038-8 Wyo. Code R. § 8-2
(a) No horse participating in a race shall carry in its body any foreign substance except as provided in these Rules.
(b) A finding by the chemist that a foreign substance is present in the test sample shall be prima facie evidence that such foreign substance was administered and carried in the body of the horse while participating in a race. Such a finding shall also be taken as prima facie evidence that the trainer and his agents responsible for the care or custody of the horse have been negligent in the handling or care of the horse. The presumption of negligence may be rebutted by competent evidence, otherwise the absolute insurer rule for trainers will be deemed to have been violated.
(c) No Androgenic-Anabolic Steroid shall be permitted in a test sample collected from racing horses except for residues of the major metabolite of stanozol, nandrolone, and the naturally occurring substances boldenone and testosterone at concentrations less than the indicated thresholds.
(d) Concentrations of these Androgenic-Anabolic Steroids shall not exceed the following urine threshold concentrations for total (i.e., free drug or metabolite and drug or metabolite liberated from its conjugates):
(e) Any other Androgenic-Anabolic Steroid are prohibited in racing horses.
(f) Post-race urine or blood samples collected from intact males must be identified to the laboratory.
(g) Any horse to which an anabolic steroid has been administrated in order to assist in the recovery from illness or injury may be placed on veterinarian's list in order to monitor the concentration of drug or metabolite in urine. After the concentration has fallen below the designated threshold for administrated Androgenic-Anabolic Steroids, the horse is eligible to be removed from the list.
(h) A foreign substance of accepted therapeutic value may be administered as prescribed by a veterinarian when test levels and guidelines for its use have been established by the Veterinary-Chemist Advisory Committee of the Association of Racing Commissioners International and approved by the Commission.
(i) No substance shall be administered to a horse entered to race within twenty-four hours prior to post time of the race in which the horse is entered except that furosemide ("Lasix") may be administered under the supervision of the Official Veterinarian as prescribed in these Rules.
(j) When a foreign substance of accepted therapeutic value is administered or prescribed by a veterinarian for a horse that is entered to race, the veterinarian must make a report of that substance and submit the report to the Commission Veterinarian by 9:00 a.m. of the race day and must report immediately following administration of Lasix.
(k) The administration of 250 milligrams of furosemide ("Lasix") shall be permitted four or more hours prior to post time for the prophylactic treatment of a known bleeder. Stabling until race reporting time in a holding facility approved by the Commission Veterinarian is required.
(l) Bute is the only approved non-steroidal anti-inflammatory drug (NSAID) that may be present in a horse's body while it is participating in a race. The presence of more than one NSAID at any test level is forbidden. A horse running on an approved NSAID will be required to run on an approved NSAID in all subsequent races at the meet, unless special permission for the horse to be removed from the "bute" list is granted by the Commission Veterinarian and the Stewards.
(m) The test level of phenylbutazone and its metabolites under this rule shall not be in excess of five (5) micrograms per milliliter (MCG/ML) in the blood.
(n) Each and every horse entered to race may be subjected to a veterinary examination for racing soundness and health on race day, not later than two hours prior to official post time for the first race.
(o) Every horse that suffers a breakdown on the race track, in training or in competition, and is destroyed, and every other horse which expires while stabled on the race track shall undergo a post-mortem examination at a time and place acceptable to the Commission Veterinarian to determine the injury or sickness which resulted in euthanasia or natural death.
(p) The Commission may direct the official laboratory to retain samples for future analysis.
(q) The fact that purse money had been distributed prior to the issuance of a laboratory report shall not be deemed a finding that no chemical substance has been administered in violation of these Rules to the horse earning the purse money. No portion of any purse shall be redistributed as a result of a positive finding for a preserved sample after the 16th day following the race in question.
(r) Disciplinary action for a positive finding of a preserved sample shall be taken at the discretion of the Commission.
