Interactive Longevity Stack & Conflict Auditor
Stacking longevity interventions without pharmacokinetic chrono-spacing causes molecular antagonisms (e.g. cold immersion blunting muscle hypertrophy; metformin blunting Zone 2 mitochondrial adaptations). Audit your daily routine in real-time.

Biochemical & Timing Antagonisms (10 LEVL Rules)
Cold Immersion Blunts Post-Lift Hypertrophy Signaling: Cold water immersion (<55°F) within 4 hours post-lifting acutely constricts vascular beds, blunts localized COX-2 inflammatory signaling, and suppresses p70S6K and satellite cell activation, reducing muscle hypertrophy adaptations by up to 50% (Roberts et al., 2015).
Separate cold water immersion by at least 4 hours after resistance training, or perform cold plunges upon waking before training. [CHRONO CLASH: Scheduled ~0.0h apart; requires ≥4h separation]
Metformin Blunts Mitochondrial Complex I Exercise Adaptations: Metformin reversibly inhibits mitochondrial Complex I in skeletal muscle. Co-administering Metformin immediately around aerobic exercise blunts the training-induced increase in whole-body VO2 max and whole-muscle mitochondrial respiration by approximately 50% in healthy individuals (MAST Study, Braun et al., 2019).
In non-diabetic longevity protocols, dose Metformin in the evening, separated by at least 4 hours from cardiovascular training sessions. [CHRONO CLASH: Scheduled ~0.0h apart; requires ≥4h separation]
