The following substances and related compounds are banned by the DFAC and their use constitutes grounds for dismissal from DFAC competitions and suspension from membership in the organization.

ANABOLIC STEROIDS

TESTOSTERONE
(Testosterone/epitestosterone Ratio)

The T/E ratio is used to measure the presence of exogenous testosterone, or illicit elevation of testosterone levels. A T/E ratio in excess of 4/1 is ruled as positive, no matter what the cause.

GROWTH HORMONES
(pharmaceutical HGH, HCG and any other related compounds)

HORMONES AND PRECURSORS
The use of any hormone including T3 and T4 (injectable, oral, sublingual or otherwise) including insulin is strictly prohibited. All hormonal precursors ( androstenedione, 19 norandrostenedione, etc.) are banned.

PRESCRIPTION DURETICS
(Fen-Phen and all other prescription weight-loss substances used for bodybuilding purposes, even when physician-prescribed are banned by the DFAC)

PSYCHOMOTOR STIMULANTS

MUSCLE IMPLANTS OF ANY KIND

CHEMICALS/DRUGS USED TO DECEIVE OR PASS POLYGRAPH

CLENBUTEROL AND GHB
ANY ILLEGAL OR ILLICIT BODYBUILDING DRUG OR SUBSTANCE

ANY FDA-BANNED SUBSTANCE UNLESS INDICATED

ANY IOC-BANNED SUBSTANCE UNLESS INDICATED

Note: Should there be an elevated T/E ratio in excess of the 4/1 limit, the athlete will be ruled as positive (failure). Likewise the presence of any banned substance in the urine (i.e. nandrolone) no matter how it arrived there is ruled as positive (failure)
Products that contain ingredients that have chemical names similar to anything on the banned substance list could potentially cause a positive urine test result. Check with the DFAC drug testing officials if uncertain as to whether a particular product is disallowed or not.
Any use of a banned substance in the case of a medical circumstance, requires an application for exemption. This should be initiated by a letter from a doctor which should accompany this application. The DFAC will thereupon investigate the substance in question and its usage and make its own decision on whether you are eligible for DFAC Competitions.
