Peptain: Peptide Dose Tracker

Peptain: Peptide Dose Tracker

Peptain holds the whole picture of a protocol: what you took, when, where it went, and what it is still doing right now.

It is built for the way a protocol actually runs. Doses move. Cycles turn over. A compound gets added in week three and dropped in week nine. Peptain keeps up with that instead of asking you to start a fresh log every time something changes.


01 / WHICH ONE AM I ON TODAY?

Open the app and today is already answered. Every compound you run sits on one screen with its dose, its time, and the day it falls on inside its cycle. Logging takes two taps, and your vial counts itself down as you go, so the number on screen is the number left in the glass.


02 / IS IT STILL IN MY SYSTEM?

Peptain takes the doses you have already logged, pairs each one with that compound's half-life, and draws your estimated levels as a living curve: where you peak, where you trough, where an ordinary day sits. Move between a twelve hour, daily, weekly and monthly view and a titration becomes something you can see before you feel it.


03 / WHERE DID THE LAST ONE GO?

The site map remembers for you. Every place you have injected is shaded by how recently you used it, and the site that has rested longest is the one Peptain points at next. Rotation is tracked across all your compounds at once, so nothing quietly piles up in the same spot.


04 / WHAT WEEK OF THE CYCLE IS THIS?

Build a cycle once, with its on weeks and its off weeks, and it carries itself forward. The calendar shows the phase you are in, the day it flips, and how overlapping compounds line up against each other. Schedules stack into named routines with their own frequencies, so a morning set and an evening set stay separate without being managed separately.


05 / WHAT AM I ACTUALLY TAKING?

A reference library of 90+ peptides, GLP-1 medications and supplements travels with you and works offline. Half-lives, typical ranges, mechanisms, categories and citations, readable on a plane or in a waiting room with no signal.


06 / DID ANY OF IT WORK?

Weight, water, sleep, mood, workouts, bloodwork, side effects and basic nutrition land on the same day view as the doses themselves. Peptain reads across them and writes a short daily note about what is moving with what. The more days you keep, the more specific that note becomes.


THE SMALL THINGS

Reminders that fire per compound, not per app. Goals and streaks that reward showing up rather than perfection. Named stacks. Custom compounds for when yours is not in the library. Units that follow you everywhere. A today view you can strip back to only the things you care about.


PRIVATE BY DEFAULT

Peptain runs fully as a guest, with your data on your device and no account at all. Sign in only if you want a backup across devices. Nothing sold, nothing advertised.


WHAT THIS IS, AND IS NOT

Peptain is a personal tracking tool, not a medical device. It never suggests a compound, a dose or a schedule: you enter what your own clinician prescribed, and Peptain keeps the record. It does not diagnose, treat or give medical advice. Talk to your doctor before starting, changing or stopping anything.
