
