Every tracking feature. No paywall.
Peptide protocol tracking
Log every dose, every day. Stack tracking for multi-peptide protocols. Reminders, cycle calendars, washout periods. Built around real protocols (BPC-157, GHK-Cu, CJC/Ipamorelin, GLP-1s, TB-500), not generic supplement reminders.
Hormone replacement tracking
TRT, BHRT, perimenopausal protocols. Injection schedule, lab review timing, dose changes, side effect notes. Ties symptom tracking (energy, libido, mood, sleep) to your dose changes so patterns surface.
Lab result upload + history
Upload prior bloodwork PDFs from Quest, LabCorp, or any lab. Auto-parsed into trend charts. See IGF-1, total/free testosterone, estradiol, ApoB, HbA1c, and 100+ markers over time. Free forever.
Daily metrics + journaling
Energy, sleep, mood, body composition, performance — all in one daily check-in. Apple Health and Garmin/Oura/Whoop integrations. Notes get tied to your protocol changes so you can see what worked.
Nutrition logging
Macro tracking with protocol-aware targets. If you're on a GH peptide that increases insulin resistance, the app surfaces guidance on carb timing. Not generic calorie counting.
Protocol education library
Hundreds of articles, videos, and short reads on peptides, hormones, longevity, and metabolic health. Written by KAYU's clinical team. Free.
Symptom + side effect log
Quick-add common side effects (water retention on GH peptides, hot flashes on AI'd protocols, injection site reactions). Every entry timestamped and exportable as a PDF for any provider.
Wearable integration
Apple Health, Garmin Connect, Oura, Whoop, Eight Sleep. Auto-sync HRV, sleep stages, resting heart rate, recovery score. Visualize against your protocol changes.
Where the line is.
Tracking, education, and lab visualization are free forever. Anything that involves a provider — consults, ordering, bloodwork, messaging — is part of the $49 consult or a membership.
