## What is Ligand · Peptide Dose Tracker?

Ligand is a fast, private calculator and log for reconstituted peptides — built to show its work, not to tell you what to take.

RECONSTITUTION & DOSE MATH YOU CAN CHECK
Enter your vial mass, BAC water, and target dose — in mg or mcg, your choice — and Ligand lays out the concentration, the corresponding syringe volume, and the exact syringe units, with every step of the working shown. See the exact result and where it lands on a whole syringe mark.

SAVE EVERY CALCULATION
Save any calculation as a checkable record: the inputs you entered, the full derivation, and the result, frozen exactly as they were. Reopen it anytime, use it as the start of a new one, or share the whole working as plain text.

FREE TO TRY — NO ACCOUNT
The calculator, your saved calculations, and your log are free. No sign-up, no account, no paywall before you can check a number.

A PRIVATE LOG
Track your vials and your own schedule. Your data stays on your device — it's yours.

PRO (optional)
• Unlimited vials
• Export & back up your records — CSV + JSON
• Peptide Assistant — brief answers on kinetics and mechanism, with source links
Available monthly, yearly, or as a one-time Lifetime purchase.

Ligand does the math and keeps your record. It does not provide medical advice, diagnose, or recommend a dose. Always consult a qualified healthcare provider before any decision about a medication or compound.
