NAD+ vs Epitalon

NAD+ wins for mitochondrial/metabolic rejuvenation, post-cycle liver support, and fast-acting improvements in energy and cognitive clarity. It's also widely studied, easy to stack, and fits naturally with almost any other protocol. Most evidence supports performance, recovery, and general anti-aging effects. The protocol is stricter (IV/SC only; oral is useless) but well-mapped.

Epitalon wins for direct telomere maintenance, sleep/circadian support, and longer-term cellular 'youth' via telomerase upregulation. It's cleaner in terms of side effect profile, has an easier SubQ administration (short course once/year, or nightly microdose), and has no known short-term downsides aside from the generic peptide sourcing sketchiness. Its telomerase/epigenetic-age story is unique, though not as broadly validated.

Pick NAD+ if:

• You want rapid post-cycle recovery (especially after orals or harsh cycles)
• You're after immediate mitochondrial/energy/cognitive benefits
• You want metabolic support, improved endurance, or cardiovascular benefits
• Stacking for overall longevity or as part of a broad anti-aging protocol
• Tolerate IV or SubQ protocols; okay with logistics and discomfort risk

Pick Epitalon if:

• Your primary goal is slowing biological aging (telomere length, epigenetic markers)
• You want to pulse yearly for long-term benefits, not ongoing admin
• You're focused on improving sleep quality/circadian rhythm (especially at night)
• You want minimal side effects and simple SubQ self-admin
• Prefer a less "stimulating" effect (Epitalon is gentler day-to-day)
