How does the calculator convert a peptide dose into syringe units?
It first calculates the concentration from the peptide mass and the amount of solution added, then converts the selected dose into the corresponding liquid volume and U-100 syringe units.
How much solution should be added to a vial?
There is no single universal volume. Changing the amount of solution changes the concentration, so the same peptide dose can correspond to a different number of syringe units. Use the actual amount added in the calculator.
What do “units” mean on a U-100 syringe?
They are a volume scale: 100 units equals 1 mL, 10 units equals 0.1 mL, and 1 unit equals 0.01 mL.
Are U-100 units the same on 30-unit, 50-unit, and 100-unit syringes?
Yes. The unit volume is the same; the syringe sizes differ only in total capacity.
What is a COA?
A Certificate of Analysis is a laboratory report that may include tested properties such as identity, purity, or measured mass. If you have a tested mass, entering that value can make the concentration calculation more precise.
Why use the measured peptide mass instead of only the vial label?
The labeled amount is typically a nominal value. If a reliable laboratory report provides a measured mass, the calculator can use that exact number rather than the rounded label amount.
What is bacteriostatic water?
It is sterile water containing a bacteriostatic preservative. Whether it is appropriate for a specific product depends on that product's formulation and instructions.
How should a reconstituted peptide be stored?
Storage and stability vary by compound and formulation. Follow the manufacturer, pharmacy, or qualified clinician's instructions rather than assuming a single storage period applies to every peptide.
What does half-life mean?
Half-life is the time required for the amount of a substance in the body to fall to roughly half its previous level. It is a pharmacokinetic property and does not by itself determine an appropriate dosing schedule.
