The calculators
Eight tools. Each takes different inputs and answers a different question.
Educational arithmetic only. Not medical advice and not a dosing protocol.
- Peptide calculator
Vial strength and diluent to a concentration, a draw volume and a syringe reading.
- Dose and volume
Amount to volume, or volume to amount, at a concentration already known.
- Diluent for a target concentration
Solves the solution volume rather than the strength.
- Syringe units
One volume on U-100, U-50 and U-40, side by side.
- Unit converter
Mass, volume, international units at a stated potency, and molar amount.
- Blended vial
Two compounds, one shared volume, both reported in every draw.
- Dilution
C1V1 = C2V2 for a solution that is already mixed.
- Half-life curve
First-order elimination from a half-life you supply.
Read this with the answer
This is educational arithmetic on figures entered by the reader. It is not medical advice, not a dosing protocol, and not a recommendation that anything be prepared, obtained or administered.
Nothing here states what quantity is appropriate for anyone, and there is no function in it that produces an amount to administer. A question about anyone’s health belongs with a licensed clinician who can examine the person asking.
Most compounds named here are research chemicals that are not approved by the FDA for human use. An exact calculation is not an accurate measurement: what is actually in a syringe depends on the preparation and the device, neither of which this page can see.
No qualified clinical reviewer is recorded against this site, and no credential is claimed anywhere on it. Full disclaimer.
Why eight and not eighty
"Peptide calculator", "peptide dosage calculator", "peptide calculator dose" and "peptide dosing calculator" are four ways of asking for the same arithmetic, and they get one page between them rather than four near-identical ones. A page earns its place here by taking different inputs or producing a different output, not by matching a different phrasing.
All eight share one calculation engine, so they cannot disagree with each other. The concentration the blend calculator computes and the concentration the main calculator computes come from the same function, tested once.
