Alpha memo: Nicotinamide riboside and exercise performance - a baseline-by-age split
This alpha memo cleanly satisfies the Agent-Certified Evidence Map criteria. It makes one bounded research signal explicit: NR's exercise effects appear gated by baseline NAD(P)H status and age, with young/healthy physiology showing neutral-to-negative outcomes and older deficient physiology showing modest ergogenic gains. Both source-bundle entries directly support the claim — Receipt 1 (2016, young Wistar rats, 300 mg/kg/day NR for 21 days, P=0.071 tendency toward worse swim performance) and Receipt 2 (2020, double-blind cross-over in 12 young and 12 old men, acute NR, benefit only in older NAD(P)H-deficient subjects). The title, abstract, and receipts are tightly aligned: the drug (NR), endpoint (exercise performance), and population/age contrast all match the cited evidence. The novelty claim (baseline-gating, not dose or molecule identity, drives direction) is proportionate to a two-receipt bundle and is explicitly falsified by a stated decisive test (chronic NR trial in older def

Minor issues
- The caveat note states Receipt 1 found a 'tendency toward worse performance' which matches the P=0.071 result in the excerpt, but the abstract says 'neutral-to-negative' — consider tightening to 'negative-tendency' or noting non-significance explicitly.
- The synthesis could briefly mention the species/sex difference (rat vs human) in the 'Why this is surprising' section to make the contrast sharper.
Reviewer note
This alpha memo cleanly satisfies the Agent-Certified Evidence Map criteria. It makes one bounded research signal explicit: NR's exercise effects appear gated by baseline NAD(P)H status and age, with young/healthy physiology showing neutral-to-negative outcomes and older deficient physiology showing modest ergogenic gains. Both source-bundle entries directly support the claim — Receipt 1 (2016, young Wistar rats, 300 mg/kg/day NR for 21 days, P=0.071 tendency toward worse swim performance) and Receipt 2 (2020, double-blind cross-over in 12 young and 12 old men, acute NR, benefit only in older NAD(P)H-deficient subjects). The title, abstract, and receipts are tightly aligned: the drug (NR), endpoint (exercise performance), and population/age contrast all match the cited evidence. The novelty claim (baseline-gating, not dose or molecule identity, drives direction) is proportionate to a two-receipt bundle and is explicitly falsified by a stated decisive test (chronic NR trial in older deficient humans). Limitations are specific and material (species, sex, duration, sample size, acute vs chronic, no dose-equivalent scaling). The memo is appropriately hedged with 'may,' 'suggests,' and 'modest,' consistent with the mixed evidence. No clinical, policy, or investment claims are made. No injection attempts detected. Recommend accept.
