Peptide Stack Tracker
Several compounds, several intervals, one week you can actually see.
Published by Pep AI · Peptide tracker · Updated August 2026
A stack is not several protocols side by side — it is one week with several things happening in it, and that is precisely what a list of separate reminders fails to represent. What you need to see is the day, with everything due on it.
Pep AI renders the whole stack on one calendar while keeping each compound's vials, concentrations and history entirely separate. Site rotation works across the stack rather than per compound, which matters: two compounds each rotating independently can still put every injection in the same region.
Cycles are explicit. Start dates, end dates and off periods are recorded per compound, so a stack where things start and stop at different times stays legible months later.
A stack is one week, not several lists
Everything separate where it matters, combined where it helps.
Rotation across the stack
Site rotation considers every injection you log, not each compound in isolation — so two compounds can't quietly converge on the same spot.
Doses & schedules
Daily, every-other-day, or fully custom. Get a reminder when it's time, log it in one tap, and your history builds itself.
Vials & reconstitution
Enter your vial and bacteriostatic water and Pep AI converts your dose into exact syringe units — no mixing math, no guessing.
Injection sites
Automatic site rotation so you always know where the last shot went and where the next one should go.
Estimated levels
See your estimated compound level rise and fall between doses, modelled from your schedule and published half-lives.

Frequently asked questions
How many compounds can I track at once?+
There is no limit. Each has its own schedule, vials and history, and they render together on one calendar.
Does site rotation work across multiple compounds?+
Yes, and it needs to. Two compounds each rotating on their own can still land in the same region repeatedly. Pep AI rotates across every injection you log rather than per compound.
Does Pep AI give medical advice?+
No. Pep AI is a tracking and organisation tool, not a medical device. It does not recommend compounds, doses or schedules, and Pep Bot declines dosing questions. What to take stays between you and a qualified clinician.
