(1) No AAS shall be permitted to test samples collected from racing horses except for endogenous concentrations of the naturally occurring substances Boldenone, Nandrolene, and Testosterone at concentrations less than the indicated thresholds.(2) Concentrations of these AAS shall not exceed the following free (i.e., not conjugated) steroid concentrations in plasma or serum:(a) Boldenone - A confirmatory threshold not greater than 25 picograms/milliliter for all horses, regardless of sex;(b) Nandrolone - A confirmatory threshold not greater than 25 picograms/milliliter for fillies, mares, and geldings; males horses other than geldings shall be tested for nandrolone in urine(c) Testosterone - A confirmatory threshold not greater than 100 picograms/milliliter for fillies, mares, and gelding.(3) Total concentrations of these AAS shall not exceed the following total concentrations in urine after hydrolysis of conjugates:(a) Boldenone - A confirmatory threshold not greater than 1 nanogram/milliliter for fillies, mares, and geldings; a confirmatory threshold not greater than 15 nanograms/milliliter in male horses other than geldings;(b) Nandrolone - A confirmatory threshold not greater than 1 nanogram/milliliter for fillies, mares, and geldings; a confirmatory threshold not greater than 45 nanograms/milliliter (as 5a-estrane-3p,17a-diol) of urine in male horses other than geldings;(c) Testosterone - A confirmatory threshold of not greater than 55 nanograms/milliliter of urine in fillies and mares (unless in foal); a confirmatory threshold of not greater than 20 nanograms/milliliter in geldings(4) Any other AAS are prohibited in racing horses.(5) The sex of the horse must be identified to the laboratory on all pre-race and postrace samples designated for AAS testing.(6) If an anabolic steroid has been administered to a horse in order to assist in its recovery from illness or injury, that horse may be placed on the Veterinarian's List in order to monitor the concentration of the drug or metabolite in urine or blood. After the concentration has fallen below the designated threshold for the administrated AAS, the horse is eligible to be removed from the list.006.06.21 Ark. Code R. 002
