Pharmacokinetic blood level simulator
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.
Your cycle. Your data. Your edge. Everything your protocol needs — from daily logging to pharmacokinetic planning.
Log doses, shelf life, and frequency for every peptide and compound in your protocol.
Paste or photograph lab results. AI parses values, flags out-of-range markers, and tracks trends.
Ask about your progress — the coach references your actual logs, not generic advice.
Log lifts, track meals and macros, and build daily habits for sleep and recovery — all on one timeline.
Concrete signals tied to your protocol timeline, bloodwork panels, and recovery data.
Not generic wellness tips — answers grounded in ester half-life, pin schedule, and your logged data.

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.

Built for users running structured compound protocols — logging, simulation, and recovery tracking in one place.
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.
Every compound entry captures name, ester type, concentration (mg/mL), injection volume, and vial tracking — so your log reflects what you actually pin.
SERM 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.
Gantt-style timeline showing all active compounds with start/end dates, half-life tails, and your PCT window.
Body diagram and rotation log for site management, with next-site suggestions based on your injection history.
