Never wonder if you already took it

A free iOS app for tracking a complicated medication schedule.

Download on the App Store Free. No subscription. No account required to try it.

What it does

Reminders that know your schedule

Weekly, every other day, multiple times a day, or cycled on and off. Mark a dose taken straight from the lock screen without opening the app.

Stop doing the maths every time

Tell it your vial size and how much bacteriostatic water you added. It shows your dose in syringe units everywhere, so you never work it out twice.

A report your doctor can actually read

Everything you have logged, exported as a clean PDF in a couple of seconds. Better than trying to remember at an appointment.

Written down honestly

Every compound in the library carries an evidence label — approved, in trials, early human data, animal data only, or anecdotal. Most are not approved for human use, and the app says so.

The maths people get wrong

A U-100 syringe is 100 units per mL

Not 1000. A 5 mg vial in 2 mL of bacteriostatic water is 2.5 mg/mL, so a 0.5 mg dose is 0.2 mL:

0.5 mg → 20 units The mistake is always in the same direction — ten times too much. Peptly does this for you, and warns you when a result is too small to draw or larger than a full syringe.

Peptly is an educational and tracking tool. It does not provide medical advice, diagnosis or treatment, and does not sell any compound. Always consult a licensed healthcare provider. You must be 18 or older to use it.
