- Garmin Forerunner 965
- Optical HR sensor (wrist); nightly HRV-status algorithm
- Accelerometer + HR; ~85% agreement with polysomnography for sleep stages
- Yes. Integrates HRV, stress, activity
- .FIT file export via Garmin Connect; compatible with third-party analysis tools
- Best for researchers needing granular data exports and multi-day trend analysis. Premium tier without unnecessary features
- Garmin Fenix 7 Pro
- Optical HR + optional chest strap; continuous HRV logging option
- Accelerometer + Pulse Ox; validated for REM/deep sleep detection
- Yes. Includes Training Readiness score
- .FIT file export; API access for custom integration
- Ideal for multi-modal research (cycling, swimming, resistance training) where contextual load tracking matters alongside peptide effects
- Garmin Venu 3
- Optical HR sensor; nightly HRV-status only (no intraday logging)
- Advanced sleep tracking with nap detection; ~80% stage accuracy
- Yes. Simplified recovery insights
- Limited export; primarily app-based review
- Sufficient for basic BPC-157 outcome tracking but lacks granular intraday data needed for half-life correlation studies
- Whoop 4.0 (comparison)
- Photoplethysmography (PPG); continuous HRV with raw RMSSD output
- Sleep coach algorithm; comparable accuracy to Garmin Fenix series
- Recovery score (similar concept to Body Battery)
- CSV export of raw HRV, HR, and sleep data
- Strong alternative for HRV-focused research; no GPS or activity tracking. Purely recovery-centric if that's the sole focus
