Free peptide tools: Unit maths and scheduling that run in your browser
The short answer
Four free tools for the arithmetic and planning around a protocol: concentration and volume from a total mass, mg to mL from a label strength, exact mcg to mg, and a calendar with a printable log and phone reminders. Each one shows its working, runs entirely in your browser and never suggests an amount.
Peptide calculator
Concentration from total mass and final volume, then the volume that holds an amount, or the reverse.
mcg/mL = total mcg ÷ final mL; mL = amount ÷ concentration
Won’t Suggest an amount, or convert IU or device units.
Open the peptide calculatormg to mL calculator
Milligrams to milliliters and back, from a strength typed the way the label states it (250 mg / 5 mL, 10 mg/mL, 2% w/v).
mL = mg ÷ (mg/mL); mg = mL × (mg/mL)
Won’t Guess a strength. Without the label’s strength there is no mg-to-mL answer.
Open the mg to mL calculatormcg to mg converter
Micrograms to milligrams (and grams) and back, exact to the last digit, with a quick-reference table.
mg = mcg ÷ 1,000; mcg = mg × 1,000
Won’t Round. It moves the decimal point on your digits, so there is no floating-point error.

A start date and schedule pattern become a month calendar, a printable log and an .ics file of reminders.
Daily, every other day, 2x per week, weekly, custom days, or days on / days off, for a cycle in weeks
Won’t Fill in amounts. The log has blank columns for you to write your own.
