Personal peptide vial, reconstitution arithmetic, and dose logging for iOS

Ligand organizes your own vial details, reconstitution arithmetic, dose logs, and schedules. You supply the values; the app calculates from those inputs and keeps the record.

What Ligand does

Vial and reconstitution arithmetic

Enter your own vial amount, diluent volume, and target amount. Ligand works the arithmetic from the values you supply.

Vial tracking

Keep the vial details you enter together with their related records.

Dose logging

Log your entries and review your recorded history in one place.

Scheduling

Create schedules for the vial records you choose to organize.

iCloud sync for Pro users

iCloud sync is a Pro feature. For users with access, it is enabled by default and can be disabled in iOS Settings. Data syncs through your private Apple iCloud account.

Related NAD+ arithmetic tool

For transparent web-based arithmetic, use the NAD+ reconstitution calculator. You still supply every value.

Pro Peptide Assistant, powered by Anthropic Claude

Ligand Pro includes a Peptide Assistant for general reference questions about peptide kinetics and commonly reported protocols.

Know its limits. Assistant output may be incomplete, wrong, or outdated. It does not recommend or prescribe any substance or dose, it is not a dose recommendation, and it is not a substitute for a licensed clinician. Do not use it to make a health, substance, or dose decision.
