Stop guessing if your stack is working. LynkDose is the peptide tracker built for serious biohackers — linking every dose to your biometrics so you can see how each compound lines up with your health data. Whether you need a peptide tracker, compound tracker, or dose log for BPC-157, Ipamorelin, or a complex multi-compound health protocol — LynkDose keeps every dose logged, every vial tracked, and every result connected to your health data. LOG EVERY DOSE Your personal peptide log in seconds. Log any compound with the dose you took, date and time, injection site, weight, notes, and photos. Quick Log mode pre-fills your last-used amounts so repeat logging takes two taps. Supports dozens of pre-loaded compounds — BPC-157, TB-500, Ipamorelin, CJC-1295, GHK-Cu, PT-141, Epitalon, Selank, Semax, and more — plus unlimited custom compounds and single-vial blends. PEPTIDE INVENTORY Track your vials — unmixed, mixed, and pre-mixed. Record vial size, remaining amount, expiration dates, and photos. Stock updates automatically as you log, and low-stock and expiration alerts keep you ahead of your supply. COMPLIANCE & REMINDERS Set per-compound reminders at any frequency — daily, every other day, twice weekly, weekly, or custom days. See your compliance score for each compound as a percentage of scheduled vs completed doses. INJECTION SITE MAPPING A full-body heatmap tracks every injection site across abdomen, thighs, arms, shoulders, glutes, and delts. Avoid overuse and manage rotation across your entire peptide protocol. BODY METRICS & PROGRESS TRACKING Track key metrics over time with trend charts synced from Apple Health. Log progress photos alongside your dose logs to see how your peptide protocol is working over time. BIOMETRIC CORRELATION Reads sleep, resting heart rate, HRV, blood glucose, steps, active energy, body fat, and VO2 Max from Apple Health. See how each compound in your stack lines up with your health metrics over time. LAB RESULTS & BLOODWORK Upload bloodwork and lab results directly into LynkDose. Line up biomarkers with your dose logs from the same time frame and see how your bloodwork changes over time. WEEKLY RECAP Every Sunday, LynkDose summarizes your week: adherence, biometric trends, and what changed. SIDE EFFECTS & PEPTIDE DIARY Track side effects and log daily mood with sub-metrics for energy, focus, pain, libido, and anxiety. Use LynkDose as your peptide diary and supplement log. Journal entries auto-correlate with same-day dose logs. SHARE YOUR PEPTIDE STACK Share your full peptide stack with others — compounds, compliance, progress, and results in one shareable card. Export progress photos from your peptide protocol to show how your stack is performing over time. COMPOUND LIBRARY An educational reference for dozens of compounds: what each one is, how much research exists, known considerations, and links to published studies. Not medical advice. AI PROTOCOL ASSISTANT Our AI has full context of your logs, inventory, reminders, and biometrics. Ask it to analyze your history, surface patterns, or log a dose. It describes what your data shows; it doesn't give medical advice or dosing recommendations. LynkDose is the peptide tracker built for biohackers managing 2–10+ compounds simultaneously. Not a general medication tracker — a precision tool for serious protocol tracking. LynkDose is a logging and tracking tool: it does not provide medical advice, diagnose, or recommend doses.
