Themath,explained

How reconstitution math converts values you enter into concentration, volume, and U-100 units. Published formulas. No protocol. No recommendation. No legal determination.

Research-use mathematical conversion only. Not for human consumption. This page does not recommend a compound or amount, does not instruct use, and is not medical or legal advice. Example numbers are illustrations. Verify every value independently. Read the legal notice.

Clear before use

What this is. What this is not.

This is
  • A free arithmetic converter. You enter values. It returns concentration, volume, and U-100 units.
  • Published formulas. The math is visible so you can check it.
  • Research-use and educational content. Mathematical conversion only.
This is not
  • Medical advice, diagnosis, treatment, or a substitute for a licensed clinician or pharmacist.
  • A protocol, prescription, or recommendation of any compound, amount, or schedule.
  • A determination that any possession, reconstitution, or use is lawful where you are.
User-entered values

What you type in

The conversion does not invent a fourth value. It does not know what is in the vial. It converts the three numbers you provide.

01
Peptide (mg in vial)

The milligrams printed on the vial you type in. Total mass in the vessel — not a prescribed amount.

02
Diluent volume (mL)

Milliliters of diluent you type in. More liquid lowers concentration. Same entered quantity, larger converted volume.

03
Entered quantity (mcg)

The micrograms you type in. The conversion does not choose, suggest, or validate this number.

04
U-100 scale capacity

1 mL, 0.5 mL, or 0.3 mL. A ceiling check on converted volume. It does not change the conversion: 100 units = 1 mL.

Formula & validation

How the math runs

Illustrative arithmetic

Same mass. Same entered mcg. Move the liquid.

These figures are default inputs for the illustration, used here so the conversion is visible. They are not recommended amounts. Diluent volume is the lever: it does not change the entered quantity. It changes the milliliters that contain that quantity.

Vial (typed)

Quantity (typed)

Scale
1 mL = 100 u
2.0 mL
1 mL · higher concentration3 mL · larger volume
5 × 1000 ÷ 2.0 = 2500 mcg/mL
U-100 volume scale · 100 units = 1 mL
10 u
U-100 volume scale — 100 units = 1 mL
