Peptide mg to Insulin Units: Conversion Charts
The base rule
A U-100 syringe holds 1 mL at 100 units. Units = (target mg ÷ concentration mg/mL) × 100.
Reference chart
| Concentration | 250 mcg | 500 mcg | 1 mg | 2 mg | 5 mg |
|---|---|---|---|---|---|
| 1 mg/mL | 25 u | 50 u | 100 u | — | — |
| 2.5 mg/mL | 10 u | 20 u | 40 u | 80 u | — |
| 5 mg/mL | 5 u | 10 u | 20 u | 40 u | 100 u |
| 10 mg/mL | 2.5 u | 5 u | 10 u | 20 u | 50 u |
Choosing a diluent volume
Pick the volume that lands your target amount between 10 and 50 units — that range is where a U-100 syringe is most accurate.
How PX1 documents every lot
Every PX1 lot ships with HPLC purity, LC-MS identity, residual solvent, moisture (Karl Fischer), sterility and endotoxin data. Lot documentation is published at /purity-reports, /endotoxin-reports and /coa. Manufacturing, purification, lyophilization and vial fill happen in U.S. facilities — see /manufacturing-process.
Research use only. PX1 Research supplies compounds for laboratory and in-vitro research. Nothing here is medical advice, a dosing recommendation, or an offer for human or veterinary use. Figures cited are reported from published laboratory literature.
