Compound & protocol management
Plan, log, and adjust TRT, GLP-1, peptide, SARM, and ancillary protocols. Esters, half-lives, cycle phases, blood-test timing, and PK simulation built in. The most accurate compound database we've seen anywhere.
Train safe.
Track smart.
The only health-tracking app that connects every signal you log: bloodwork, workouts, compound protocols, nutrition, sleep, journal. You finally see what actually moves your numbers.
- 330 compounds tracked
- 30+ bloodwork markers
- 3 built-in calculators
- 100% free, forever
Illustrative example: a 12-week protocol on Test E plus BPC-157. Total testosterone rose from 412 to 893 ng/dL. Bench 1RM rose from 245 to 295 lb (a 20% increase). Joint-pain score dropped from 6.2 to 2.1 out of 10 after BPC-157 was introduced. Subjective energy rose from 5.4 to 8.2 out of 10. Auto-insight: Test E correlates 0.84 with bench progression; BPC-157 correlates negative 0.71 with joint pain; sleep onset improved 31 minutes. Numbers are illustrative; your VitaLog view uses your own data.
Every signal you log talks to every other.
Most apps silo your data: workouts here, food there, bloodwork in a PDF you forget about. VitaLog puts everything on one timeline and surfaces the connections between what you put into your body, what you ask of it, and what your numbers say back.
01
Compound × bloodwork
Layer your TRT, GLP-1, peptide, and ancillary protocols against your labs over time. See how E2, hematocrit, lipids, prolactin, and SHBG actually respond to your dosing, not someone else's anecdote.
02
Training × recovery
Workout volume, intensity, and progression overlay against sleep, RHR, mood, soreness, and journal entries. The correlation engine flags when training load is outpacing recovery, before it shows up in your labs.
03
Nutrition × performance
Macros, micros, water, supplements, cross-correlated with strength PRs, body composition, and energy markers. See whether your protein target is actually moving the needle, or if it's something else entirely.
04
Journal × everything
Mood, libido, sleep quality, side effects, life events. Every journal entry is queryable against every other data stream so a "bad week" stops being a vibe and starts being a data point.
What people use VitaLog for first.
Pick the pillar that matches you, or use all three from day one. The correlation engine works the same regardless of where you start.
Workout tracking
Sets, reps, RIR, supersets, body-map heat, mobility log, rest-timer, PR detection. Tracks volume by muscle group across sessions and surfaces it against your sleep and recovery markers.
Bloodwork & biomarkers
Upload PDF lab reports or enter values manually. Reference ranges, draw-timing guidance, trend lines, glossary explainers. See E2, hematocrit, lipids, free-T, SHBG and 30+ markers in context with everything else you log.
Plus: nutrition (USDA + OpenFoodFacts), journal & goals, hormonal cycle tracking, photo-encrypted progress, clubs, and more.
Whatever you came here for, start here.
VitaLog works for general fitness, weight loss, and longevity tracking. It also works for serious protocol management. We don't pretend those audiences are the same. Pick the path that fits.
For everyday tracking
Workouts, nutrition, journal, sleep, weight, and bloodwork all in one place, without the spreadsheet sprawl. No compound or protocol features unless you ask for them.
- Every workout split, calculator, and food database you'd expect
- Bloodwork upload, trend lines, glossary & reference ranges
- Goals, streaks, journal, photo progress (encrypted)
- Auto-correlations across everything you track
For protocol & bio-research
Built for serious users running TRT, GLP-1s, peptides, hormonal cycles, or PED protocols. Harm-reduction first, evidence-driven, and the only app that ties dosing to your actual labs and training response.
- Full compound database with esters, kinetics, interactions
- PK / serum simulation across compound stacks
- Bloodwork-aware protocol planning & adjustments
- Optional Research Program, anonymized data for science
What other apps don't do.
Everyone tracks something. VitaLog is the only one that ties every signal to every other, so a "did this protocol help me?" question has a real answer, not a vibe.

People like you, using it for…
TRT optimization
Dial dose, ester, frequency, and ancillaries against your actual E2, hematocrit, lipids, and free-T trajectory.
GLP-1 weight loss
Semaglutide / tirzepatide titration with side-effect tracking, dose calculator, and body-composition correlation.
Peptide protocols
BPC-157, TB-500, sermorelin, ipamorelin and others, with reconstitution math, dosing schedules, and stack simulation.
Athletic performance
Volume periodization, recovery-aware programming, PR detection, and the food / supplement variables that actually matter.
Hormonal cycle sync
Cycle-aware training, nutrition, and mood tracking, built for women who train hard and want to plan around biology.
Longevity & biomarkers
Quarterly lab panels, supplement protocols, sleep / RHR / HRV trends, correlated against the things you actually do.
Health data should belong to the person who lived it.
VitaLog was built because no existing app could honestly answer "did this protocol actually help me?", and because every app that came close was either packed with ads or refusing to track the things you actually wanted to track.
We're solo-founded, EU-hosted, and funded by donations and an opt-in research program. No ads. No third-party trackers. Transparent about every sub-processor we use. And we built the entire app so you can export, port, or delete everything in a single tap. Read the full mission →
Trust isn't a marketing line. It's the architecture.
