Today's log
Who it's for
Track stacks, dose schedules, shelf life, and effects across multiple compounds simultaneously
Log compounds, monitor bloodwork trends, and track how your protocol affects training and recovery
Strength tracking, nutrition precision, body composition, and recovery monitoring in one place
Features
Most fitness apps weren't built for people running serious protocols. This one was.
Log doses, shelf life, and frequency for every peptide and compound in your protocol. See your full history and adherence at a glance.
Paste or photograph your lab results. AI parses the values, flags out-of-range markers, and tracks trends across panels over time.
Ask anything about your progress. The AI coach references your actual logs — weight, nutrition, bloodwork, recovery — not generic advice.
Log lifts with sets and reps, track meals and macros, and build daily habits for sleep and recovery — all on the same timeline as your protocol.
AI coach example
Pharmacology-specific answers — trough timing, ester half-life, and your pin schedule — not generic wellness fluff.
AI Coach
Protocol · Trough timing × enanthate PK
You
I'm on Test E 250 mg twice weekly (Mon/Thu). When should I draw blood to see trough Total T?
AI Coach
Based on your logged protocol and enanthate's ~4.5-day elimination half-life: **Steady state:** Allow ~4–5 half-lives (~18–23 days) from your first pin before interpreting trough levels. **Trough draw timing:** Draw **24 hours before your next scheduled pin** — for your Mon/Thu schedule, that's **Sunday morning** or **Wednesday morning** depending which trough you want. **Your last logged pins:** Mon 07:30 · Thu 07:45 (both 1.0 mL @ 250 mg/mL = 250 mg). **Why this matters:** Mid-cycle draws on long esters often over-read vs true trough; pre-pin draws align better with TRT monitoring conventions. Discuss target ranges with your clinician — this is scheduling guidance from your log data, not dosing advice.

Cross-metric · Ferritin × protocol timeline
Your ferritin dropped 40% in the 6 weeks following your last cycle. Consider iron supplementation before your next panel.

Roadmap
Pharmacokinetics, ester-aware logging, PCT, stack planning, and injection rotation — now available in Cyclodex.
Input compound, ester, dose, and injection frequency. Cyclodex renders a projected blood level curve using standard half-life calculations, with actual bloodwork values overlaid when available.
AvailableEvery compound entry captures name, ester type, concentration (mg/mL), injection volume, and vial tracking — so your log reflects what you actually pin.
AvailableSERM log with dose and duration, a dedicated recovery bloodwork view tracking LH/FSH/Total T post-cycle, and a clearance calculator from last pin date and ester half-life.
AvailableGantt-style timeline showing all active compounds with start/end dates, half-life tails, and your PCT window.
AvailableBody diagram and rotation log for site management, with next-site suggestions based on your injection history.

Why Cyclodex
Calorie counters and gym trackers stop where serious protocols begin. Cyclodex picks up there.
Comparison describes common product categories — not a specific competitor. Features vary by plan.
From the community
Trusted by serious protocol users across 40+ countries
“Finally a tracker that doesn't treat peptides as an afterthought. I can see my whole stack, bloodwork trends, and training in one place.”
“The AI coach actually references my logs. When I ask about recovery it cites my sleep and wellness data — not generic bro-science.”
“The PK overlay against my actual Total T panels finally made trough timing click. Ester-aware logging and the clearance calculator stopped me drawing blood way too early post-cycle.”
