Stop guessing if your stack is working. LynkDose is the peptide tracker built for serious biohackers — linking every dose to your biometrics so you know exactly what each compound is doing to your body. Whether you need a peptide tracker, compound tracker, or dose tracker 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 and dose tracker in seconds. Log any compound with dose amount, 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 34 pre-loaded compounds — BPC-157, TB-500, Ipamorelin, CJC-1295, GHK-Cu, PT-141, Epitalon, Selank, Semax, and more — plus unlimited custom compounds. PEPTIDE CALCULATOR & RECONSTITUTION Built-in peptide calculator for reconstitution math. Enter your vial amount, BAC water volume, and target dose to get exact draw volumes in ml and syringe units instantly. No math, no guesswork. PEPTIDE INVENTORY & DOSE MANAGER Track your peptide inventory across three states: unreconstituted, reconstituted, and pre-mixed. Log concentration, remaining volume, expiration dates, and photos. Low stock and expiration alerts keep your peptide tracker 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 exactly how each compound in your peptide tracker connects to your health metrics over time. LAB RESULTS & BLOODWORK Upload bloodwork and lab results directly into LynkDose. Correlate biomarkers with your dose logs during the same time frame — see exactly how your peptide protocol is affecting your bloodwork panel over time. WEEKLY RECAP Managing a full peptide stack — every Sunday LynkDose synthesizes your week as a peptide tracker, adherence rates, 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. AI PROTOCOL ASSISTANT Our AI will have full context of your peptide logs, inventory, reminders, and biometrics. Ask it to analyze your protocol, surface patterns, or log a dose. Your personal biohacking coach that actually knows your data. 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.
