Protocol Tracker logs your peptides, TRT, and compound cycles, then models real blood-level curves with a validated two-compartment pharmacokinetic engine — so you can see what's actually happening between doses, not just when you last logged one.
Built for people who want to actually understand their protocol, not just check boxes.
One view of everything active — doses due, recent logs, and current projected levels.
A structured compound library with half-lives and dosing data behind every entry.
Plan a full cycle in advance and see it laid out on a real schedule, not a spreadsheet.
Log actual doses with a time picker, and keep a real history of what happened vs. what was planned.
Track lab results over time and compare them against your modeled projections.
Rotate sites with a visual map so you're not guessing where you last injected.
Keep context — how you're feeling, side effects, anything worth remembering — next to the data.
Pull your full history out whenever you want it. Your data, not locked in.
Most trackers just log a dose and move on. Protocol Tracker models absorption and elimination with a two-compartment pharmacokinetic curve, checked against primary literature rather than guesswork — so the projected levels you see are grounded in the same math used in actual pharmacokinetic research.
That means you can see estimated blood levels between doses, not just the moment you logged one.
We're building a family of fitness apps that talk to each other — starting here, with more on the way. Get early access and a launch discount when the bundle goes live.
One plan, everything included, while we're in early access.
Most trackers just record that you took a dose. Protocol Tracker models the actual pharmacokinetics — a two-compartment absorption/elimination curve — so you can see estimated blood levels at any point in your cycle, not just log entries.
