Concentration
Concentration tells you how much compound is present in each millilitre. Divide the amount in the vial by the final volume reported on that page.
The result depends on the final volume and the specific formulation described on the page.
U-100 units
On a U-100 syringe, 100 units equal 1 mL, so one unit equals 0.01 mL. To find the micrograms per unit, multiply the concentration in mg/mL by 10.
Syringe capacity and graduations vary. The calculator also shows the nearest graduation for 30, 50 and 100 unit syringes.
Storage and formulation
Storage instructions depend on the product, its formulation and whether it has been prepared. Guidance for one compound cannot automatically be applied to every vial.
For approved medicines, follow the official product information. For research compounds, evaluate the quality and relevance of each source separately.
Before interpreting a page
- Check that the compound name and vial strength match the source you are reading.
- Separate observed research data from an editorial worked reconstitution example.
- Check the route of administration, formulation and device behind each value.
- Read the evidence and the original publication before drawing conclusions.
