To resubmit, address

1. Remove the saffron/Alzheimer's rat receipt (10.71878/jpah.2025.1197082) entirely; it is off-topic for a beta-alanine memo. If kept, it must be reclassified as a cross-compound contrast and the title must be reframed to reflect that.
2. Remove the HMB protocol receipt (10.1136/bmjopen-2018-025723) entirely, or replace it with a receipt that actually tests beta-alanine in older adults undergoing resistance training.
3. Rewrite the central claim to reflect the only directly relevant receipt (2018 beta-alanine RCT): beta-alanine did not augment the effects of endurance-based resistance training on most strength/power/ADL outcomes in older adults, with the caveat that the trial was small (n=27) and used a specific 3.2 g/day dose and endurance-style protocol.

Major issues

• The third receipt (10.71878/jpah.2025.1197082) is about saffron supplementation and resistance training in a rat Alzheimer's model - it does not study beta-alanine at all. This is a misaligned receipt that confounds the central claim about beta-alanine, violating title/source alignment rules. The memo acknowledges this receipt is only indirect (animal, amyloid beta not beta-alanine), yet still includes it in the evidence ledger as supporting the thesis.
• The second receipt (10.1136/bmjopen-2018-025723) is a protocol paper about HMB (beta-hydroxy-beta-methylbutyrate) supplementation with resistance training, not beta-alanine. Labeling it as a 'beta alanine resistance training older adults trial' with a 'negative' beta-alanine direction is a misattribution. The excerpt confirms it is a HMB trial protocol (UMIN000028560).
• The first receipt is the only one that directly addresses beta-alanine + resistance training in older adults, and it reports a null effect on most measures (not a negative effect for the older adults). The remaining 1RM leg press finding was driven by resistance training, not by beta-alanine. The memo's claim of a 'null and negative signal' overstates this evidence.

Minor issues

• The memo's abstract is circular, repeating the title verbatim as the core finding without adding analytic content.
• The 'Signal score: 100 (novelty 58, evidence 100)' is presented without methodological basis and reads as a fabricated metric.
• The source query 'beta alanine blunts resistance training' is a leading/negative question and appears nowhere in the actual literature; the retrieval is not transparently derived from this framing.

Reviewer note

The memo is anchored on a clear, bounded null finding (beta-alanine does not enhance endurance-based resistance training in older adults) and that single anchor is well-supported by receipt 10.1080/19390211.2017.1406422. However, the remaining two receipts do not support the stated thesis: the HMB protocol paper has no beta-alanine arm, and the saffron/Alzheimer's rat paper is a different compound and different population. Including both as 'counter' or 'replication' receipts in the evidence ledger while framing the memo around beta-alanine is a material title/source misalignment. The prose acknowledges heterogeneity and 'not clinical advice,' but the claim ledger and abstract nevertheless present the bundle as a coherent negative/ null signal for beta-alanine, which overstates what the single on-topic receipt supports. Because the central claim rests on a misaligned evidence bundle rather than a scope mistake that bounded edits can fix, reject is the correct call; the manuscript needs a source-bundle reset, not just a rewrite.
