Systemic energy & cell repair
Step-up loading phase then steady maintenance, diluted to reduce injection sting.
6 weeks, 3 shots a week in maintenance
Upper end of the guide's maintenance range (2-3 times per week).
6 weeks, 2 shots a week in maintenancerecommended

Why:
What sources report this compound changes, or say to check. A record of the evidence, not targets or advice.
With oral nicotinamide riboside (a precursor, not injected NAD+) whole-blood NAD+ rose 22%, 51% and 142% at 100, 300 and 1000 mg within 2 weeks, with no significant difference in adverse events vs placebo. No source found for injected NAD+.
