Enter the peptide amount in your vial (mg), the bacteriostatic water you added (mL), and your desired dose (mg). PepKit divides dose by concentration to get the volume, and shows it as units on a U-100 insulin syringe (100 units = 1 mL). The result updates live as you type. Always verify the result against your syringe markings before injecting.
0.3 mL (30 unit), 0.5 mL (50 unit), and 1.0 mL (100 unit) U-100 insulin syringes. If a draw exceeds your selected syringe, PepKit suggests splitting it into two draws or using a larger syringe.
No, and it never will. PepKit only does math on numbers you enter and keeps records you create. Dosing decisions belong with you and your healthcare provider.
Set a protocol (dose, frequency, and time) for a medication and PepKit schedules quiet local notifications on shot days. Reminder text never includes your dose. Pro adds an optional night-before heads-up. If reminders stop, check Settings > Notifications > PepKit in iOS.
Some people split a weekly dose into two or three smaller injections spread across the week. In PepKit, set "Split dosing" in your protocol and the schedule, reminders, and per-shot dose adjust automatically.
Add a vial with its contents and mix date (or save one straight from the calculator). Shots you log subtract from it, so you always see remaining mg, doses left at your current dose, cost per dose, and days since reconstitution.
Unlimited medications and protocols, unlimited vials with cost analytics, unlimited saved calculator recipes, full weight history ranges with a 7-day moving average, and night-before reminders. Pro is $29.99/year with a 7-day free trial, or $4.99/month. The free app fully covers a single-medication routine, forever.
Go to Settings and tap "Restore purchases." Make sure you're signed into the same Apple ID you subscribed with. You can manage or cancel the subscription in your Apple ID settings.
Yes. There are no accounts and no server. Everything is stored on your device. The only network activity is Apple/RevenueCat purchase processing for the optional subscription. See our Privacy Policy.
PepKit automatically keeps a backup file on your device and offers to restore it if the database is ever damaged. You can also export a backup file from Settings (and import it on a new device) any time.
Settings > Erase all data removes everything, including the automatic backup. Uninstalling the app also removes all data.
The chart needs a compound with a half-life (built-in GLP-1s have one; custom compounds need one entered) and at least one logged shot in the last 60 days.
