Supplement, nootropic & peptide stack tracker
Run your stack like an experiment, not a spreadsheet.
Log every dose, schedule, and cycle across supplements, nootropics, peptides, and HRT — then layer on AI interaction analysis, pharmacokinetic serum-level curves, and WHOOP correlation. Built for people who actually titrate.
Free to start. No card. Your stack data is private and exportable — we don't sell it.
See it
Your protocol, logged and analyzed — in your pocket.
What it does
Everything a spreadsheet pretends to do — done properly.
Log doses, not guesses
Daily, cycling, or specific-day schedules across AM / midday / PM slots. Mark-as-taken in two taps. Your protocol, exactly as you actually run it — no more stale spreadsheet rows.
Claude reads your whole stack
AI surfaces interactions, redundancies, synergies, and timing conflicts across everything you take — supplements, nootropics, peptides, HRT. Informational, never prescriptive.
See the curve, not the label
Estimated serum-level curves from published half-lives. Understand trough and peak, why twice-daily beats once, and when a compound has actually cleared.
Correlate against WHOOP
Pull recovery, sleep, and HRV and line it up against what you changed. Stop relying on vibes — watch the data move when the stack moves.
Substance research database
Mechanisms, receptor targets, and primary references for every compound — wired into your log so context is one tap away.
Who it's for
If you run a multi-compound protocol and your tracking system is still a tab in Google Sheets, you've outgrown it.
StackLog was built for nootropics, peptide, and HRT users who treat their own physiology like an experiment — and want their tooling to keep up.
- Track supplements, nootropics, peptides, and HRT in one log
- Catch interactions and redundancies before they cost you
- Reason about timing with real half-life math
- Tie protocol changes to recovery and sleep data
