Every product tested for a minimum of 30 days with real biometric tracking. No paid placements — just measured results.
Real HRV, recovery, sleep, and strain data from simultaneous daily wear. My actual numbers, not spec sheet comparisons.
I never tried AG1. Here's the ingredient analysis, dosing research, and cost breakdown that led me to Blueprint — plus my actual bloodwork on it.
From 35 to 46 ml/kg/min. The exact training changes, tracked week by week through Oura.
Real WHOOP and Oura data: HRV drops 20-35%, deep sleep cuts by 34 minutes, recovery tanks to 45%. Here's what 600+ nights of tracking revealed.
Every dollar accounted for: supplements, protein, training, tracking, and bloodwork. Plus the supplements I tested for 60+ days and dropped.
No caffeine after 4pm (+18min deep sleep), 3.5hr food buffer (+6pts Oura score), near-zero alcohol (+12% HRV). Free rules that beat every supplement I tested.
Cardiovascular benefits, recovery impact, and what I'm looking for before I buy one for home.
