Abstract
Abstract Cobaltous ions (Co 2+ ) stabilize HIFα, increase endogenous erythropoietin (EPO) production, and may, therefore, be used as a performance‐enhancing substance. To date, the dosage necessary to stimulate erythropoiesis is unknown. The aim of this study was, therefore, to determine the minimum dosage necessary to increase erythropoietic processes. In a first double‐blind placebo‐controlled study ( n = 5), single oral Co 2+ dosages of 5 mg ( n = 6) and 10 mg ( n = 7) were administered to healthy young men. Cubital venous blood and urine samples were collected before and up to 24 hours after Co 2+ administration. In a second study, the same daily Co 2+ dosages were administered for five days (placebo: n = 5, 5 mg: n = 9, 10 mg: n = 7). Blood and urine samples were taken the day before administration and at day 3 and day 5. Plasma [EPO] was elevated by 20.5 ± 16.9% at 5 hours after the single 5‐mg administration ( p < 0.05) and by 52.8 ± 23.5% up to 7 hours following the 10‐mg Co 2+ administration ( p < 0.001). Urine [Co 2+ ] transiently increased, with maximum values 3–5 hours after Co 2+ ingestion (5 mg: from 0.8 ± 1.1 to 153.6 ± 109.4 ng/mL, 10 mg: from 1.3 ± 1.7 to 338.0 ± 231,5 ng/mL). During the five days of Co 2+ application, 5 mg showed a strong tendency to increase [EPO], while the 10‐mg application significantly increased [EPO] at day 5 by 27.2 ± 26.4% ( p < 0.05) and the immature reticulocyte fraction by 49.9 ± 21.7% ( p < 0.01). [Ferritin] was decreased by 12.4 ± 10.4 ng/mL ( p < 0.05). An oral Co 2+ dosage of 10 mg/day exerts clear erythropoietic effects, and 5 mg/day tended to increase plasma EPO concentration.

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
