Abstract
Young (2-4 months) and aged (14-16 months) male Swiss-Webster albino mice (n = 7 per group) were subcutaneously injected with 20 mg/kg/day dehydroepiandrosterone sulfate (DHEAS), progesterone (P), DHEAS + P, or vehicle control and trained over a 5-day period in a Morris water maze. The subjects were tested 48 hr after training for memory recall as measured by latencies to locate the hidden platform, and trunk blood was collected immediately thereafter. As expected, latency to platform decreased for all groups over the 6 testing days, with aged mice taking longer to reach platform than did young mice. However, results did not support the hypotheses that DHEAS-treated mice would exhibit shorter latencies and that P-treated mice would show longer latencies to platform in comparison with age-matched controls. These results raise doubts about the effectiveness of commercially available supplements claiming to promote enhanced memory in humans.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
