Published by Pep AI · Peptide tracker · Updated August 2026
The growth hormone peptides are the most stack-prone category there is: releasing factors and secretagogues run together, often on different intervals, out of vials with different concentrations. It is the exact shape of protocol that defeats a spreadsheet.
Pep AI holds each compound separately — its own schedule, its own vials, its own history — while showing the whole week on one calendar. Level projections use each compound's published half-life, which matters here more than elsewhere because the range within this category spans minutes to a week.
Cycles get explicit start and end dates, including the off period, which is the part almost nobody records and the part that tells you whether anything you noticed persisted.
Built for the stack, not one compound
The GH category is where half-lives differ most. Pep AI models each one separately.
Per-compound half-lives
Level projections use each compound's own published figures, so a minutes-long secretagogue and a week-long releasing factor don't share one curve.
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
Which growth hormone peptides can I track?+
Any of them — the compound list covers the secretagogue and releasing-factor families, and you can add a custom compound with your own half-life if something is missing.
Does it handle compounds with very different half-lives in one stack?+
Yes. Each compound's level projection uses its own published half-life and time-to-peak, so a compound that clears in minutes and one that lasts a week are modelled independently.
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.
