Calculator

Peptide calculator

Three modes over one arithmetic core. Reconstitute a lyophilised vial, mix several solutions into one container, or resolve a multi-compound blend into its components. Every result shows its working.

Scope
Arithmetic only

For lyophilised material. Works out the concentration a given volume of diluent produces, the volume that contains a given quantity, and where that lands on the barrel.

Reconstitute calculator

01

What is in the vial?

Use the assayed content from the certificate of analysis where it differs from the label strength.

Vial capacity

02

How much diluent?

This is what sets the concentration. The quantity in the vial never changes.

mL
03

What quantity per withdrawal?

A quantity you have already decided on. This tool does not propose one.

04

How often is it drawn?

Used for one thing only: dividing whole withdrawals into days. Leave it unstated and no duration is reported.

  1. 01concentration = compound in vial ÷ diluent volume10 mg ÷ 2 mL = 5 mg/mL
  2. 02volume to draw = target quantity ÷ concentration0.25 mg ÷ 5 mg/mL = 0.05 mL
  3. 03insulin units = volume × 1000.05 mL × 100 = 5 units
  4. 04whole withdrawals = ⌊ compound in vial ÷ target quantity ⌋⌊ 10 mg ÷ 0.25 mg ⌋ = 40
  5. 05days covered = ⌊ withdrawals ÷ per week × 7 ⌋⌊ 40 ÷ 7 × 7 ⌋ = 40 days

What this tool is

This tool is educational and mathematical. It converts between quantity, volume and concentration, and it does nothing else.

It is not medical advice, not a prescription, and not a recommendation to administer anything to anybody. It does not propose a quantity, a schedule or a compound — those belong to a study design.

It is provided for lawful laboratory and research reference. Confirm any figure that will inform a decision against an independent calculation and against the certificate of analysis for the batch in hand.

Checking a figure against a batch?

The desk can confirm assayed content and water figures for the specific batch you hold, which is what the calculation should be built on.
