NAD+ vs SS-31

NAD+ wins for broad systemic effects, ease of sourcing legitimate material, and established human protocols for post-cycle, neuroprotective, and whole-body recovery. It's highly stacked, works for most users, and protocol design mostly comes down to tolerability (IV/SC rate, dose).

SS-31 wins for potency as a direct mitochondrial repair agent. Nothing else binds cardiolipin and restores oxidative phosphorylation this cleanly, especially for users with visible mitochondrial stress—think masters-age athletes, chronic fatigue, or serious on-cycle cardiac/oxidative stress. It acts fast, can be stacked with NAD+ precursors, but is expensive at effective doses and sourcing quality matters.

Pick NAD+ if:

• You want global improvements in energy, sleep, cognitive function, or post-cycle hepatic recovery
• You're building a longevity stack alongside NR/NMN, rapa, GH, and want systemic support
• You're post-AAS/oral and targeting quick mitochondrial/organ reset
• You need something with wide human data and community reference protocols
• You want an option with fewer sourcing pitfalls and easy fit into most regimens

Pick SS-31 if:

• You need targeted mitochondrial rescue for aged muscle, cardiac stress, or post-viral/overtraining fatigue
• You have ME/CFS, chronic overreaching, or visible "crash" symptoms NAD+ didn't touch
• You're running heavy cycles and want direct cardiac oxidative stress insurance
• You're stacking with MOTS-c or urolithin A and want synergy in mitochondrial-specific repair
• You're okay paying for pharma-grade peptide and can source it reliably
