Key differences
Mechanism-level
What separates these at the receptor/pathway level? Be specific. One paragraph max.
Biometric-level
How do the wearable signals differ? HRV, RHR, sleep architecture, recovery. Be concrete with numbers where evidence allows.
Practical-level
Dosing logistics, detection window, confound profile, stack interaction weight.
Shared mechanisms
What do they have in common that matters for Vitals?
Vitals relevance
Explicitly: what does this mean for HRV interpretation, readiness scoring, coaching decisions, or stack logic?
Risks and uncertainty
Where is evidence thin? What remains contested? Be direct.
