Research Tools
Five free calculators covering the arithmetic that comes up constantly when reading peptide research: reconstitution concentration math, first-order half-life curves, metric mass conversion, U-100 syringe volumes, and BMI categories. Each tool shows its formula and explains where its numbers can mislead. They are educational aids only — none of them evaluates whether any quantity is appropriate, and they do not constitute medical advice.
Peptide Reconstitution Calculator
Calculate concentration, syringe draw units, and dose conversions.
BMI Calculator
Research categorization based on height and weight metrics.
Half-Life Plotter
Visualize peptide decay and accumulation over time.
Unit Converter (mg ↔ mcg)
Mass conversions and "IU" context guide.
Syringe Simulator
Interactive visual guide for U-100 syringes.
How these tools fit together
Most of the arithmetic in peptide research reduces to one chain: a vial holds a mass of peptide (mg), reconstitution turns it into a concentration (mg/ml), a syringe measures a volume of that solution (ml, marked in U-100 units), and repeated doses accumulate or wash out according to the compound's elimination half-life. The calculator and syringe simulator cover the concentration-and-volume steps from opposite directions, the unit converter handles the mg/mcg/IU notation that trips up the inputs, and the half-life plotter shows what happens over time. The BMI calculator sits apart: it exists because obesity-related peptide trials define their study populations by BMI category.
For the concepts behind the math, see the dosing concept guides and the glossary. None of these pages evaluates whether a quantity is appropriate for any person or purpose — that is a clinical question covered by the medical disclaimer.
