Each tool answers one narrow arithmetic question. The inputs remain yours; none of the tasks selects a compound, target dose or schedule.
01
Mix optimizer
Ranks 0.25 mL mix increments by whole marks, device headroom and readable volume.
02
Reverse calculation
Solves the mix volume required to place an entered amount at a chosen tool mark.
03
Split dose
Separates a total amount from the equal per-administration amount used for draw math.
04
Fixed-ratio blend
Reports every listed component delivered by one draw from a shared entered volume.
05
IU potency
Uses an exact labeled IU total without assuming a universal mass conversion.
Worked arithmetic example
From concentration to a measurable draw
A hypothetical 5 mg vial mixed to 2 mL has a concentration of 2.5 mg/mL. An entered 250 mcg amount is 0.25 mg, so the measured volume is 0.1 mL.
Concentration5 mg ÷ 2 mL = 2.5 mg/mL
Volume0.25 mg ÷ 2.5 mg/mL = 0.1 mL
U-100 setting0.1 mL ÷ 0.01 mL = 10 units
Advanced calculator FAQs
Does the mix optimizer choose a target dose?
No. It keeps the target dose entered by the user fixed and compares water volumes only for measurement clarity and selected-device fit.
Can IU be converted to mg or mcg?
Not generically. IU potency is substance-specific. The IU tool requires the exact total potency shown on the source label and does not perform an IU-to-mass conversion.
Does fixed-ratio blend math confirm compatibility?
No. It reports arithmetic for components sharing one entered volume. It cannot establish chemical compatibility, stability or handling suitability.

Guided calculator
One choice at a time
Only the current step is active. Each choice reveals the next.
01
Read the vial label
Choose the exact compound shown on the vial. Nothing is assumed for you.
02
Match your research tool
Select the syringe, peptide pen or compatible metered spray you will use.
03
Confirm vial strength
Use the total milligrams printed on the vial—not the concentration.
04
Set the target amount per use
Enter the per-use amount and confirm whether it is measured in mcg or mg.
05
Choose liquid volume
Enter the volume used to prepare the vial. This determines the concentration.
06
Read the final setting
The completed card shows exactly what to draw, dial or dispense.
