01How it works

You run the protocol. PepCore keeps the record.

Add the compounds, amounts and schedule you already follow. PepCore reminds you when an entry is due, shows which injection site you used last so you can rotate, and keeps every entry on a calendar you can look back through.

It records what you enter — it doesn't work out, suggest or check any amount. Everything stays on your iPhone, with no account and no sign-in.

02What PepCore is

A logbook for a protocol you are already running.

An iPhone app that keeps the schedule, the reminders and the log in one place. It records the compounds, amounts and schedules you choose — it does not choose them.

The PepCore Today screen: how much of today's protocol is logged, a streak, active peptides and the day's activity.
Today — what's due, taken, missedSample data
The PepCore injection-site map: a body map showing which sites were used recently and when each was last used.
Injection sites — which one you used lastSample data
The PepCore progress screen: streak, entries logged this month, a weekly chart and the most-used site.

PepCore for iPhone is a subscription app — $39.99/year or $6.99/month, each with a 7-day free trial.

03What it does

Built for someone running an actual stack.

Not a reminder app with an icon on it. One subscription unlocks all of it, grouped the way the work actually happens.

Plan

Today view
Due, taken, skipped and overdue in one screen, with a follow-up reminder if you miss one.
Schedules & reminders
Days on, days off or weekday schedules that you set, with a notification when an entry is due.

Rotate

Injection-site map
A body map with rotation history, so you can see which site you used last.
Cycle tracking
Keep track of on and off cycles for each protocol you run.

Log

Calendar & history
Every entry you've logged, on a calendar you can look back through.
Blood work & body metrics
Record blood work, weight and body measurements alongside your protocol.

Keep

Journal
Your own notes, kept next to the log they belong to.
Export & backup
Export your log as a PDF or text report, or back it all up to a file you move to a new iPhone yourself.

04Privacy

No account. No sign-in. Nothing for us to attach a log to.

Your protocols, doses and logs live on your device, encrypted at rest, with an optional Face ID lock. There is no sign-in, so there is no server-side record of you.

Moving to a new iPhone is a backup file you AirDrop across, and that file never passes through a server of ours. Exporting your data is free whether you are subscribed or not — your log is never held hostage.

One optional feature leaves the device, and only when you ask it to: the AI Coach sends what you submit through our proxy to the AI provider. The privacy policy sets out what is sent, where it goes and what is kept.

PepCore's App Store privacy label is Data Not Linked to You: Health, Photos or Videos, Other User Content and a device identifier, each for App Functionality, none of it linked to you, no tracking. No analytics, no third-party SDKs. This website makes no third-party request of any kind — no fonts, no CDN, no tag.

05Pricing

One subscription. 7-day free trial.

PepCore is a subscription app. One subscription unlocks the whole thing: no ad tier, no upsell inside it. Cancel in Settings before the trial ends and you are not charged.

Yearly

$39.99 / year

7 days free, then $39.99/year. That is $3.33 a month, 52% less than paying monthly.

  • The whole app: unlimited peptides, dose reminders, the injection-site map, schedules, the calendar and history, cycle tracking, the journal, logs, Face ID lock and backup
  • Blood work and body-metric logs, kept alongside your protocol
  • PDF and text reports of your protocol and logs

Exporting your data is always free, subscribed or not. Your log is never held hostage.

Monthly

$6.99 / month

7 days free, then $6.99/month.

  • Everything in Yearly — the same app, on a shorter commitment
  • Cancel any time in Settings

That works out to $83.88 a year. If you plan to stay, Yearly buys the same thing for less.

Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it's cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours of the end of that period. Any unused portion of a free trial is forfeited when you buy a subscription. Manage or cancel yours in Settings → your name → Subscriptions. See our Privacy Policy and Terms of Use.

06Questions

Common questions

What does PepCore do?

It's a personal log for a protocol you already run. You enter your own compounds, amounts and schedule; PepCore reminds you when an entry is due, shows which injection site you used last, and keeps a calendar of everything you've logged. It does not work out, suggest or check any amount.

Is the iPhone app free?

PepCore for iPhone is a subscription app: $39.99 a year or $6.99 a month, each with a 7-day free trial. One subscription unlocks everything: protocols, dose reminders, the injection-site map, the calendar and history, cycle tracking, the journal, blood work and body-metric logs, and backup. There is no ad-supported version and we do not sell your data.

What happens when the free trial ends?

If you don't cancel, it converts to a paid subscription automatically and Apple charges the card on your Apple Account. If you cancel any time before the last 24 hours of the trial, you're not charged. Cancelling is in Settings → your name → Subscriptions, and it takes about four taps. Your data stays on your phone either way.

Is my data sent anywhere?

PepCore stores everything on your iPhone, encrypted at rest, with an optional Face ID lock. There is no account, no analytics and no tracking. The one exception is the optional AI Coach: if you use it, whatever you submit is sent through our proxy to the AI provider, and we do not store it. Our privacy policy sets that out in full.

Is there an Android version?

Not yet — PepCore is iPhone-only for now.

Does PepCore give dosing advice?

No, and it never will. It's a log. It doesn't work out, recommend or check compounds, amounts, schedules or combinations. Those are decisions for you and a qualified healthcare professional.
