Minor issues

• One-sentence alpha could explicitly note the small-sample tendency (not statistical significance) in Receipt 1 to keep the contrast proportionate.
• VO-based performance abbreviation 'VO' in Receipt 2 description could be expanded to VO2max for reader clarity, though the source uses similar shorthand.

Reviewer note

This alpha memo delivers one bounded, source-grounded research signal: nicotinamide riboside's exercise-performance effect appears context-dependent, trending negative in a young-animal chronic model and positive in older humans with lower baseline NAD(P)H. The two receipts are tightly aligned with the title's anchor (NR + exercise performance), species/age context is explicitly contrasted, and the memo's own caveats (n=18 small sample, tendency not significance, species/dose/route/duration differences, acute vs chronic) honestly bound the claim. The falsifier clause is specific and falsifiable. Source grounding is strong: both DOIs and excerpts match the cited findings — Receipt 1 (n=18 Wistar rats, 300 mg/kg/day, 21 days, tendency toward worse swimming) and Receipt 2 (12 young + 12 old men, acute crossover, NAD(P)H increase in old, improved performance). The Receipt 2 excerpt explicitly references the prior young-rat impairment finding, reinforcing the cross-context contrast the memo foregrounds. Limitations are material and specific (small n, tendency vs significance, species/dose/duration confounders), and the gaps section names a decisive future trial design. No clinical, policy, or investment claims are made. Recommend accept.
